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

NATURAL AND CRISP SOUND: Finely tuned 40mm driver units and CSR chip give your music the rich sound it deserves. Mpow H7 offers you bettter overall listening experience.( PLEASE NOTE: This item is passive noise isolating, NOT active noise cancellation(ANC), it can't cancel the noise completely but it won't drain the battery and damage the sound.) BUILT TO STAY COMFORTABLE & OVAL EARMUFFS ERGONOMIC DESIGN: Memory-protein ear cushions, adjustable headband and oval earmuffs ergonomic design allow for comfortable all day listening. Getting better hearing enjoyment for travel, work and anywhere in between. IMPORTANT HINT&COMPATIBILITY: Please make sure the driver software of receiving adapter is fully updated when connected to PC or laptop, and you need a SEPARATE BLUETOOTH TRANSMITTER when connected with TV,PS4,Google Pixel 2 XL ect.
