A brand new company called Spar is getting ready to release some juicy wireless speakers out into the wild that not only play your tunes wirelessly over Bluetooth, but also pack a built-in rechargeable battery which acts as a battery backup charger that lets you charge any device via USB. Spar's Zephyr wireless speakers comes in three models that feature speakerphone functionality, battery backup charging features and a 3.5mm audio input. The high-end Zephyr 550 features an aluminum enclosure, two custom drivers for room filling studio quality sound and a 3000mAh rechargeable battery for $159.99. The Zephyr 500 has a soft-touch rubber coated plastic enclosure and also features two custom drivers but with a 1500mAh rechargeable battery for $129.99.
Spar's Zephyr 300 wireless speaker has a pocket-sized design and is more affordable at $99.99, and features a soft-touch rubber coated plastic enclosure with an 800mAh rechargeable battery. All three models are now available to pre-order and will ship in mid-December.
