CX True Wireless Earbuds - Bluetooth In-Ear Headphones for Music and Calls with Passive Noise Cancellation, Customizable Touch Controls, Bass Boost, IPX4 and 27-hour Battery Life, Black

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.

I recently lost my AirPods on a trip and was looking for something to replace them. I didn’t want to pay what they wanted for the AirPod pros and I wasn’t really impressed with the sound quality of the AirPods, so I went looking for the best sounding sub 130$ wireless earbuds I could find. I settled on the CXs and received them today. I’ll get to the sound quality at the end but first let me go over some other aspects. The set up was extremely simple, there are clear directions, I just pulled them out of the box removed the very obvious and labeled plastic covers on the battery contacts and then charged the earbuds for about an hour. Once they were charged they paired with my iPhone no problem I also downloaded the app which worked without issue. The fit is slightly less comfortable then the AirPods however they are not uncomfortable and feel quite secure. These buds lack ANC however I don’t think that will be an issue as they are very effective at blocking outside noise. The touch controls are intuitive and work smoothly. So far I have used them both together and one at a time and have taken them in and out of the case and have no issue with connectivity, you do have to reconnect to the app if you disconnect from Bluetooth however the app does have to be running for the earbuds to work, only if you want to run the equalizer also reconnecting to the app is very simple. The only “issue” I have had so far is when I updated the firmware; everything went fine however be prepared to have your phone and earbuds tied up for about 40 minutes while the firmware updates; during this process the app needs to stay open and the earbuds need to be close to the phone. It’s a little nerve racking because I was worried if for some reason the update was interrupted it could brick the earbuds, that being said it went fine just took a long time(the app does give a fairly accurate countdown so that helps a little). So how do they sound? There is no doubt these are the best sounding pair of earbuds I have personally heard in my life. I’ve owned the AirPods, the Jabra 65t, first generation beats, and a couple different Chinese pairs; none of those are even in the same category. These where the first earbuds I’ve had that do not sound like music is just being pumped into my ear canals; the music sounds like it’s naturally coming from the surroundings. Every instrument and vocal track are clear and separate. The bass and treble sound great and balanced and if you really like pronounced bass you can turn it up in the equalizer and it thumps. It’s really hard for me to overstate how awesome the sound is, I listened to a few songs that are now in lossless Dolby atmos on Apple Music and it’s nothing short of incredible. The best metaphor I can think of is all of my old earbuds were like Standard definition and these are 4K. So if your looking for the best sound for your money and probably the best sound for under 200$ these are the way to go.

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.

Edit: originally rated 1 star as the earbuds that I received were open-box/used. I don’t think it’s fair to Sennheiser that my 1 star rating remains on here because that was a fault of Amazon. These earbuds sound great. Absolutely great. The connection seems to be good so far as well (I’ve seen a lot of negative reviews saying otherwise). They are very comfortable for my ears, I’m a Tool Maker/machinist and wear an earbud in one ear I all day and other earbuds that I’ve tried get uncomfortable or start to fall out but I have had no issues with fit at all. As far as the features on the app: the equalization is only a 3-band eq which is a shame, I’d much rather at least a 5 or 7-band eq but it’s better than nothing for sure. The side tone feature is supposed to use the mic to feed into the speaker, allowing you to hear outside talking, but it doesn’t seem to really work at all. I haven’t tested a phone call using them yet so maybe my mic is defective but I really wouldn’t care because I don’t need it. Overall this is a great pair of earbuds for the price. Original review: This item came in with the packaging already opened with another piece of tape over the original seal. The earbuds were covered in earwax and ear hair. Disgusting. If I wanted to buy an “open box/used” I would’ve selected that option instead of paying full price for it. Edit 3/14/2023: it's been 8 months and the connectivity issues have been becoming a decent problem. I take them out of the case and they won't connect, so I put them back it and take them out again and usually they'll connect after the second try. But lately I've been having to re-pair them to my phone. I'll take them out of the case and instead of the usual "power on..... connected" notification, it's just silence. And it's not as simple as just re-pairing them because they won't go into pairing mode unless I reset them. The battery life is also taking a dive. I started out really loving these, now I've been very disappointed because they're just such a hassle to deal with. With all of this, especially only being 8 months of use, I'm going to have to update my review from 5 stars to 2. Edit 7/17/2023: the right earbud just stopped working all together, it'll power on but refuses to connect to Bluetooth Edit 1/24/2024: I've been trying to get as much use out of these just to justify the amount I spent on them before I replace them but all it has really given me is issues with connectivity and reliability. I expect any earbuds at this price range to last years, I should have no problem getting the same life out of earbuds that you would expect from a phone. I wish I would've just either returned them or thrown them away a long time ago. I'm going to start looking into replacements now. Adjusting my 2 star rating to a 1 star.

I have a pair of CX's that are about 1.5 years old, and another set that I just recently purchased. In the middle, I have a pair of Momentum TW 3's that are ~6 months old. The TLDR here is that instead of repurchasing the Momentum, I got another pair of the CX's. I'm not an audiophile, and I mostly listen to audiobooks and make calls with earbuds, so I'm not going to be speaking to audio quality at all. For me, it's fine. My six month old Momentum's have a dead left earbud. Possibly this is anecdotal, but if anything I was more gentle with the Momentum's than the CX's, and the CX's have lasted three times as long. Yes, I drop them. Yes, the dead left Momentum died after the most recent drop. I'm not saying that earbuds should survive infinite drops, but in my experience, the CX's are more durable. I did really really like the ANC on the Momentum's. It killed the battery life, but when you need ANC, it was great to have. The pass-through audio was also awesome. It was almost like having a mini-hearing-aide. The CX's have been substantially less finicky than the Momentum. They connect quicker, I've had to reset them fewer times, and they seem to have better range. Between the (substantial) difference in price and the areas where the CX's are superior, I my opinion, the CX's are the better option. If dropping $150 every six months on earbuds is within your budget, I fully endorse the Momentums. For me, I need to have two working sets around at any given time as I wear them a substantial amount of my waking hours, so I'd rather swap to an overear model when I need ANC and go with the cheaper and more durable option. Quick recommendation -- splurge on the foam eartips. If you're like me and wear earbuds an unhealthy amount of time, they're substantially more comfortable. They do wear out, and they're not cheap, but the added comfort for long-wears is huge.

I've owned a few pairs of earbuds, all wired. I prefer over-ear headphones, but needed something small, portable and more discreet for work. These looked decent and my past experiences with Sennheiser sound quality also helped make my decision at the time. Sound quality is excellent, overall noise isolation is pretty good for no ANC, bass mids and highs are all present and clear. I do own several pairs of studio/reference headphones, which these obviously don't compare to, but they do manage to make a good account of themselves. Battery lifespan is excellent too and despite no wireless charging (not that it was a deal breaker in my case) the case charged very quickly. Just would have been nice if the charging cable was longer than the dinky one supplied. I used the smallest set of ear cushions, these are decently comfortable for up to a couple hours but do start to press against my ears for longer periods. Construction quality of the case and buds is decent, not too heavy but not feather light either. It's a shame that doesn't go into the internal electronics. First off, the Bluetooth connectivity is not a win. These would repeatedly disconnect themselves when bringing them out of "sleep" always one or the other bud. The Sennheiser Smart Control App does allow customization of the buds controls and a graphic equalizer. But it would keep proclaiming it needed a update, even though it was the most up-to-date version. Now these, when they paired, sounded great. After using these for nearly a year, the right bud suddenly had an internal fault and produced flakey, weak sound. That was not a Bluetooth issue, but rather the hardware either failing on a circuit level or a wire becoming loose due to a cold solder joint. I've owned plenty of headphones that are more cheaply made than these with worse sound quality but still function as intended. Looking up this problem seems to be inherit with the CX True Wireless, with complaints occuring anywhere from a few months of ownership to nearly a year or more. Replacements from Sennheiser have been described as having a repeat issue after a similar period of time, or are merely DOA. Shame, this isn't the Sennheiser I knew. Time for a different pair from a different manufacturer. Why bother going through the hassle of dealing with Sennheiser support only to get the same problem again eventually?

Bought this in 2021, I am still using this now in 2026. The earbuds often great sound. I bought some foam ear tips to make the fit even more comfortable.

I've bought two pairs of these. The ones that I'm now looking to replace I had for 3 years and 4 months. Both pairs worked until the right side ear bud just stopped working. Same problem with both pairs of earbuds. I replaced the first pair, which broke even sooner, because the sound on these things is GREAT. Pretty amazing fidelity for bluetooth earbuds. But with the durability problem the fidelity comes at a pretty high cost.

Ya tiene un poco mas de un año que los compre y siguen funcionando bien. Le puse una funda para que tuviera una protección extra ya que por su tamaño es muy fácil que se te puedan caer si no los agarras correctamente. En las fotos que subí esta con la funda, la cual naturalmente no esta incluida en la compra. Los uso principalmente para escuchar música en el celular y la computadora, también los he conectado a la salida de sonido de la televisión y prácticamente no se siente retraso de voz. En una ocasión me pasó que solo uno de los auriculares se conectaba y el otro no, pero en la pagina del fabricante menciona como se puede hacer un reset para que vuelvan a sus valores de fabrica y con eso ya volvió a funcionar correctamente. Los bajos se escuchan bien y el audio en general es muy claro. No los uso para hacer llamadas, así que en ese punto no puedo opinar. En resumen son unos audífonos muy buenos y a precio competitivo.

I ordered a pair of Sennheiser CX True Wireless Earbuds after a bad experience with another manufacturer which I won't get into here. The Sennheiser CX Earbuds had a very easy set up. After opening the case and removing the plastic strips from the buds I charge them for a couple of hours before trying to do anything with them. Once they were charged I took them out of the charging case and changed the silicon tips to the large version which I always have to do. I tried them and they fit perfectly. I previously had downloaded the Sennheiser Smart Control app on my phone and as soon as I opened that app it searched for my CX Earbuds and found them without any issue. A pop up on my app asked if I wanted to pair which I of course did. I opened up some music and started playing it on my earbuds without any issue. The app is simple with a very simple EQ but it works well and I had no issues with it. The sound through the Sennheiser CX earbuds is great. I have not taken any calls with them up to this point. I probably will in time but I bought these strictly for the sound quality so that when I travel and fly I have a no-nonsense listening experience and without being wired in to my phone. I have always found that with my different earbuds that I have had very good passive noise cancellation so I am not worried about these not having ANC. Especially at the volume that I typically listen to my music at. So in conclusion. There were extremely easy to setup and the sound is very good and with good Base. The sound of these is supposed to be comparable to the more expensive Sennheiser CX Plus and Momentum 2's but with fewer options. I can't comment on that but these are great and I am very happy with my experience so far. I should mention that I did take another pair of silicon ear tips and put them on the Sennheiser buds as I find they fit better in my ears than what Sennheiser sent with the earbuds.

Good

Ich habe diese Kopfhörer rücksichtsvoll benutzt, aber nach einem halben Jahr funktioniert nur noch eine Seite und die andere hat einen Wackelkontakt, wo die Soundqualität oft mies wird. Einfach nur erbärmlich

Stock out of the box sound is a typical, slightly veiled, warm Sennheiser sound but with a touch more bass. After updating the firmware from the Sennheiser app, use the "sound check" function to create your preferred sound using your favourite music playing. For me, the sound check equalisation pushed treble up about 3db and cut bass at about 2db. The earphones now become much clearer, cleans up the sound and bass less boomy. I do enjoy fidelity of the sound, the drivers can handle bass very well, with podcast EQ selected, voices become very natural and easy to listen to for your Spotify podcasts and YouTube lectures. Fit is a little large and you need get used to it. Stock eartips are a little stiff, and needs time to soften up. Stock eartips are half dome and inserts deep. So no worries about it popping out while doing cardio. Will recommend if you're willing to EQ the earphones.
