Query: Works great under 20 feet away......

This bluetooth adapter is being used to stream both xm satellite radio and a police scanner to a Motorola H605 headset. This adapter works well for distances under 20 feet. Over that distance, there is some static, but still acceptable. I am not using this adapter to communicate from my cellphone. For my hobby interests it is terrific though. So, if you want to connect to a radio or mp3 player, get a 3.5mm adapter and you are set to go. I recommend this adapter for its intended purpose and for other hobbies as well. I'm getting a solid 8 hours of 'continuous' audio on a single charge.
