Edifier has released TWS headphones W240TN . The model is interesting due to its double coaxial design of speaker coils.
The W240TN dual moving coil coaxial unit consists of a 10mm full-frequency active coil and a 6mm high-frequency auxiliary coil on the same axis, which improves the amplitude synchronization of the two diaphragms and suppresses audio distortion. The W240TN features Hybrid Active Noise Canceling ANC with noise reduction up to 38dB.
The W240TN also features a low latency mode that reduces gaming and video playback latency to 80ms. Supports Bluetooth 5.3 standard, A2DP/AVRCP/HFP profiles are supported. The codec only supports SBC. The headset provides up to 25.5 hours of playback, and a 10-minute quick charge provides 2 hours of playback.
