FiiO M17 MP3 & MP4 Player review

Desktop-league DAC ES9038PRO

The left and right audio channels each contain a desktop-class, 8-channel ES9038PRO flagship DAC. This means that each audio channel has 8 parallel outputs summed together for superior resolution and minimal distortion for extremely pure audio reproduction.

Desktop-class THX 788+ headphone amp

Desktop-class amplification also plays an important role in the M17 audio player. FiiO and THX jointly developed the exclusive THX AAA-788+, an upgraded version of the original op-amp. Compared to the original, output power is increased by 225% up to 3000mW per channel with a lower output impedance – allowing it more effortlessly power all kinds of headphones.

Desktop-level connectivity

  • The M17 mp3 player features a 3.5mm output: headphone out/line out
  • 6.3mm output: headphone out
  • 2.5mm output: balanced headphones out
  • 4.4mm output: balanced headphone out/balanced line out
  • RCA coaxial port: coaxial input and output
  • USB 3.0 port: supports USB Host and Device modes that can be used for high-speed data transfers and fast charging
  • USB 2.0 port: supports USB Host mode, which is allowing external DACs or hard drive storage to be connected.

Desktop-tier heat dissipation

With exceptional audio quality comes with large power consumption, so effective heat dissipation was a large focus when designing the M17 music player. Not only are “H” type heat dissipation and VC liquid cooling technologies adopted, the Bluetooth mp3 player M17’s 151g unibody aluminum alloy frame also effectively transfers heat out of the device. Finally, the cooling fan stand also further makes sure heat is rapidly transported away.

Desktop-quality power supply

The M17 digital music player contains two power supplies – a battery power supply and a power supply powered by external DC power. The battery power supply allows you to use the M17 lossless mp3 player in situations where there is no access to a power outlet. Under a DC power supply, the voltage in the analog circuit is increased by 35% up to 11.5V compared to under a battery power supply; and the battery is kept healthy since it is not used in this mode.

Desktop-grade gain

Under battery power, there are 4 gain levels: low, medium, high, and headphone mode. When under DC mode, the enhanced over-ear headphone mode gain is unlocked, with a truly desktop level of amplification gain. In the balanced output, the gain can get as high as 16dB – allowing the M17 audio player to easily drive most headphones.

A true smartphone-like experience

Android 10 OS open to install 3rd party apps; Bluetooth 5.0 with support for aptX Adaptive, supports up to DSD512 and 32bit/768kHz, supports MQA 8x unfolding for master-level sound.

Immense 9200mAh battery

Battery capacity: 9200mAh; Charging time: 4.5 hours; Charging protocols: QC4.0+PD; Battery life: 10.6 hours (single-ended), 8.6 hours (balanced).

Radiant RGB ambient light

The brightness of the ambient light can be set to change depending on the current power, volume, or temperature. And finally, the top and side ambient lights can even be controlled separately, allowing you to dial in exactly how you want your dazzling lights to be.
