LAS VEGAS - A new model of headphones can play MP3s themselves, without connecting to a separate device.

Hauppauge, N.Y.-based Adrenaline Technologies LLC is releasing SlotPhones, a pair of wraparound Bluetooth headphones that work as a standalone MP3 player if you insert a song-filled microSD memory card into a tiny slot on the side. The product also serves as a stereo Bluetooth headset that can receive calls and music from your cell phone.

Adrenaline Technologies showed the lightweight, collapsible gadget this week at the International Consumer Electronics Show, and expects it to be available in the second quarter for about $130.

The SlotPhones name echoes that of the recently released slotMusic format supported by SanDisk Corp., four major record labels and retailers Best Buy Co. and Wal-Mart Stores Inc. SlotMusic comes on 1-gigabyte microSD cards loaded with music free of copy protections. Some full-length albums are being sold in this format — and now they can be played on SlotPhones.
