MDR-XB650BT headphones combine powerful EXTRA BASS sound quality with the freedom of wireless connectivity and long-listen comfort. Tailor-made for dance music, innovative Extra Bass technology delivers deep, punchy bass. Part of the Extra Bass product range, these headphones incorporate Bass Booster technology. This provides an acoustically-tight seal for superior sound isolation and tight bass response. A longer battery life gives you extended listening with 30 hours of superior sound. And you can enjoy the freedom of wireless connectivity with Bluetooth and NFC one-touch listening. Compact and lightweight, the MDR-XB650BT headphones' design not only delivers long-listen comfort but also helps optimise bass. The adjustable headband's structure is optimised for deep bass playback, providing a stable fit to minimise vibration caused by punchy bass notes. Soft cushion ear pads provide a largely airtight seal for direct bass transmission. When not in use the ear cups swivel flat for easy packing.
