I am completely satisfied. The sound quality is great. I hear with the headphones Bowers & Wilkins P7. It is very good that automatically connects to devices when they were coupled and close when you turn on the Sound Blaster E5. 2 devices can be connected simultaneously, although only one of them always transmits sound to the headset. The weight is just so, the impression could be a bit better. The build quality is not quite perfect (for me, the rear panel jacks is built not very clean, it bulges slightly outward by, but does not interfere). The app on iOS and Mac are hakelig. You are looking for a very long time for the device when it is connected via Bluetooth. The app is dispensable. I would the device to others.
