The FiiO M9 is the latest portable high-res DAP/DAC from FiiO. The M9 uses Bluetooth 4.2 and supports virtually all Bluetooth formats including the high-resolution ones for your ultimate listening pleasure, including: 24-bit aptX HD (also backwards compatible with aptX), LDAC, and HWA.

The two AK4490EN DACs employed in the M9 feature a high signal-to-noise ratio, exceptional dynamic range, and low distortion – making for a precise yet exciting sound signature.
Inside the M9 is a high-performance A3P030 FPGA, responsible for ensuring your music (whatever sample rate) is played back accurately by stabilizing digital clock signals. The FPGA also decodes DSD64/128 in hardware, which the M9 supports in ISO/DFF/DSF formats.

Under normal usage the M9 can last around 10 hours, while in deep sleep (standby) mode the M9 can be still be used after a whopping 45 days! And being in deep sleep mode does not mean sacrificing convenience – just hit the power button, and the M9 instantly is ready to go. The M9 contains both single-ended 3.5mm and balanced 2.5mm audio jacks, for even more ways to listen with your headphones. The M9 also supports in-line controls in both CTIA (common with Android headsets) and iOS headsets. (With iOS headsets, only play/pause functionality is supported.)
