Feel the music through true high-fidelity sound

The dual AK4493EQ DACs work together with six carefully-implemented op amps to form a truly balanced audio design.4-channel analog volume control, Panasonic film capacitors

The Q5s continues to use the interchangeable amp module design of its predecessor, and is fully compatible with all FiiO amp modules released thus far. The new standard amp balanced amp module AM3E is versatile, with 3.5mm single-ended as well as both 2.5mm and 4.4mm balanced outputs. 

Upgrades you will see even outside with the AM3E

Thanks to the flagship Qualcomm QCC5124 Bluetooth chip, the Q5S is able to support Bluetooth 5.0 which ensures a  stable, high quality Bluetooth audio experience. Various bluetooth audio codec support--such as the AAC, SBC, aptX, aptX low latency, aptX HD, LDAC,and HWA.

Bluetooth 5.0

More comprehensive Bluetooth  codec support

Massive improvement from upgraded clock management

In order to further improve sound quality, the Q5s utilizes the XMOS XUF208 USB decoding chip paired with a precise clock matching management system, allowing for support up to 768kHz/32 bit PCM and hardware-decoded native DSD – so you can be sure of excellent sound no matter what format your music is in. 

Decoding capabilities worthy of a flagship

With the upgrade to the XMOS clock management system, the Q5s has unparalleled decoding capabilities over USB, SPDIF, and Bluetooth. USB supports up to 768kHz/32bit and native hardware-decoded DSD; SPDIF supports up to 192kHz/24 bit; and Bluetooth supports up to 96kHz/24 bit (under LDAC).

Certified by multiple reputable institutions

The Q5 is: Hi-Res Audio certified,Hi-Res Audio Wireless certified,Qualcomm aptX certified,

and Sony LDAC certified.

USB decoding











The massive built-in 3800mAh rechargeable polymer lithium-ion battery is sure to be able to get you through the day in most situations.

Plentiful power reserves for constant usage everyday

In addition to USB and Bluetooth decoding, the Q5s also supports SPDIF digital input and line-in analog input. The coaxial, optical, and analog line-in input are all handled through a multifunction input port that supports up to 192kHz/32 bit.

Fully stocked on inputs

The RGB lights are a clever way of indicating the audio format – the 6 different colors quickly tell you which Bluetooth codec is currently being played through the Q5s.
*When in USB decoding mode, the RGB lights indicate sampling rate.

Exhaustive list of outputs

Standard with the Q5s is the all-new AM3E balanced amp module, with 3.5mm single-ended as well as 2.5mm and 4.4mm balanced outputs. Of course, the Q5s also supports line-out output.

Intuitively know the details with just a glance

Each input mode is represented with a separate indicator light so you’ll know where you are playing from with just a glance. Long-press the input selection button on the side to view how much battery is left according to the status of 4 LEDs. Even with tiny details like these, we put and heart and soul into making the experience better for you.

A well-designed power supply goes a long way towards achieving great sound. Alongside the numerous low-noise LDO regulators, the analog, digital, low-pass, and amplification sections of the Q5s are independently powered and isolated from each other – ensuring your music comes through as cleanly and purely as possible. 

Audiophile-grade power supply

The sandblasted all-aluminum alloy CNC chassis with perfectly rounded corners give the Q5s a suave and stout experience worthy of its position.

Exquisite finish exudes quality luxury

Intelligent craftsmanship that considers all details

The back of the Q5s is made of high-quality polyurethane leather with a feel you’ll just grow positively attached too.
The three buttons and an upgraded volume knob on the side allow for an ergonomic and tactile way to interact with your music.

Combining 2 into 1 for simpler operation

The original Q5 had a separate power button and volume knob. However, with the Q5s, turning it on and off is controlled by simply turning the volume knob past a certain point – making it more convenient and easier to use.

The hardware gain and bass boost control circuits ensures that the quality of your music doesn’t diminish while still allowing you to get your music to sound exactly the way you want it.

Get rid of battery anxiety with intelligent auto-shutdown

With the automatic shutdown function, if there is no input source or there has been no music played through a connected input source after a set time (default 10 minutes), the Q5s will automatically turn itself off, further enhancing battery life and saving energy until when you really need it.

Use it worry-free with intelligent adjustment

When connected to your computer, the Q5s will automatically adjust its charging current and rate according to smart detection of the USB port's output capability. And when connected to a phone via USB, the Q5s will automatically know not to charge and draw power from it – so you can just use the Q5s free of any worries!
*Best when used with the FiiO CL06 and ML06 cables

You no longer have to be annoyed by tiny volume imbalances between the left and right channel with ADC volume adjustment on the Q5s. The ADC curve reconstruction process effectively eliminates any channel volume imbalances that occur when adjusting the volume through a traditional analog potentiometer, and also allows for much greater precision in adjusting the volume in tiny steps.
