Sony’s MDR-AS600BT Bluetooth earphones

San Diego — Sony Electronics took the wraps off four Bluetooth headphones, including a model with a whopping 30-hour battery life.

The top-of-the-line over-ear MDR-ZX770BN feature 40mm drivers, active noise canceling, AptX support and a battery life listed at 13 hours. A cable is included for wired use should the battery die. 

They will be available next month in black or blue for a $229 suggested retail.

The step-down MDR-ZX770BT ($149) also features 40mm drivers and AptX support, but it cannot be used as a wired model when the battery dies. The battery life instead gets a bump to 17 hours. They will also be offered in black or blue.

The MDR-ZX330BT brings the battery life even higher, to 30 hours, but drops the AptX support. These on-ear headphones have 30mm drivers. Suggested retail is $99.99.

Finally, the MDR-AS600BT earphones are geared toward athletic users. Features include 9mm drivers; IPX4-rated water resistance; one-button control for play, pause, volume and track selection; and an 8.5-hour battery life. They will come in black and orange for $99.99.

All of the headphones feature NFC technology for one-touch pairing, and all charge via MicroUSB. They will not replace any older models, but instead will supplement Sony’s current offerings, the company told TWICE during a preview last month.
