I've had these for a while now. 6 hours battery life when listening to music is pushing it. I would be confident that they would reach 3 hours.
The description makes it sound like they have active noise cancelling, they do not. They passively block out outside noise pretty well. This is helped also with them being able to go loud. The sound is punchy.
They are pretty good for work out sessions or commute to work, they are light and stay in my ears well even without the extra fins which I removed. I'm not critically listening when I'm trying to navigate people at the train station, I just want my music to drown them out, and these do that.
The battery case feels a bit cheap.
The controller buttons are pretty good, 2 on each side, giving you a dedicated button for volume up / down and next / previous track, pretty convenient.
The ear pieces themselves seem well made.
I get some Bluetooth drop outs walking around in the CBD.
Also when watching YouTube, they do lag.
Finally, the customer service seems pretty good. All the rep names seem to be Russian or from the neighbouring countries.
