I am very pleased to have these headphones perform to my expectations. I was skeptical, being a music enthusiast, about A2DP compression and frequency response, but that proved to not be a issue for me. True audiophiles will still require wires though--there is a compress/decompress delay of approx. 180-190 milliseconds on my machine (Windows 7, lean). Linux is even less; not even noticable. This is just a warning to those who might do audio/video editing. Advanced media players can timeshift audio, no worries.

Windows 7 does not provide A2DP drivers. The most common driver you will have to Google is by Widcomm/Broadcomm--something like that. Read through forums to figure it out. Linux Mint picked up on it out of the box. Windows is still temperamental with it, but ... Windows is temperamental and I'm a super user.

Will help to be IT savvy for any Bluetooth audio products at this stage. I gave full 'ease of use' rating because it's not the headphones causing complications.

Charge time is quick--maybe 40 mins. Last me several days @ several hours constant use per day. No complaints here.
