The palm-sized M5 Ultra-Portable High-Resolution Audio Player from FiiO is packed with processors that are engineered to deliver a high-resolution audio experience when on the go. The Ingenic X1000E processor is geared to provide low power consumption without sacrificing performance. The M5 can provide up to 13.5 hours of playback via Bluetooth. Sound quality is taken care of with the AKM AK4377 DAC, which supports native DSD and decoding of PCM and DSD formats with low noise and distortion.

Additional chips include the AXP192 for multi-channel power management, and the Qualcomm CSR8675 Bluetooth chip, which is made to provide lossless playback over Bluetooth. Speaking of which, the M5 is both a Bluetooth receiver and transmitter. When paired with a smartphone, the M5 gives you the ability to make and receive hands-free Bluetooth calls. Dual built-in microphones with cVc technology helps cancel out ambient noises for a clear conversation.
