What it brings to you is clear quality sound using jAuraTM acoustic speaker technology playing music from your iPod, CDs, MP3 CDs, USB or AM/FM radio. What you bring is music from an audio device, computer, mobile phone, etc. designed with Bluetooth wireless technology and, thanks to the BluePinTM wireless audio transmitter/receiver, that too can be played through the system. In return, you can listen to music in your room wirelessly on headphones or speakers equipped with Bluetooth wireless technology. It's give-and-take. Your music can put you to sleep or wake you up and you can always know the song title and artist on an MP3 track if it has an ID3 tag. With the AV output, you can even send video content from your iPod to a TV. This system gives you a lot, and you can give a little something in return.
