JBL makes some truly great portable Bluetooth speakers, as well as some nicely priced multimedia speakers. That’s why we have high expectations for the Pebbles Stereo Computer Speaker System ($59). Visually consistent with the company’s recent iOS audio systems, this new pair of speakers will sit on your desk and make a great addition to an iMac. JBL has packed them with 50mm drivers, as well as built-in cable management to reduce clutter.

Pebbles connects to your computer via USB. This means the audio signal is totally digital, and there’s no need for a separate power source. Both speakers feature a brushed metal plate on the front, with one serving as a rotating volume control; it keeps in sync with your computer. If you do decide to take Pebbles on the road, there’s an aux port for alternative audio sources.
