Review: Great for the price - I’ve been reluctant to go wireless, mostly because of sound quality issues of Bluetooth. But I really like the idea of being free from wires while at work, I already have phone/meeting headsets that are Bluetooth and love them. These went on sale Cyber Monday for a good price so I thought I’d try them. I found them a little bit of a pain to setup. The “Quick setup guide” was lacking information. Once I downloaded the full manual I figured out what I was missing and then got them setup and working with my phone. Sound is very clear and bass is excellent and not muddy. It does take a little tweaking of the EQ in the Smart Control app. Noise cancellation is very good considering its passive. These are generally comfortable but can cause a little fatigue if in for long periods. I’m in and out of meetings everyday so generally this is not a problem for me. I have found that I cannot position them the same in each ear. Everyone’s ears are different but unfortunately the only way to know is to try them. Battery life is good, though I stick them in the case when I leave my desk and the charge tops off on its own. Being Bluetooth, they do drain my phone a lot more than wired buds. I can’t comment on failed bub issues yet, it’s too early, so we’ll see. I didn’t intend for these to be used with phone calls but ended up taking a few calls while wearing them. I was surprised at how good the voice sounded. Warm and no distortion. The person I was talking to said it was pretty good. She had no trouble hearing me. A few complaints in the reviews I noticed of which have fairly simple solutions. 1) Lack of bass. Make sure you are using the correct size ear adaptor and that it is snug in your ear. This is critical. They have the medium on out of the box. They seemed fine, but after a couple of days I took a chance and tried the large. Wow, dramatically better. I also found you have to wiggle it just a little to get the maximum effect. Also download the Smart Control app to get a bit more bass from the EQ. I suggest trying the Sound Check component of the app. 2) For the units that are prematurely dying, I wonder if the contacts are dirty. The full manual specifies they do need to be cleaned from time to time. Also, they do have a 2 year warranty but you have to contact a Sennheiser partner. EDIT: I mentioned above that I got a little fatigued with them in for a while. After pulling out a couple of hunks of ear wax with the right ear bud, I decided to try some ear wax remover. Not only do the bud fit better, they are more comfortable. Something to think about if you are experiencing discomfort.
Review: Still loving my Sennheiser earbuds! - I love my Sennheiser earbuds. I love Sennheiser products, I started with their amazing microphones. I have been using my sennheiser earbuds for almost 3 years now and I never had any problems with it. The audio is clear, the music is crisp. It sits comfortably in my ears. I had several rubber attachments to choose from. It is very easy to use and to connect to any device. I still enjoy using it very much.

## Questions & Answers

**Q: Are there better that the 400bt true wireless ?**
A: With Sennheiser sound is the #1 consideration and both the CX True Wireless and CX 400BT True Wireless provide amazing sound quality so either is an excellent choice for sound.

The CX True Wireless does offer a few additional features:
1) Bass Boost ... so you can get your music really pumped up.
2) Role Switching ... so you can use one ear bud at a time or both together.
3) Adjustable Sidetone ... so you can hear your own voice during calls.
4) Smaller ergonomic design ... so you can get a more snug fit in the ear for great passive noise cancelling.
5) 27 hour battery life ... so you can have your music all day.

Have a great day.

**Q: On the underside of the earbud there is a small piece of material over the charging contacts. What is this for and should I remove it?**
A: On the underside of the earbuds there is a protective covering over the charging contact points to prevent the earbuds from powering on before they are ready to be used. You need to remove this protective covering prior to charging otherwise the earbuds won't be able to power on.

Have a great day.

**Q: Can you use just the left earbud by itself?**
A: YES!!! The earbuds feature "role switching" which lets you use each earbud separately or together as a pair.

The added benefits to using only one earbud at a time is that you can hear what's going on around you (ie: if you are walking do the street) and one ear bud can be charging so your music is always ready to go.

Have a great day.

**Q: Does this have a qualcomm chip? if so, which series chip? qcc5100 or 30xx or other?**
A: Qualcomm Apt X

### ⭐⭐⭐⭐ Solid choice for ear buds
*by C***S on December 22, 2023*

I've used these ear buds for almost 2 years and strongly considered re-buying them once I started facing issues. When it comes to sound quality, they're good, and the latency is small, but you'll notice it's there. The best part of these ear buds has to be the battery life; these things last all day, and can be fully charged back up twice with the case. Though if you're looking for something with strong noise cancellation, you might want to consider looking for a different pair of ear buds, as these are really only capable of blocking out most speech. Overall, they're a pretty good pair of ear buds, but I do have a few problems with them. First, when they get to low battery, the text to speech voice will say "Recharge headset" just frequently enough to become mildly vexing. This is my primary complaint about these ear buds. Now mind you, I haven't treated these ear buds very well, they went through constant abuse and were used in sub-optimal environments the entire time I've owned them. The next two complaints are likely a result of my poor treatment of these. Second, after about two years of use, their connectivity isn't as great anymore; the range in which I can use these has dropped considerably. I used to be able to walk in my backyard without issues, but now I can barely leave the room without the connection dropping constantly. Lastly, the left earbud has recently developed a problem with connecting to the case; it seems the leads just don't connect half the time. This occasionally causes small inconveniences with the left ear bud turning on in the case and randomly hijacking the audio output of my pc, or it just doesn't end up charging and I'm stuck with a single ear bud until I manage to get it to charge again. Overall, this is a pretty good product. I'd recommend it to anyone who needs a pair of long-lasting wireless earbuds and doesn't need the best sound quality or noise cancellation.
