Armed with a long-lasting battery, these headphones will keep going wirelessly for up to 22 hours, even with the Extra Bass and Noise Cancelling turned on. And when they do finally run out of juice, simply recharge via USB, or plug in in traditional fashion with the included audio cable. Extreme Comfort Sporting a metal headband with a soft cushion and around-the-ear pads for a snug, comfortable fit, the XB950N1 can be worn for hours on end. The light but durable material gives a premium look and feel, while suppressing deep vibrations and punchy beats. The ultra-thick earpads seal in the sound by perfectly fitting around your ears. Not only is this pressure relieving but the earpads also keep the music in and naturally lower external noise too. Better still, you can take your music anywhere. The sliding metal headband and swivel folding earcups make it easy to store your headphones in a suitcase or bag.
