Quality
The headphones sound great, and the build quality is top notch. They're comfortable to wear for extended periods, even for my large head.
The Bluetooth connection is strong. It takes several walls between them and the source, to disrupt the connection.
I primarily use them with my TV, playing Netflix and xbox. I haven't noticed any lag between the audio and video.
I've only been using them for a couple of days, but so far, the battery life is excellent.
My only complaints are - that during calls, I can hear myself and ambient noises through the speakers. The calls are fine it's just a minor annoyance.
- And the lack of active noise cancelling is disappointing. Other head phones in this price range (and cheaper) have ANC. It's a strange omission. It's not a deal breaker for me, but maybe for some.
