Deliver flexible audio for work, travel, and everyday listening with the Supersonic BL Headphone Slv. Bluetooth 5.1 provides wireless connectivity to compatible devices, while the 10 m connection range supports comfortable movement without staying tethered to a desk or pocket. A 40 mm speaker helps produce full-range sound for music, radio, and voice calls. The built-in lithium rechargeable battery supports approximately 6 hours of play time, with roughly 2 hours required for charging, making it easy to keep the headset ready between uses. For situations where wireless is not ideal, the AUX input adds a wired fallback for broader device compatibility. FM radio support expands how the headset can be used beyond streaming, and the hands-free microphone makes call handling more convenient. With a 3.5 mm AUX-compatible design and a straightforward feature set, this model fits users who want a simple, portable headset that covers the essentials without unnecessary complexity.
