The sound is amazing to me

This was one of the best purchases of mine - when i decided to switch from wired headphones / headset to wireless to use with my phone, i have no complaint. The sound is amazing when listening to music, easy use via the touch controls, even the mic leaves no complaints on the other end when in a phone call.

However, i realised that with a laptop (windows) the tiny sound lag is noticeable enough to be disruptive when watching videos, as the bluetooth cannot keep up with the video, the synchronisation fails even if i have all the latest possible drivers installed. That's a pity. I was hoping to be able to switch completely to wireless, but for the computer i still prefer to keep the wired headphones. This lag does not occur when watching videos on the phone, looks like the android synchronisation solutions are just working better.

So, all in all, for music listening, for phone calls, or for watching videos on the phone this in-ear headset is an absolute winner, while the drawback is the audio lagging behind the video on computer.

Headphones are great. Assembly, control, sound I liked. Perhaps they are not very suitable for electronic music lovers, where there is a lot of bass. I listen to instrumentals on them and the sound is great. If there is little bass, then there are equalizer settings.

I bought two pairs for myself and my wife, black and white. The black ones work great, but the white one has no sound. The battery, sensors and bluetooth work, but there is no sound. Sent them back. I hope this is a rare factory defect.
