- A very decent sound. Good low. There are no extraneous noises. Good sound insulation The battery holds a charge for a long time. To defuse - you have to try. Lightweight, with long wear (3-4 hours), the head does not get tired, the ears do not press and do not sweat Connect to everything you can My battery is almost done? It doesn't matter . they work on the wire even when they are discharged. The sound isn't any worse. Auto-off when the BT connection with the sound source is disconnected.
- There is no charge indicator when connected via BT to the phone. Not to say that a big problem, given the time of work, but it is. From the moment of "beeping" about a low charge to shutdown no more than 20 minutes. For a year I discharged to such a state only a couple of times. Flimsy assembly, after half a year, when walking, something began to creak in the ears There is a microphone, but it is not. The interlocutor does not hear me practically. As a headset to the phone can not be used. When connecting BT, they look for the last device used and connect to it. It is inconvenient if there are several sources in parallel. You must first turn off the BT on all other devices so that the ears themselves find the "right" device. Perhaps someone will say that the design is not very, I would say an amateur. A year later, the ear stopped working.
