This sound system is really intelligent. Picture this, a wirelessly connected speaker that also doubles up as a microphone, directly recording your sound onto a mounted SD card. Forget about media player, this gadget will replace your conventional player permanently and also help you perform your karaoke tracks. The Creative Labs system is not just a speaker, as it serves as an extension for your phone too. Just stream a conversation via Bluetooth for crisp quality, and have it recorded on an SD card automatically. The 5200 mAh will keep you entertained when away from power.
