Thrill to every nuance while listening to recorded music being delivered to your ears alone, without encumbering on anyone else. This cordless headphone uses 2.4GHz wireless radio frequencies allowing you to move up to about 90 feet from the source. This means you can enjoy the comforts of your home and even the patio while listening to the MFR-S6000 headphones. In addition, it's geared to deliver virtual surround from 5.1 channel sound sources. That means these headphones are a suitable match for home-theater sound. Sit back, relax, enjoy what you're listening!
