With P7, we have created a headphone driver that works more like the drive unit in a hi-fi speaker, with a diaphragm focused purely on the job it's supposed to do: generate sound. Which means a drive unit with a more precise, controlled movement. Connectivity Technology: Wired P7's ear pads feature a dual cavity cushion design that helps the pads mold to the contours of the wearer's head. This design maintains a consistent volume of air between the drive unit and the surface of the ear at both sides of the head. Not only is stereo imaging enhanced, but the sound is optimized for every listener. Frequency range-10Hz to 20kHz

HEADPHONES ON, NOISE OFF: Significant ANC technology effectively quells airplane cabin noise, city traffic or hubbub in a busy office, helps you focus on what you want to hear, enjoy your music, movies and videos. The noise cancellation function can work well both in wire and wireless mode. NATURAL HD SOUND: High precision-engineered 40mm stereo drivers combined with advanced Bluetooth CSR chipset deliver powerful and steady audio. Otium Active Noise Cancelling around-ear headphones give a powerful and crisp sound, making your overall listening experience much better. OVAL EARMUFFS ERGONOMIC DESIGN: 90° swiveling ear cups & extendable arm & adjustable foldable headband not only designed for saving your desk space but for helping the headphones fit snugly to your head, professional Protein Earpads lengthen the wearing time with comfort. An ideal music companion for traveling.
