1.8 mm diaphragm fullrange driver delivers clear audio with resolution, preserving details without distortion for an immersive listening experience. Fingerprint touch design enables simple, precise control for switching between functions without difficulty. Dualsource connectivity: the two earbuds can be independently connected to different audio signals without interference, and they can also be connected to the same signal at the same time for a true stereo experience. Upgraded Bluetooth 5.2 chip reduces power consumption and latency, extends battery life, and provides improved overall efficiency. Use scenarios Daily listening on the go: enjoy music, podcasts, or videos with stable wireless performance and clear sound while commuting or multitasking. Watching videos or gaming: low latency from the Bluetooth 5.2 connection helps keep audio synchronized with onscreen action. Flexible device use: when you have two devices, each earbud can connect to a different source independently, or they can be used together with the same source for seamless stereo playback.
