REVIEWS:
1) Worth it...: For the price I haven"t found anything that works like this device. I use it for my phone in my car - though no for speaking, just for audio playback as it doesn"t support handsfree. The audio is amazing quality - just like it"s plugged in - love it. It DOES cut out once in a while for a few seconds here and there - but it"s totally worth the money still.

The reason I gave it four stars is for the slight connectivity cut-out problems and because I have to tell my phone to connect to it each time - since it"s not handsfree it doesn"t automatically pick it up when I turn on bluetooth on my phone (really wish you could fix that).
2) As good as I expected.: I have a Nokia N73 with 2 GB memory, and holds hundreds of mp3 songs. I wanted to able to use my Nokia via bluetooth to play the songs by genres on my home stereo. After research, I decided to go with Motorola DC800. The price is very reasonable $67. It comes with all the necessary audio cable. I just plugged the audio cable into my stereo receiver, and very easy pairing with my Nokia by following the quick start guide. The sound quality is as good as I expected, clear, good range, and very little noise. Some reviewer stated poor sound quality, possibilly due to the reduce quality of mp3 format itselt and not the bluetooth device. Might want to increase the bit rate to 192 instead of standard 128 bit mp3 format.

pros: Very affordable price. very small. easy installation.

cons: Does not pair with regular motorola bluetooth headset HS850. As stated on the manual, it will pair with motorola stereo headset HT820, and possibilly with other motorola stereo headset like MOTOROKR S9.
3) Works for me: While the device looks rather plain, it was easy to set up and has worked as expected. I have had no problems with it.
4) Good for some things: I use this product to play radio and music transmitted from my bluetooth enabled laptop to my stereo system. It is great for this; I can listen to public radio stations that are otherwise too far away to pick up.

But I would like to get another unit to attach to my TV so that I can listen to the TV through my stereo system (without wiring). However, when used as a receiver the DC800 requires that you enter a code (0000) via a keyboard. That is ok if you are transmitting from a computer of phone but not from a TV. I do not understand why they made this necessary; since they don"t explain how to change the code it provides no security benefit - it just reduces functionality.
5) The range is terriffic-sound quality perfect.: Pairing with my headphones was quick & easy.

Works great with my HT820 headphones as well as my KRZR cell phone. I was able to vacuum my house while listening to XM radio through my stereo. The headset did cut out a couple of times, then I figured out that my refrigerator was blocking the signal. Walls between my headset and the adapter didn"t cause any problems. I even went a few yards outdoors with no problem
.
After switching over to answer a cell phone call I was able to pick up the adapter signal again afterward with just the touch of a button.

Another reviewer mentioned the slight delay. I noticed it while watching a newscast on TV. I imagine it will be a little annoying while watching a drama. I haven"t tried that yet.
