IMPRESSIVE SOUND QUALITY IS THE ULTIMATE GOAL: The High-fidelity stereo sound benefits from the 40mm neodymium driver, CSR chip, and the around-ear cushion design which provide a well-closed and immersed environment for your ears, Just lose yourself in the music! NOTE: Mpow 059 headphones are passive noise isolating, NOT active noise cancellation(ANC), they can't cancel the noise completely but they won't drain the battery and damage the sound. 2. The closed-back design provides immersive Hi-Fi sound with CSR chip and 40mm, driver, together, it is better than ANC in terms of sound quality.

BLUETOOTH 5.0 & BUILT TO STAY COMFORTABLE: The Memory-protein ear cushion simulates human skin texture, ensuring lasting comfort. The stainless steel slider and softly padded headband allow you to find the perfect fit without constraint and provide excellent durability.

65 HOURS NEVER POWER OFF, BOTH WIRELESS & WIRED: 1. The wireless mode: Battery update to 65-hr music time/ talking time in a single charge.
