Phaz is hoping to grab some of your dollar's music-listening attention with its newly launched P2 headphones. This over-the-ear headset is powered -- while in active mode -- by a 1,200mAh battery that'll also charge your phone via a USB port while you're listening. The controls are dead simple: On the bottom of one earpiece is a button that fires up the headset's amplifier to ramp up the sound output and on the other is a button for 15dB of bass boost, though neither are necessary to listen to music. These cans are surprisingly light and come wrapped in carbon fiber from the housing to the head strap, and while that look is often reserved for the automotive world, it works well here. The perforated leather-material cups are soft, comfy and come in orange, purple, green or black. We only had a quick demo at the show and while the Phaz P2s did sound fine, the ridiculous level of the background sound means we'll need another listen to really judge them. The headset is available for $249 on pre-order now and should start shipping in April.
