Audio performance

Driver unit: equipped with 11mm+6mm ultra-clear integrated coaxial dual units, with an 11mm dynamic unit responsible for low frequency and a 6mm dynamic unit responsible for high frequency. The dual units are coaxially arranged, and each sound unit is independently driven by a decoding chip, which can present clearer sound details, rich bass and transparent high pitch.

Audio technology: supports BassWave 2.0 dynamic low-frequency technology. When the music has less low frequency, it can automatically compensate for the low frequency to make the sound fuller; it has a "golden hearing" function, which can detect the user's ear canal structure, optimize the audio algorithm and compensate for hearing loss to restore the best listening state.

Audio decoding: Supports LHDC 5.0 transmission protocol, supports up to 192KHz, 24bit LHDC V5 lossless transmission mode, and cooperates with dual DAC decoding driver to achieve high-resolution audio playback, bringing users a high-quality music experience.
