Normally when I get a product to test, I use it for a while, get a feel for the end-user experience, then I rip it apart. Even if it's not intended to be a Tear Down article (of which I write many), I can't help myself. I need to see how it was designed, whose components made the cut, etc.
In this case, the product was a set of Motorola Bluetooth stereo headphones (model HT820). They sent along an adapter to hook up to your stereo (the DC800), but I rigged it to connect to my MP3 player. Boy, was I surprised with the performance. Not so much the audio quality (which was fine), but by the range of the Bluetooth.
I have one of those old houses with concrete walls, so I didn't think it would penetrate well from room to room. Surprise! I went up to the attic; I went down in the basement; I even went outside to the garage. And not once did I lose the signal.
My only disappointment came when I realized I signed one of those forms that forbid me to pop the cover off. I did a little research though, and I believe it's the CSR Bluetooth chip inside, one that I wrote about a few months ago (http://www.wirelessnetdesignline.com/articleID=170101157). I've used a bunch of these headphones, and while I'm not a huge fan of the industrial design, the Bluetooth range is more than adequate. The power consumption is quite good as well.
All in all, this is one of the better consumer products I've experienced.
