We have an awesome new accessory for Android devices to tell you about today. A company called Spar has just announced three new Bluetooth speakers in a new line called Zephyr. They'll be offering the Zephyr 550 (biggest of the bunch) with 30 hours of playback, the Zephyr 500 with 18 hours of playback, and the 300 offering 12 hours and all of this from a single charge. What makes these special you ask? The Zephyr will also charge your device via USB port when needed or while you're on the go.
