Ideal for listening to music, watching videos, movies, listening to the radio, web conference calls, and making phone calls. [Comfortable and Portable] Made with thickened silicone and plastic for superior durability, the B-01S dual-use headphones (wired and wireless) combine ergonomic design with adjustable elasticity to fit the ear cups perfectly. Weighing just 0.25g, they're made with soft, comfortable, premium PU protein leather for the same comfort as wearing headphones without them. Even with all-day wear, there's virtually no discomfort, such as pressure or stickiness. Thanks to 5cm of left and right adjustment and an ergonomic design, both children and adults can find the perfect fit. The foldable design not only saves space but also makes them easy to carry. Suitable for commuting, school, and outdoor activities. [Wireless & Wired] The built-in 1000mAh battery provides 46 hours of music playback on a single full charge.
