• 13mm Bass-Enhanced Dynamic Driver Composite Bio-Diaphragm - Block uses a bass-enhanced 13mm dynamic driver.High efficiency N52 magnet and CCAW coil.Composite biological diaphragm material dome + flexible suspension. Offers smooth high frequencies and punchy bass. 
• Tuned with B&K5128 Offers Punchy Bass without Sponge Eartips - In contrast to previous ear simulation devices, the new wideband B&K5128 HATS has a more realistic auricle and ear canal structure and uses finer materials to better simulate the acoustic characteristics of real-life listening. 
• VDSF Natural Timbre Tuning - The VDSF Target Response is based on the coupling changes produced by sound propagation within the human ear (HRTF) and can be regarded as a template for restoring the most natural timbre possible. 
• Dual-Microphone Beamforming ENC - Using the principle of beamforming, Block's environmental noise cancellation (ENC) greatly reduces environmental noise during voice calls and minimises the impact on incoming calls. 
• Touch Operation Seamless Monaural-Binaural Switching - Block supports touch operation play/pause, mode switching, and other functions.It supports TWS mirroring, enabling seamless switching between monaural and binaural modes, and adaptation to various usage scenarios.
