I added the Spracht Aura Mobile to my BMW Z3 Convertible, a very loud ride when the top is down. I was amazed at the sound quality for me and for my wife that I speaking with. Even at highway speeds, an unusally harsh situation, this product preformed.I also like the ability to take this with me on business trips and host high quality conference calls from my hotel room, that is sharp.I would recommend this product to people that want to use their mobile phone hands-free, which should be everyone.
