sell em at work (halfords)
sold a lot of em in fact.
Pro's: wireless bluetooth hands free. being a sony (build quality satisfaction). completely black wiv distinctive blue back lighting. if you go for the bigger box package, u get this little bluetooth reciever which you can use to plug into your mp3 players and then stream the audio from your mp3 player or ipods wirelessly via bluetooth. also has a Line In 3.5mm jack on the front for a direct wired in approac for portable media. wireless microphone for handsfree is built into the head unit so no need for routing an external microphone
Con's: Some would consider a high poularity of these units being a con as they wud want something different to others. the microphone built into the headunit can be a con also as most other methods use external mic's where it can be located nearer to the drivers speaking position n therefore can b more clear. Does NOT have any pre-outs for any future addition of bass enhancement. i.e. amps n subwoofers.
Other than the points made above, everything else is just cushty....hope that helps
