I'll mention sound first. While it's nice that they're already playing the signiture sound profile in the base, the hearing aids still lack a significant bass response. So I use the bassboost profile, which is great for quiet listening to music, the problem arises when you practice, naturally it deteriorates the sealing of the headphone and you lose the power component of the sound, ie bass. so it is advisable that the headphones have a reserve. Even the relatively cheap niceboy pins 3 anc had far more power. But the sound is acceptable. The problem comes with the controls. It has a touch but advanced control, it can be individually programmed in the program which is great, but more importantly it can be deactivated completely, why? Because just a raindrop and they react immediately, showering with them without deactivating the functions in the mobile phone is not possible at all, rolling on the pillow is also a problem, thank God at least for the app. Imagine the traditional problem when the cork is slightly loose and you want to home the handset (and this is why I hate touch functions to death). I have one complaint about the equalizer, one would think that in the bassboost profile the bass gain is not at maximum, why not make a Custom profile with the same curve and then add the bass. Lo and behold, in the Custom profile, despite the identical curve, the sound is thickened and does not correspond to the same characteristic. I think that's the biggest problem. The ANC function works well, however, the noice cancel does not work so precisely (and I took the larger earbuds), on the other hand, in 95 percent of the cases I need just listening, and it is really good, and what's more, I would appreciate if it could be amplified so that I do not have to turn off the music in the store and understand the saleswoman, whether I do not mind that instead of 20 deca there is 30: -). they could implement this within the firmware and that the update via the app is completely seamless. However, even now without music, the listening level is almost as good as without headphones. Summing up, headphones in the price range under two thousand (now in black friday) are still all about some kind of compromise. The earplugs (beware, they are still earbuds, some people can't have earbuds for health reasons) are a one-stop choice for athletes, for the gym and for bed, in short, they DON'T fit, coupled with excellent connectivity that makes it no problem to have a cell phone in the other room, with solid battery life of the headphones and with active ANC I got somewhere below 50% after four hours of use (which is indeed a great performance, I'm definitely not one of those people who listen to music quietly), very hilarious simple software where you can customize the control functions according to your preferences and a certain degree of water resistance, make them a really great choice. I'm only taking a star off because of two parameters. The sound is weak despite the 10mm drivers and there is obvious distortion at maximum volume. The sound seems to be balanced and clear, but there is no room for stronger bass, see the previous description, despite the fact that I am quite demanding on the sound, I am satisfied with the result, as long as the plug is tight (that is, as long as one does not give physical performance), the bass is OK. I firmly believe that 8/10 will suit people without reservation even in terms of volume. The other problem is the touch control, which reacts to everything even raindrops that make you turn the sound down, stop the playback - I had the chance to try it yesterday and in the shower (purely out of curiosity) it was a complete massacre. If it were not possible to disable the features in the app, I would return them. Unfortunately, mechanical buttons have been taken off the market, probably because of the demands on gratitude, etc. and therefore one has to make some compromises.
