Review: Excellent Product - I have one tiny complaint about these. I wish the manufacturer had used better cable so that they were completely tangle free. It is better than what we've got used to over the years, much of it cheap and nasty but for a bit more cost, these would be spot on. I've looked at all sorts. I definitely wanted wired earphones, there's enough aggravation having to charge loads of items without adding expensive Bluetooth gadgets to the list. These are comfortable. I'm fine with the medium pads but there is a smaller and larger set included. A very handy bag with a sprung top is a good addition. Now for the main reason for the five stars: the sound is excellent. Clear and detailed. I've noticed quite a few times with some old earphones I've been using on an MP3 player at the gym that distortion was mysteriously occurring. It was noticeable with some of the Who recordings where the guitar does some accented power chords. Today, clear as a bell. The studio effects of reverb and delay which are present on most recordings were likewise very clear and precise. On today's random playlist was some stuff by Earth Wind and Fire whose studio records are brilliant recordings. A completely different style of music came over really well as did Chick Corea playing Spain. I've got all sorts of expensive music recording gear at home so have a decent idea of what is possible to achieve soundwise in terms of quality. These are surprisingly good.
Review: ... these in-ear headphones for a month and I'm really happy with my purchase - I've now owned and used these in-ear headphones for a month and I'm really happy with my purchase. I bought them because I work in an office with a single communal lunch room and I like to study while I'm having my lunch. It's so noisy you can hardly hear yourself think so I tried using a pair of Apple in-ear headphones and combined it with a white noise app that bellowed the sound of an air conditioner into my ears. It was useless as I could still clearly hear the racket around me so I tried my luck on a pair of Sennheiser CX300 II's and I'm so glad I did! These headphones are fantastic for reducing the external noise as they fit inside your ear canal using the supplied rubber fittings. Three different sizes are supplied (small, medium and large) with the medium already attached and this fits me perfectly. My wife has very small ears and the small size fits her ears well. Next, the sound quality is surprisingly brilliant for any application, a good range of base and very well balanced. If you like listening to music with lots of bass or like to listen to podcasts you'll be equally satisfied. The build quality I would say is very good too, no problems in that department and I'm very happy. 2 year warranty is supplied so I'm sure all will be well in case of a fault. It comes with a small pouch to keep your headphones in and that's a nice touch. Just to balance the review with negatives; I find my headphones are always tangled up when I take them out of the small pouch, no knots but I have to spend a minute to untangle them every use. Also the design is the right headphone lead is much long than the left, rather than both being the same length to the join. It means you could plug one ear in or loop the right lead round the back of your head. I'm not a particular fan of this design but that's a personal preference and I can see the benefits. Just to sum up - quality in-ear headphones, very comfortable to wear for extended use and amazing all-rounder sound. Can't go wrong at this price.

## Questions & Answers

**Q: What is the difference between Sennheiser CX 300 II and Betron RK300 ?**
A: I don't know the Betron, but I own both the SoundMAGIC ES20 and E10 and they are better built than the Sennheiser.  SoundMAGIC cabling is really well made and the earphones themselves are constructed from aluminium.  The Sennheiser's feel a bit cheap and plasticy to me.

**Q: Do they come in the manufacture case as it would if I were to buy it from a store?**
A: Yes it comes in a plastic casing which is very hard to get into lol

**Q: How do you adjust the length of the wire for each individual headphone once they split off?.. The left headphone is far shorter than the right one**
A: Hey Sam, sadly you can't. The idea is that the longer wire goes behind your neck. It stops the headphones getting in the way. Hope this helps.

**Q: Do they leak noise? Being in ear I am hoping they wont. Please help!**
A: Well, if your playing your iPod on full volume without them in your ears, you'd be able to hear the music. But when worn, the sound of anything around you is about half as loud, maybe less. This means you don't have to push the volume much in order to hear NOTHING but your music, at 50% vol you can't hear anything going on around you unless in a "louder-than-usual" environment, I think at 60% ish you get more of a crisp! full sound! anything above that really isn't needed unless your hard of hearing. I've noticed more in the music I've listened to before with these phones so I'd say they keep the sound in your ear when worn, this is possibly supported more so by the fact that half as much sound gets in from the outside.I'm sure anyone who isn't an audiophile who wants best of the best would be satisfied with these earphones, they are better than anything similar for the same price, in my opinion.

### ⭐⭐⭐⭐ Great for the price
*by V***C on 20 May 2017*

This is the third pair of these we've bought in the space of several years - one each for my partner and I, and this pair being the first time we've had to replace them. As a more affordable pair of Senneheisers, these work great. Sound is clear and high quality, although note these do boost the bass a bit, so if you're not a fan of that you will want to adjust the equaliser settings on your phone. They work great for cancelling outside noise as well - I sometimes wear them at work just to reduce the ambient noise around me, and they do an excellent job of blocking out awful political discussions in the office! There are some negatives. The asymmetrical length for the cables is supposed to enable you to wear these with the device in a pocket, and reduce tangling. In my experience, the longer side is far too long, loops awkwardly and catches on clothes and limbs and therefore tends to send a lot of *rubbing against stuff* noise up the cable, and this also makes it more prone to tangling rather than less. But overall, for a £23-£30 pair of earphones that seem to last a good 18 months or more of *heavy, continuous use* you really can't complain. We never kept them in the little bags they come with, they were often roughly handled in and out of bags and pockets, and more than once I've dropped my phone with the earbuds in my ears, resulting in the cable getting tugged out of the jack. And yet it took this long for the first pair to need replacing.
