The Roland RH-300 are stereo headphones with a circumaural closed-back design. They boast comfortable, adjustable padded earpieces, and 45mm neodymium drivers. As such, they can deliver a frequency response of 10 Hz to 25 kHz. An 11' cable gives you plenty of slack. A 3.5mm mini plug, coupled with a 1/4" adapter, provide compatibility with many pieces of audio equipment, professional-grade and consumer alike. A carrying pouch is included.
