IMPRESSIVE SOUND QUALITY IS THE ULTIMATE GOAL: 1. 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. As an additional factor of sound quality, it is better than ANC. 2. The closed-back design provides immersive Hi-Fi sound with CSR chip and 40mm driver together. If you care more about Noise Cancellation than Sound Quality, you may consider other alternatives.
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 20-hr music time/ talking time in a single charge, instead of 13-15 hrs from Oct 1, 2017; 2. The Wired mode: you can also use it as a wired headphone with the provided audio cable so the headphones will never power off.
FOLDABLE DESIGN WITH A PORTABLE BAG & GENTLE REMINDER : The foldable Headband is not only designed for saving your desk space but for carrying in the provided bag. Gentle Reminder: Depending on your head/ear size/shape, it may be a little tight(feels like“on ear”) for someone to wear which is designed to avoid sound leakage. In case of that and to get both audio and wearing comfort, please take off the headphone every 1-2 hrs to get your ears relax and protect them from muggy environment in use.
