FiiO Q3 DAC and Headphone Amplifier HX AAA AK4462 XMOS XUF208 32bit 768kHz DSD512

FiiO Q3 is the new portable high-quality balanced headphone amplifier with DAC combo, that is in the middle between the highly appreciated and popular Q1 Mark II and the Q5S Type C

Based on an updated and especially optimized circuit design employing top-end audio components, offer a superior sound quality and a power output of the amp section that double the one of the Q1 Mark II.

Specifically designed for the iPhone

By connecting the included Lightning-tomicro USB cable from the iPhone to the Q3, you can continue to use your 3.5mm headphone jack headphones for the highest-quality audio. Your iPhone has never sounded so good.

Android compatibility: Q3 is a standard DAC & Amplifier that supports USB input, following the USB audio transmission specification. Theoretically,it supports any players with USB audio output, which means as long as your Android phone supports OTG audio output, it can be used with Q3. But the USB output of some Android phones are not so standard, so whether Q3 can work normally for your Android phones, it depends on the Android phone, instead of Q3. If you have this kind of concern, please consider carefully before purchasing. Thank youfor your kind understanding.

THX AAA-28 Amplifier

The Q3's amplifier stage uses a THX AAA-28 chip that incorporates specific technology to achieve a very low level of distortion for high output, while maintaining a neutral and pure sound.

AK4462 DAC

The digital/analog conversion stage is entrusted to an AKM AK4462 DAC chip, which incorporates the proprietary Velvet Sound technology. This chip supports high sample rates up to PCM 32 bit 768 kHz and up to native DSD512. So you can enjoy your high resolution files and the smallest details of your favorite songs.

USB XMOS Interface

An XMOS XUF208 chip ensures that the Q3 receives high-quality USB audio signals, while also enabling support for high-resolution files, so you can take full advantage of the Q3's DAC performance.


In continuity with the other models already offered by FiiO, the Q3 takes up the design, sober and elegant thanks to the soft curves. The housing is made of aluminum and is particularly robust.

Connectors and LED indicator

The Q3 features full connectivity, with an unbalanced 3.5mm jack and a balanced 2.5mm/4.4mm jack output.It will then allow you to connect all kinds of headphones to it.

The volume knob's RGB LED indicator changes color, allowing you to quickly identify the sample rate of the file being played.

  • ≤ 48kHz : Blue
  • 48kHz : Yellow
  • DSD : Green


The Q3 adapts to all situations and all types of listening. A switch allows for example to activate or not the Bass Boost function. For this functionality, a hardware circuit increases the gain by 6dB in the low frequencies, without affecting the mids and Plus, for more convenient use, a multifunction knob lets you quickly select a gain level or filter.

Volume control

Using an analog volume control, the Q3 ensures precise adjustment of the volume level. An ADC reconstruction curve also allows you to overcome the typical problems of analog controls.

Substantial autonomy

Leveraging an 1800mAh battery, the FiiO Q3 offers a significant battery life of at least 10 hours or more in USB decoding mode.


The Q3 with its aluminum housing and copper-nickel shielding effectively rejects RFI interference that could affect signal quality.

You can connect the FiiO Q3 to your iPhone/iPad/iPod by purchasing the FiiO LT-LT1 separately (click here).

    Dovrei pilotare una Sennheiser 599 attraverso un iPhone con il nuovo standard (per apple) hi res. Che vantaggi avrei rispetto ad uno q1 mkii?
    • PlayStereo
      2021-06-11 10:32
      Buongiorno Sergio, il Q3 è un modello superiore rispetto al Q1 mkII e questo si traduce in una maggiore qualità della conversione digitale-analogica, e anche in una maggiore qualità e potenza dello stadio di amplificazione interessa per cuffie.
