I received this headet as a reward after filling in some surveys. The wireless sound via this SHB9000 series headset is really clear, which is amazing because I thought bluetooth would't be capable of transmitting in this quality. The betterylife lasts way more than 18 hours. I charged this headset for a few hours (no idea if the battery was full yet) but it still runs on this single charge, using it for skype and music every day. Simple design, but since I'm not that type of guy who uses these things outdoors anyway. Would recommend it to anyone.
