My favorite headphones, for me they are the best I have ever had. I prefer this model to the large Momentum 4. Because for me they have a better sound, you can also turn off ANC, which is impossible in Momentum 4. Personally, I never use this function because it is not I don't need it for anything and it generates a sound that I can't stand. For me, MTW3 have a beautiful, spacious, dynamic and clean sound. I had dozens of headphones from different companies, wired, wireless, large and small. None of them sounded like these. Finally, after dozens of years, I found what I was really looking for. I also had MTW 2's but they don't sound as good as these, although they are really good. The only problem I had with them was that the mesh securing the channel to the inside of the handset got dirty. But this is normal because there is moisture inside the ears. It wasn't wax because I care about my ears being clean, maybe even too much. The next problem is that the contacts on the headphones get dirty, but this is not a major problem for me. All you need to do is wash them with alcohol from time to time, the only thing that should be changed to be fully aware that this is happening is to add charging controls to each earphone. It's not like it is now where there is one control for everything and you don't really know whether both headphones are charging or just one. There is also only one in Technics, but when there is no good contact on the contacts, the light flashes quickly. All Technics models are out of the game because they do not sound as good and natural as MTW3. An additional problem I have with two pairs from the beginning of production is that the headphones automatically discharge the charging case. Because they don't go to sleep or there is some other problem in the electronics. After disconnecting the battery from the handset, the battery itself does not lose charge.The remaining 7 pairs I have do not have this problem, they can be left unused for months. In the case of defective ones, I must remember not to leave them without charging for several months, even though they will be charged to 100% together with the charging case. If I forget about them, I will have to play a game of disassembling them and raise the voltage above 3v. Because when the voltage drops below 3v, the charging case does not recognize the headphones even though the indicator shows that the charging process is in progress. Yes, it only lasts forever and without results. After increasing the voltage to 3v, everything returns to normal and the headphones work again as before. This is definitely a problem, but it is not as important for me because I use them very often. And the sound quality compensates for all these imperfections.
