• IMPRESSIVE SOUND QUALITY IS THE ULTIMATE GOAL: The High-fidelity stereo sound benefits from the 40mm neodymium driver, CSR , and the around-ear cushion design which provide a well-closed and immersed environment for your ears, Just lose yourself in the music! NOTE: B39 headphones 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. 2. The closed-back design provides immersive Hi-Fi sound with CSR chip and 40mm driver together, it is better than ANC in term of sounds quality.
• BUILT TO STAY COMFORTABLE: The Memory-protein ear cushion simulate human skin texture, ensuring lasting comfort. The stainless steel slider and softly padded headband allows you to find the perfect fit without constraint and provide excellent durability.
• NEVER POWER OFF, BOTH WIRELESS & WIRED: 1. The wireless mode: Battery update to 6+hr music time/ talking time in a single charge. A 10-minute charge gives 2 hours of play when battery is low. 2.
