FiiO M17 Music Player MP3/MP4 Portable Desktop Hi-Res Android 10 THX AAA-788+ MQA 8X 3.5mm/6.3mm/2.5mm/4.4mm Bluetooth 5.0 aptX Adaptive Standby 1000h

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. 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 DAPs features : 3.5mm output: headphone out/line out; 6.3mm output: headphone out; 2.5mm output: balanced headphone 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, can be used for high-speed data transfers and fast charging; USB 2.0 port: supports USB Host mode, 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 DAPs. Not only are “H” type heat dissipation and VC liquid cooling technologies adopted, the 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 portable 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 in situations where there is no access to a power outlet. Under DC power supply, voltage in the analog circuit is increased by 35% up to 11.5V compared to under 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 balanced output, gain can get as high as 16dB – allowing the M17 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 : Massive 9200mAh battery allows for a battery life of up to 10 hours on the M17 music player. It can be charged either through USB or through DC in from an external DC adapter. 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 M17 features a seven-color RGB ambient light system with extensive customization options. Colors can be set to be either fixed, to follow the audio, or to follow a cycle. 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.
Connection methods: With speakers: DC+LO+speakers; With computer: USB DAC+headphones; With desktop DAC: USB/coaxial output+DAC; With hard drive storage: DC+USB2.0+hard drive+headphones; With Bluetooth headphones: Bluetooth transmitter+Bluetooth headphones; Coaxial decoding.
