    An ideal product for any type of consumer.

    For their money, just top ears. The official application immediately found them, unscrewed the settings as it should for me and was happy. Just endless. If you just need high-quality sound without bells and whistles, then these ears are the best option for you.

    Pros
    • Sound. The sound is just a bomb, absolutely the same as on the momentum true wireless 2, which returned because there were constant disconnections of the left earpiece. Audiophiles will rejoice)) in fact, because of the sound, I chose these headphones and they pleased me 100
    Cons
    • There is no sensor to turn off the music when you take out the headphones. They look like bolts on the neck of Frankenstein's monster))

    Revainrating 2 out of 5

    A bad product, not worth the money.

    Regarding the comfort in the ears, this is true of all headphones. Sadly, unlike with wired ones, modern battery technology does not permit the development of something compact. Therefore, excessive case pressure on the auricle is unavoidable, whereas wired cases can always be selected so that they almost never press. They are all too large to work with wireless. If you've never heard a good sound in terms of sound, you'll love them. Most people don't need more when they go boom-tsyk-tsyk…

    Pros
    • added features and case size
    Cons
    • Sound is soothing to the ears.

    The product suited me, I will recommend it to my friends.

    Pros below: Good and high-quality sound basses are juicy purely because of the sound and took. Be sure to miss the ate and play around with the audio codec as you like. Cons: Ears get tired after listening for a long time. For example, after a movie what a thread. There is a slight noise like rain outside the window, this is when it is paused.

    I was surprised by the quality for this price.

    I took the CX400 for myself, and not True Wireless 2 for two reasons: I didn’t want active noise cancellation and I didn’t like the tasteless black senkh logo on white TWS2. In these headphones, the logo is made to match the style, and there is no ANC. Before buying, I had a question about the frequency characteristics. On Ozone it is indicated: 5-21000 Hz range and 107 dB sensitivity. In the reviews, a person posted a photo in which the 2022 sticker indicated 20-20220 and 110 dB, like on…

    Pros
    • - Good sound - Design - Small case - Discount price 7990
    Cons
    • - Specifications on the site, on the headphones and in the support statements vary and do not correspond to each other - HORRIBLE support for the 2022 branch of the company - There is not enough transitional size of the ear pads between medium and small

    One of the best deals, glad I bought this.

    These are my first TWS and I was satisfied with the purchase, I took it from Dr. Head for 14,500. I compared the sound in the store with the Sony WF-1000XM3 and Noble Audio Falcon 2 and eventually settled on these. For several days I tried to fit them into my ears, because at first it always seemed to me that they sit too lightly and are about to fall out. But in fact, they sit well and cannot fall out on their own, at least jumping on one leg does not contribute to this. I use it while…

    Pros
    • Smooth sound, without excessive bass. In the ears sit securely and at the same time "easy". The charge is enough for a week of use. Soundproofing allows you not to hear the musicians near the metro. The hat worn over does not put pressure on the ears.
    Cons
    • They are relatively large, respectively, have a large case, which is inconvenient to carry in your pocket. Water and dust protection (IPX) not claimed.

    I do not cease to rejoice at the purchase, a very good deal!

    I tried a bunch of different tws (sony, nobel, jbl, 1sea, etc.) and settled on senkhs, because. there is a necessary minimum of functionality, the sound personally pleases me, the characteristics suit me, the price has fallen to an acceptable level (at the start it was 17K, I took it for 8.5K). I use it for the gym and just listening to music / watching YouTube. They connected to the xiaomi phone immediately, without dancing and applications from the manufacturer. After installing the stray…

    Pros
    • The sound is similar to the older model, the price (I took it for 8.5K), only the necessary functionality without a bunch of unnecessary chips that you use for the first three days, and then you safely forget about them.
    Cons
    • I did not find anything that would cause allergies or irritation.

    I was deceived! The product does not correspond to the description at all.

    I am not an expert, for my taste the sound is normal, but the overall impression of the product is disgusting. I was seduced by a seemingly well-known brand and lost. Got pros: Got an unforgettable experience: do not buy Sennheiser products. Charging hold for a long time, well, or I just do not want to use them. Has cons: Let's go. The material of the case pokotsalis and rubbed the original appearance after a couple of hours, and after a week it looks like I played football with them.…

    A great option for this money, I definitely recommend it!

    I am very pleased with the headphones. Sat right out of the box. Stay very secure. The sound is amazing for tws. No worse than simple Senhauser plugs. Listened with sound from different sources. Everywhere the result is very pleasing. Even on a phone without installing third-party players, the sound from Tidal is very good. If you listen to Flac, then it's generally wonderful. Bass for me personally, even a lot. The sound has a signature Senhauser color. The software is completely unnecessary…

    Pros
    • Sound. Landing. Working hours.
    Cons
    • Touch control is a universal evil !

    Revainrating 5 out of 5

    Excellent quality, absolutely not expected for such a price.

    In general, satisfied! The sound is still on a hi-fi level. Don't be ashamed of the sound If you buy for 8k - it's a bomb and you're lucky! They want to listen. The fit for my ear is comfortable, but they are bulky, they can really press, be careful! The earbuds are of average quality. Well closed, rough, pleasant to the touch. There is no wow effect, the feeling that another pair is missing between S and M Nevertheless, I recommend trying them on and listening before buying or taking them…

    Pros
    • High-quality performance, good sound, the presence of software for sound settings, touch controls and other trifles. Bass lovers, you can try to listen to them. Good quality music, digitization of records plays in detail
    Cons
    • HF cuts the ear, it is quite sharp (the jump is visible in the frequency response). Perhaps this is my subjective, but I turned the equalizer through the application and everything began to sound right from my point of view.

    Revainrating 3 out of 5

    The purchase was not entirely successful, there were minor problems in use.

    I had a previous model, they said that the problem would be solved in them, but no, not solved. Its pros: Good sound, simply the best on the market for the money. I haven't tried APTx, it's possible on android, it's interesting to know reviews about it. I have a simple iPhone. Cons below: If you are talking on the phone in them on the street, they do not have a noise reduction system, they are not airpods, so you will be heard about as well as a bus 10 meters away from you. In this connection…

    Do not buy! In-Ear Headphones

    I've heard everywhere that they play the same sound quality as the more expensive headphones in this range, but the sound quality is poor. There is no bass at all! I couldn't enjoy music. The fit was very poor and the battery life was short. The feel of the body and the buds are also very cheap. I've had pairs of $30 headphones that seem to be sturdier and more durable than these. Very disappointed.

    Pros
    • Price
    Cons
    • No Form Required

    Stay away, product doesn't work with app

    Professional fit great, good case Cons Sound terrible, Sennheiser app won't pair with CX 400BT, very low volume, no bass, connection takes 2 minutes with headphones are taken out of the case, I bought headphones, so I use the equalizer and the app, but every time the search for the device cannot find the Sennheiser CX 400BT. Not worth $199 I'm buying JBL Live 300 Sound 100% better sorry Sennheiser. But not too many connection issues for me, especially the headphones not working with the app…

    Pros
    • Always liked
    Cons
    • Not trendy

    Disappointing product

    I have several pairs of wireless headphones that produce very good sound for $. I saw them for sale and decided to give them a try as they are considered to be some of the best sounding headphones out there. I was excited when they arrived, but it didn't take long for that excitement to fade. These were some of the worst sounding headphones I've tried, including several that cost well under a dollar. I decided to leave them on for a while to see if the sound would improve with the burn, but it…

    • Absolutely amazing!
    Cons
    • unreliable

    Revainrating 5 out of 5

    Very very very good

    I was hesitant to buy another Sennheiser because the bass wasn't there, although everything else was perfect. The sound here is perfect. Plenty (even overwhelming bass) if you ask for it in the app, and amazing Sennheiser detail throughout the rest of the spectrum. That's all you get. Amazing sound. They should cost around $150 considering the lack of features compared to competitors in this price range. ANC is meaningless marketing, but information (transparency) had to be in it. If you're…

    Great basic sound with no frills

    The best sounding headphones I've ever used. Wide, very wide soundstage, excellent detail, tight, clear bass. Soft, comfortable mids. The controls are well designed and pairing was easy. Touch the headphone's touchpad for 3 seconds and the message "Pairing" will appear to let you know the connection has been established. You don't have to put it back in the case and take it out a few times to plug them back in like you do with some headphones. Pretty comfortable, although it could be better…

    • Satisfied so far
    Cons

    Great "regular " true wireless headphones

    Summary: Better sound quality than most, cheaper than premium active noise canceling headphones, and always connected. My background is a former audio engineer/musician, so my other headphones are custom quad speaker in-ears. I don't expect this level of quality from a $2-300 wireless set, but I don't accept poor sound quality and I like the relatively flat response. I've tried the Jabra 75t and other cheaper ones before. Units couldn't cope with the sound quality and dropouts. I'm not a fan of

    Pros
    • This is amazing
    Cons
    • Some bugs

    Great sound for slightly uncomfortable headphones

    Let's get the obvious out of the way: these headphones are larger than expected and heavier, partly because of the 7mm driver (like Sennheiser's more expensive Momentum range). but you won't care about size or weight because they just sound so, so amazing. These 7mm speakers really make amazing sound, better than any wireless headphones I've tried and cost around $100 at the time of purchase. it has better "sound quality per dollar" than anything I've tried. But there are some odd design…

    • Weight
