Know before you buy
The dual ports separate data and power functions. One port handles USB 3.0 data and standard charging, while the dedicated power port allows you to bypass the battery for Desktop Mode, which helps preserve long-term battery health.
Yes, the M23 runs on an open Android 10 operating system. This allows you to install your preferred third-party music streaming apps directly onto the player.
Desktop Mode is designed for stationary listening. When activated via the dedicated power port, it bypasses the internal battery to prevent degradation, while also enabling the Super High Gain Mode for increased output power.
With its THX AAA 78+ amplification and a balanced output of 1000mW+1000mW, the M23 is engineered to drive most high-impedance headphones with ease, especially when using the Super High Gain Mode.
The primary difference is the build material and weight. The stainless steel version is significantly heavier at approximately 392.3g compared to the 299g aluminum alloy model, offering a more substantial, premium feel in the hand.
While 64GB is standard, the M23 supports external storage expansion via a microSD card slot. This allows you to store large high-resolution music libraries without relying solely on the internal memory.
