Pros:
The sound is pretty good, some artefacts here and there.
mic seems to work well when it connects properly. (maybe dongle related)
That's kinda it really.
Cons:
No Bluetooth dongle
connection issues (Bluetooth dongle related)
Wootwares return policy. (they will charge you 25% of the cost if you opened the box)
Headphone covers are a little small and don't cover the ear.
The power on voice
