- The sound is excellent, they sit on the neck and in the ear comfortably. As a headset, they work perfectly even with a strong wind, the interlocutor will hear you. Hold a charge for a long time.
- There is no volume control. A very alternative touch control, if you want to fix the earpiece in your ear, you have to block the control, otherwise it works like a press. Sometimes the sound is interrupted for half a second, but I'm not sure that it's not the smartphone.
