1. Ergonomics. Judging by the reviews, among other headphones of this type in this price segment, these sit better in the ears. So I confirm, I bought two pairs in turn - perfect. Nobody complains that they fall out, they sit like a glove.
2. Next . sound. It would be wrong to expect studio sound from earbuds. But even so, we get a pleasant listening to music. In general, the balance of frequencies "out of the box" suited me. It is very pleasant to listen to music in them.
3. Microphone . As many people say, the microphone is their strong point - high-quality, does not cause inconvenience. When talking, everyone hears everyone everywhere as it should.
4. Connect . Two pairs were tested on three phones: an old asus, xiomi and iPhone 11. The work is stable everywhere, unexpected disconnects and sound interruptions were not noted. However, I tried in 3k square. brick at home, if the phone and headphones are moved as far as possible, then the connection begins to be interrupted. I think this is plus or minus the norm for all bluetooth headphones.
6. Charge. Hold equally well and headphones and boxes. Many wrote that it often happens over time that the volume on one earphone stops working or stops charging or, on the contrary, starts to discharge, etc. Mileage three months of active use. Nothing of the sort has come up yet. There is wireless charging, but I haven't tested it.
