This headset is indeed very comfortable and it does have great sound on both ends. The only issue I have with it is that the earpiece will move in my ear and cause me to have to adjust it from time to time. It simple swivels a bit too easily. If not for this minor flaw I would give it 5 stars because it excels in everything else.
The price here for "new in retail box" is very hard to beat. All in all it's a great headset and very comfortable.
