Dock. Pair. Play. iSkin makes it that easy to enjoy audio from speakers up to 30 feet away from your smartphone. Once plugged into your speaker system’s dock connector, the Cerulean RX waits to be paired with your iPhone or other Bluetooth-capable device — no drivers, downloads, batteries or charging needed. It also automatically re-connects the next time you want to play your audio and doesn’t interfere with incoming calls on your phone, resuming audio playback once your call has ended. Got an iPod, earlier iPhone or other device without Bluetooth? Also available is the Cerulean TX transmitter. Cerulean RX is $89.99 with RX + TX combo for $149.99.
