Sony LinkBuds S Wireless Stereo Lightweight Compact Noise Cancelling Ambient Sound Mode Versatile Usability Black BC WF-LS900N Noise-Canceling

• Ultra-compact and lightweight design: The body size has been reduced by 40% compared to the WFM4, resulting in a comfortable fit that is less tiring even when worn continuously, and improved wearing stability. • High noise cancellation performance: Equipped with the same integrated V1 processor as the WF-1000M4, achieving high noise cancellation performance despite its small size and light weight. • High ambient sound passthrough performance: Significantly increased ambient sound passthrough compared to previous models, allowing for listening while doing other things without removing the earphones. • High-quality call performance: High-precision voice pickup technology delivers superior call quality compared to previous models. • User-friendly and personalized: Features include automatic control, high performance, IPX4 water resistance, and 3D audio support, along with various other user-friendly features. In addition to being the world's smallest and lightest (*) design with noise cancellation and Hi-Res audio support, the design minimizes the amount the earbuds protrude from the ear, bringing the center of gravity closer to the head and ensuring a stable fit. Furthermore, it employs an "ergonomic surface design" that increases the contact surface between the earbud body and the ear. The shape is less likely to interfere with the complex contours of the ear, allowing for comfortable use even during extended periods.
