So boring I'm crying tears of joy
After a while using these IEMs, I have to say, they are truly god tier for the price they go for. I got these at a steep discount ($69, nice), but at anything under $100 (Which they're still about under as of me writing this), you will not get remotely close to something as uncolored and pure as this. Getting it out of the way, and the Ety diehards may not like this, I threw away the triple flanges, and also disliked the double flanges. I've had good experiences with those style tips on my other IEMs, but they are horribly painful here, and not as isolating as the tips I eventually settled on, the Shure Yellow Foam tips. Let's not beat around the bush, these things NEED to go deep, or else they'll sound kinda weird and quiet, which I figured out real fast as I went through many tips. While audiophiles say they're not the best option for sound quality, I feel that the two best tips for these are the official Etymotic foam tips (Beige), and the Shure Yellows. The beiges are long, and currently don't play nice with my ears, but the Shures cut off just enough length to allow the IEMs to go in all the way, and also stay comfortable for hours, without any readjustment needed. Both are borderline the same foam, just with different stems and adhesives (Shures are better here), so it's just down to length preference. There's a huge problem with the IEMs besides the aural violation pack-in tips, and that's the cable. "Cable down and deal with it" seems to be the the way they're meant to be used, but the microphonics are horrible when they're like that, to the point they'll drown out your own voice, and not just the ones in your head. People online say "Cable up and deal with the strange looks", and that helps, but then the issue is fitting the IEMs in when there's nothing for the cable elbow to rest against. I had a solution for this, "Cable down, UNDER, AND AROUND". Doing this (Also using the chin cinch) allows me to insert the IEMs as intended, and also kill the microphonics, as well as giving the IEMs more protection from tugging. You can even lay on your side with the IEMs like this, which you can't do cable up. With all the hat tricks out of the way, the sound. I love them. Neutral, no shrill highs, no obnoxious ear murdering bass boost, not tin-can quality, not muffled, just plain and simple clarity. The isolation, somehow, is better than any earplug I've ever used. Everything is just gone, it's almost scary, to the point where I now use an app on my phone to pass through mic audio so I'm not completely deaf when using these. It's freaky when I turn off the passthrough, and everything from people walking and talking, down to the person in front of me, just completely go away. The look... they're there, then you put them in, and then they're gone, like earplugs. I like the really understated appearance of them, nothing extravagant, not filled with weights to make it feel substantial, just two light tubes that produce sound, and vanish in your ears, leaving just thin cables going into your ears as the only hint that you're not listening to what's around you. I love these, I can wear them for the whole day, and feel like I'm in a world of my own. I've had the Ety experience, and I cannot go back. I'm no audiophile, but I feel like I've cheated my way to becoming one of the elites. If you are sick of getting burned by IEMs sounding too bassy or thin, or being too colored, then buy these. You'll understand why people say they're almost too affordable for how good they sound. For me, I'm happy enough to say this is my IEM endgame. Also, buy some more filters, or clean your ears, the sound tube is thinner than the stem of a Q-tip. If the IEMs go quiet, it's likely not a defective IEM, it's the filter having fulfilled it's purpose.

SE is great, and you likely already know if you'll like it; XR misses the target
Edit: this is a review of both Etymotic ER3 SE & XR, I had two separate verified purchase reviews up when they were different listings but now they've been condensed into one listing, so I deleted the extra review. TL;DR is that the SE is great and the XR is a 'nice try' but I wouldn't recommend. SE - 5 stars XR - 3 stars Was curious about the halfway point between ER4s and the HF line, so got both the ER3 SE - Etymotic's hallmark flat sound - and the XR, with enhanced bass response. They're both in between the HF3 and ER4 in build quality. The cord's not as durable as the threaded ER4 cable, but it's a lot sturdier than the HF3's (which WILL fray within two years, the big problem with those otherwise great IEMs). Curiously, the cord on the XR was a full foot longer than the SE's, though otherwise both products are identical. Like with the ER4, the earbuds themselves can be easily detached from the cable, in case you need to replace a damaged cord. Dealing with the cord is a necessary hassle. It lacks a mic or audio controls, but there's a clip about where those controls would be, and you'll want to fix that on something high on your body to reduce cable rubbing noise, which is extremely pronounced. The cable microphonics are so bad in part because the passive noise isolation here is unsurpassed (true of just about all Etymotic IEMs), and without needing any suspicious tinnitus-flaring/ear-pressure-popping, pricetag-inflating active noise canceling tech, either. With a good seal, the outside world is closed off as effectively as with professional musician's plugs. I use Comply foam tips (just don't like the included plastic phalanges, YMMV) and can regularly wear these for hours (obviously being conscious of overall hearing exposure; one benefit of excellent noise isolation + terrific sound reproduction is that you can listen to stuff at a lower volume). Fantastic for commutes, plane trips, working in public, whatever. The earbuds stick straight out, so they're not appropriate for anything with your head sideways against a surface (like laying on your side resting or doing yoga or something). These aren't as fussy as the ER4 about wanting a preamp from many mobile devices, so you can just slap these into anything. But like other Etymotics they'll badly expose poor audio sources/low quality recordings. And if you want a really bouncy sound, or if you're playing from low-quality sources, you're in the wrong place. Etymotics deliver uninflected, unembellished, accurate sound from good sources/recordings. You probably already know if that's what you want, and if it is, the ER3SE delivers. Get it and be merry and save several bills off messing with ER4s plus amps. Find the right eartips for you and there's nothing else that does a better job of muffling everything else while delivering clarity. Giving up the headphone jack wouldn't be nearly so hard if not for the ER3/ER4. I'm confused by the XR though, and wouldn't recommend it. Etymotic's whole thing is flat, accurate sound. The XR's clear pitch is at people who want accuracy, but with more musical, punchy bass. And so much music is EDM or hip hop, so it makes sense to cater to that. But rather than sounding to me like "Etymotics but with punch" this just sounds muddier (rather than cleanly punchy), and clouds the appeal of Etymotic at large. I understand taking the shot, I just think it misses. If you want punchier, bouncier sound, just about everyone else does that, including the (slightly cheaper, lower quality, but with a mic and in-cord audio controls) HF3. If you're here because you already like Etymotic already or because you're looking for very good, accurate, inexpensive headphones, get the SE. I listen to all kinds of stuff, from classical to rock to rap; I've run a lot of hip hop with quality production through both the XR and the SE (Run the Jewels, Cannibal Ox, Aesop Rock, DJ Shadow) and I just don't think the XR does what it's claiming. I'd rather just listen to well produced hip hop on the SE anyway and appreciate other aspects of the music and accept that Etymotic isn't the place to go for the car-rattling-bass type experience, or to listen to someone like Emika. Lots of ppl like the XRs, maybe it's just subjective taste or maybe it's like the cheaper plasma TV looking inferior next to others in the store, but amazing all by itself in your home, but I wrote this for anyone curious about a direct comparison between the SE and XR. Why not the HF3? It's also very good. But if you use it regularly, it's also guaranteed to fray. The cable is noticeably lower quality and not modular. To their credit Etymotic's service is great and they have a lower-cost replacement program for damaged headphones. But probably make the jump to a much higher quality product that won't fray and is fixable if it does unless you need mic/controls on the cord. (Obviously it's nice to just answer a call if it comes in while you're listening to stuff on your phone, which is why I also have had several pairs of HF3s, which is how I know they're definitely going to fray eventually.)

An Excellent Tool - Not Good IEMs for Most
Firstly, these are a tool and are designed for work. For hearing protection where you need or want to listen to something, i.e. live performances, listening while drumming, music while mowing the lawn, hearing protection while flying in a plane, they are excellent, but I do not recommend these to most people outside of those situations. They are indeed accurate and sound okay for what they are, but never in my life would I use these for mixing or listening if I had other options. At their price, you have MUCH better options for sound and detail. Again, these are a tool for a specific purpose. Specifically, their frequency response is 20 Hz to 16 kHz, and that should tell you all you need to know. 16kHz is the highest frequency of FM radio, so needless to say these are not detailed and have no 'air' since CD audio and even most MP3s have sound up into about 22 kHz, with of course Hi Res audio going far beyond that. Many reviews state these IEMs sound close/intimate, flat, and dry. This is only partially caused by the fact they are a tight seal deep in your ear, but is mostly caused by the lack of high frequency detail that cuts out reverb and other sounds. The rolloff is extremely noticeable to me (musician and audio mastering engineer), but I think even casual listeners will feel it even if they can't describe it, as other reviews indicate. As for the package itself, it is very nice. It came with a nice carrying case, tips of different sizes, and even a bunch of double-flange tips that were not advertised anywhere on the listing. Be sure to try several tips, the default ones are TINY and didn't seal for me at all, instead pressing way too deep in my ear. Some may have issues with them being uncomfortable, but as someone who frequently wears similar hearing protection they are totally comfortable. And on that note, they do an excellent job at what they do- Passive noise isolation! When used properly, these will protect your ears and let you listen to some tunes or a click track at the same time. They seal out a ton of noise, and I am happy with the purchase. 5 stars, but would not recommend to most people due to their price and niche.

Shy of discontinued ER6i isolation, however work OK for motorcyclists with custom tips.
After trying a few other isolating earphones I am sticking with my Etys, which are the closest to the sadly discontinued ER6i, which first drew me to this brand. Unfortunately, nothing on the market now performs as well, as ER6i in the sound isolation department. However the newer ER models come close with carefully cut third-party tips. 90db road wind noise (at speeds over 90mph - on the race track of course, as a law-abiding citizen like myself would never exceed a posted highway speed limit) puts somewhat extreme requirements for isolating earphones. Why the isolation in our age of advanced electronic ANC? Because the latter doesn't come close to silencing the main enemy of biker ears: the wind noise. I've tried the best ones like Sony LInkbuds S (forget your typical mediocre Airpods Pro). They do very little even with long foam tips. It was tempting to look for triple-flange ones (see below on foam tips in general), but why try to fix the weak ANC at all? Instead of proven passive sound isolation. No miracles about foam. One reviewer here praised yellow Shure tips, which I also tried. I don't think it's the shape of my ear canal. All mentioned by him "Ety diehards" (yours truly) do have a point about the triple-flange tips. In all my experience: trying the supplied foam tips with the ER6i years ago, and similarly with this ER3SE: both the ones that came with it, and the old ER6i ones, the isolation was dismal. There was no revelation with the suggested yellow Shure tip either. Foam doesn't block the noise, period. I wonder where 30db NRR ratings come from. Plugging a perfect hole in the wall instead of a real human ear? The longest I found: Comply P-Series tips do block some wind noise in a full-face helmet, however like all foam ones, not enough to my liking. Now to the triple-flange tips. BTW forget about double- and single-flanged ones. The included ones are only good for making spacers to use with old gray triple-flange ones from ER6is. What about the better looking translucent tips, that came with ER3SE? Here's the huge design flaw of the newer ER series vs. the tiny ER6i from 15 years ago. The earphone body stem is too long and wide, causing severe pain, when inserted deep in the ear - necessary to block the outside noise. Shure SE series have the same diameter pipe with one crucial difference: the tip itself has a longer stem, so only the soft silicone goes into your ear canal. Not the hard plastic wrapped with silicone. You may have high pain tolerance and try to insert those things deep, especially wet. Which brings another word of caution: don't lick the tips in a classic Etymotic manner. It's a recipe for middle ear infection. Don't ask me how I know. I use water now. And that (a week of crackling sound in your inflamed ear canal) is the best case scenario. If you keep ignoring the pain, hoping that your ears would widen inside (also suggested by some), you are going towards Positional Vertigo (aka BPPV): spinning head when changing body position - due to the damaged vestibular sensors located right there, by your ear drums. Again, don't ask me how I know. Luckily BPPV can be cured with a simple at-home physical therapy (Epley maneuver) all by yourself. I know, the determination to make ER3SE work like my old ER6i did. It wasn't until I tried Shures, that I figured out an acceptable solution: the longer triple-flange tips. I also tried Shure's own white ones, and for whatever reason they isolate well only on one model (SE425). Not almost identical size-wise SE215 (which sounds better than a more expensive 425 IMO), and not Ety ER. But longer-stem "Almond" tips did the trick. FWIIW get them (see ASIN in the pic) instead of (also long enough to cut) Shure tips. Or get both, cut the right length, and compare. Other than the isolation issue, ER3SE sound way better (enough bass and crystal clear highs) than the old ER6i, and also better than Shure SE215, let alone more "professional" SE425 - at least to my non-musician ears listening mostly to EDM. I just wish Etymotic brought back their unique ER6i, that could block ANY noise. It'd be nice to offer short "helmet-only" cord. One more tip on inserting the tips. Unlike the ER6i, when the deep (and painful) insertion rewarded you with more isolation, these ones just cause pain. Unfortunately the outside sound can only be muted to a certain degree in my ears (consistent with slightly less isolating Shure 425s).

Great Sound - False Advertising
With the Comply P-series tips they sounded amazing and were very comfortable as well. A surprise considering how far in your ear they go. However, when to attach it to a MMCX-2.5mm balanced cable I discover that contrary to what Etymotic says (detachable cables with 3.5mm Gold plated stereo Plug and MMCX connectors), this does NOT use MMCX connectors which according to the MMCX specifications has a "lock-snap mechanism allowing 360-degree rotation." Instead, they use a proprietary system based on the MMCX, but with an added tab-notch mechanism designed to stop 3rd party cables from being used and forcing you to purchase Etymotic's own cables at a high premium (cable replacement is 2/3 of the cost of the product itself). Then someone (Etymotic/Amazon?) saying "Due to sanitary reasons, this product can not be returned when opened." This is why there are laws governing advertising and this one isn't up to snuff. Just SAY it has a proprietary connector so people can make an informed purchase instead being deceptive and having the customer only find out after he's locked into a not inexpensive purchase (from $100 to $400) that he has to pay $40 for a standard replacement cable ($60 for the balanced) instead of one of the many 3rd party cables available, some of which can be had for under $10. Standards like MMCX exist to make sure everyone knows exactly what they are ordering or discussing and must be used that way. I mean, say you ordered a standard electrical extension cable from Amazon. When it shows up it has 6-inch-long prongs and would leave 5 1/2 inches of live current sticking out of the wall. The seller saying well they fit MY outlets which has 6-inch-deep holes. Nope... not the way it works.

Bought to use with arcade music games. Amazing fit & isolation, and excellent quality.
I was using a less comfortable pair of in-ears before, but I decided to get these when I found out my arcade was getting a beatmania IIDX lightning model. I'd be playing it a lot more than other cabs with headphone amps, so I wanted something I'd enjoy using for longer periods. On a busy Saturday night, literally all I can hear is the game I'm playing. It doesn't even need to be turned up loud. Screaming kids, crowds jumping on the Pump It Up cabs, noise from other machines, are all inaudible. It's awesome! They're saving my ears a lot of fatigue since they don't need to be turned up loud at all in order to sound good, or to isolate noise. They've made a massive difference in how much I enjoy myself playing for a long time, and my ears aren't ringing by the time I'm done. I had Klipsch headphones before which didn't stay in very well, so while they weren't /uncomfortable/, it was very distracting to need to constantly adjust them, and doubly so if one began to slide out while I was in the middle of a song. The etymotics are very comfortable, you can have them in for quite a while and forget they're there. Obviously arcade machines don't have the world's greatest headphone amps, but for my use case these are fantastic. I've tested them at home on a Monoprice tube amp/dac (they don't make it anymore so I forget the exact model) and they sound quite good, though they did sound like it wasn't the right amp for them either. They would probably sound best with something nicer. Because they're very sensitive, there's virtually no volume ceiling on any of the machines I play. So if I do want to turn it up, that's no issue. These are the flat frequency response version. For my case the bass boosted ones might have been better, but flat response is more universal in my opinion (and the IIDX cab has built in equalization anyway; useful!) They certainly hit bass with no problem, but you can tell that it's dialed in flat, so it's not boomingly bassy unless you EQ it that way. For people who don't want to fuss with it and don't necessarily have mixing or audiophile needs, the bass boosted version would probably be worth considering. They were packaged nicely and included a case, but the soft material of the case's interior seems to shed plastic fibers with little provocation, so I got a different one (don't want those in my ears.) My old Klipsch pair have a tangle resistant cable which I didn't fully appreciate until I got these. Since the cables are interchangeable, that would be a nice feature to add!

Come for the amazing sound quality, stay for the outstanding usefulness as travel headphones
I bought these largely out of curiosity, knowing that the Etymotic ER series is famous for their extremely accurate sound reproduction. Having full sized Sennheiser and Hifiman models, I didn't necessarily expect their sound quality to be comparable, especially at this low price, but it absolutely is - maybe even better. I won't review their sound other than to say that they sound really incredible so long as you don't expect bass cannons and can deal with middling soundstage. What I really didn't expect was for these to be the best travel headphones ever - I'll take these over any Bose or Apple noise canceling headphones any day. They may not have active noise cancelation, but their passive isolation blocks out sound way better than any of the active noise canceling headphones. Having a 3.5mm connection, they're easy to plug into a plane infotainment system. They take up no space - you'll appreciate the extra space in your bag - and while they may feel strange and uncomfortable at first, I find that I have completely gotten used to them and can wear them for hours with no discomfort (like full sized headphones) or without them coming loose (a problem which plagues me for most in-ears). You can easily sleep with them in and use them with a neck pillow. In other words, they pass all the tests for travel headphones with flying colors, as long as you can deal with the fact that they're cabled - a slight annoyance, but even that has its benefits in that you needn't worry about the battery dying. I have a lot of headphones, earbuds, and IEMs. They all have their own uses and signatures, but for me, this would be the desert island pair - the ones I would take if I could only have one. Their compact size, world beating sound isolation, and pristine sound quality make them useful for almost any use case.

If you have narrow ear canals, these earbuds are torture!
I didn't realize that the earbuds had to be stuck so far in the ear canal! It actually hurt my ears to use them! If you don't stick them in far enough, the bass is tinny, at best. The rest of the sound reproduction is fine, but I like the bass to be equal to the other frequencies. I can see why this company sells a line of product that boosts the bass - it's practically impossible (at least for me) to get a good "seal", and a good sound, but I'll keep experimenting. I'll probably end up sticking with my Bose earbuds. I wouldn't recommend this product for older folks like myself - out ear canals tend to narrow with age.

Ottimi auricolari dal suono naturale
Come da titolo per me che ascolto musica prevalentemente acustica hanno una risposta neutra su tutta la gamma, buona la dinamica compatibilmente con le piccolissime dimensioni Per farle cantare bisogna trovare gli adattatori giusti per le proprie orecchie cioè quelli che meglio ti isolano dai rumori esterni, forniti comunque in dotazione. Attenzione al volume di ascolto perché arrivano molto vicini al timpano.

Etymotic hits another one out of the park
Etymotic makes great in ear monitors. This is my third set, and I am very impressed. First of all, the previous ones - I forget the model number - did not have replaceable cables, and the cables frayed at the attachment points, so into the bin they went (this was after several years of service, so I'm not complaining too much). Big kudos to Etymotic for making these replaceable. Second, the new tapered silicone tips that have only two flanges are much more comfortable for me than the three-flange originals. In my ears, the three-flange version gets quite hot and itchy and it's hard to concentrate on the music when that happens. The two-flange version removes that problem, without seeming to impact either the sound quality or the noise isolation. Third, all the good qualities are still there - great sound, great isolation. While I don't find in ear monitors as comfortable as my HiFiMan 5xx or Sennheiser 6xx, having the isolation on say a long air trip makes a huge difference. Plus they fit in my shirt pocket. As for the sound, I would say the Etymotics emphasize slightly the mid treble. Exceptionally good for classical music but some older poorly equalized rock (Led Zepplin I'm looking at you) can sound a bit more thrashy than what I consider normal. As for the low end, some people prefer the similar XR version but these have plenty of bass for me. These have replaced my Shure SE215 as my travelling IEM. The Shures sound fine but again a bit emphasized in the treble. But they don't isolate as well and the housing presses against my ear and becomes uncomfortable after awhile, whereas the Etymotics don't cause any of that kind of discomfort. Highly recommended.

Well worth the extra pounds
I have had several Etymotic earphones in the last 14 years Started with ER6i EMRK 5 And now these ER 3 SE Started with the Adventures Broken land Then Carleen Anderson maybe I'm amazed Such a deep base tone the treble is sharp and toned down The guitar and Piano come through perfect Nice purchase and with the 2 year warranty should provide me with many years of listening enjoyment

Great sound, well made, comfortable
Only got these this morning so it may be too early for a review, but so far I'm really happy with them. I usually find earphones to be quite uncomfortable, but these fitted with no problem and did a really good job of cutting out extraneous noises. They're well built and well thought out. I like the fact that you can replace the cable so easily. It's my first pair of true in-ear earphones and I'm pleasantly surprised at the quality. The sound stage is great, making the sound intimate for intimate settings and large for concert halls. Very pleased so far and looking forward to using them a lot more.
