We've been seeing Bluetooth speaker after Bluetooth speaker debut as of late, but Felt Audio's $99 rechargeable Pulse is one of the smallest of its kind. It supports Bluetooth for up to 40 feet, and it pairs with enabled devices in about three seconds. Battery life is rated for about four hours, and the speaker recharges via micro-USB. The controls are intuitive: you can manage calls and change the device's volume via buttons on the side. A clip on the back can be used as a stand for propping the device up during conf calls and the like.

Felt also showed off its larger Rewind speaker (also for $99), which adds more functionality in the form of built-in earbuds that retract up to three feet. When we cranked up some tunes on an iPhone, the 9.2mm drivers cranked out enough noise to be heard over the raucous CES showroom floor. Both the Pulse and Rewind can attach to optional cases -- currently only available for the iPhone, iPod and iPad. Both speakers will be available in April, though pre-orders begin in March. Get a closer look in our hands-on gallery.
