SennheiserCX 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

Great music quality and the case is small and practical.

However, microphone is terrible in windy conditions

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’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 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

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.
