have bought the headset for two main reasons: 1. I want to see who is calling without the cell phone out of his pocket or having to dig its holster. 2. Better understanding in noisy environments with two earphones. Both requirements are met the SBH50 in full. I previously had a Plantronics headset in which you wear all the technology directly to an ear and there the problem that I have hardly understood in a noisy environment what. Partial bit awkward, I find the use of the SBH, Redial eg not achieved as to expect simply by pressing the call handling key but by holding down selbiger, followed by 2x Play / Pause. If you have previously listened to the radio or music you have even 2x press the "Back" button to only to get time on the home screen - ie 5 key operations for easy redialing. If you opt for this headset you should also think about whether you previously on the Clothing the way it has to be attached to the clip. For T-shirt carrier is not much, either above the collar with the disadvantage that one the display can not see, or at the end of a sleeve (by me preferred) with the disadvantage that one the Must thread the cable through the clothes but that the display has an eye) Of course, the shirt wearer has more opportunities there. Bad solved I think the acoustic feedback in actions. Neither on nor when closing a connection, there is a confirmation tone and when you turn the device can hear beep only. My old Plantronics there was much more talkative: "Power on, Phone 1 detected, Talk Time 10 hours" drowned it out of the receiver when I turned it on and for every action, there was an acknowledgment tone. Despite everything, however, outweigh the benefits for me of SBH 50 compared to a simple "Button in Ear" and the operation can get used to. Music and Radio function are in the superior sound quality, radio reception is OK. At runtime, I can say that at about 2h. Talk time and 1 hour. Radio / listening to music after a day three days still 50% on the battery are. The Bluetooth range is also good - I reach about 10 feet at sight or 1 room with wall in between.
