Bought these xtrapris, famous brand.
Says on their website 5tim + battery life.
Ok good bt 4.0 is yes for me, very good contact.
Sound! Yes ..... according to me,
Do not know how well to express myself without the o sound like a know,
Mao.skit in my ears, battering, tiden.klockade them 2 times.
Did not even 4 hr.
Went back to the store pretty fast
Have only had them for a little while (possibly come back and update later), but I'm satisfied. Starting to get the technology to get them into the ear, and realize that they are very good.
The sound is good, better frequency response than in the past (a little cheaper) Bluetooth in-ears I had. Isolates external sound very good - almost too good.
Okay, I took the chance to buy domhär when all was 799 on NetOnNet,
only used them for a while but pleased, I read that could be a bit lousy with bass, but it's a little myth, the copy I received is the base super good, and the voices are very clear, (listen much to Rapp and other songs with high base)
think they sit very well as regards to the in-ear habit because it is forced to rotate them by pressing the judgment for the blade to fold correctly in your ear,
and they isolate a perfectly good in the outside world all sounds
