About the Grandmax SPKR-R1-SB-CH

The Grandmax Tweakers GoRock Wireless Stereo Speaker (Charcoal) is the perfect accessory of today's portable electronic devices. Wirelessly stream audio from nearly any portable device to the speaker with Bluetooth wireless technology. Auto-connect and easy-pairing convenience provides hassle-free connectivity. The built-in rechargeable battery provides hours of uninterrupted music pleasure.

If your device does not have Bluetooth capability, you can still use the Tweakers GoRock wireless speaker through the line-in port, which accepts any standard 3.5 mm cable (sold separately). Simply connect the 3.5 mm audio cable to the line-in port and the other end to the earphone port of the portable device. Have the best of both worlds, using a 3.5 mm cable, or wireless streaming. If you need a 3.5 mm audio cable, you can get it here.
