- Sound quality, battery charging speed, design, comfortable ear pads, comfortable fit in the ears, microphone quality, ease of pairing, brand.
- A cord stub is included, displaying the remaining charge (maybe this is a problem on the side of the phone, but most of the time it shows 100% charge, then sharply 20% and die after 10 minutes). When running, they bounce and fall down, you need to hide under clothes. Moreover, they run away from under the T-shirt, you need to show off in order to fix them there. Sometimes they don't match the first time, but it's not critical. Apparently you need to first turn on bluetooth on the phone, and then headphones. Unfortunate location of the LED indicator - with a long press on the power button, it is not visible under the finger. I supplement the review: after 8 months, the left earpiece died.
