FiiO Q5s Bluetooth 5.0 AK4493EQ DSD USB DAC Headphone Amplifier Q5s for iPhone/computer/Android/Sony

  • Chewing through formats with ease packing dual AK4493EQ chips

    The extremely powerful flagship DAC and amplifier has once again set a new bar in performance. The Q5s employs a dual DAC design, with the left and right channels each quipped with a next-generation AKM AK4493EQ DAC chip – with its lower distortion, higher signal-to-noise ratio, and greatly more refined mids and highs.

    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 pto 768kHz/32Bit PCM and hardware-decoded native DSD – so you can be sure of excellent sound no matter what format your music is in.

    Bluetooth 5.0 more comprehensive Bluetooth codec support

    Thanks to the flagship Qualcomm CSR8675 Bluetooth chip, the Q5s is able to support Bluetooth 5.0 which ensures a stable, high quality Bluetooth audio experience. Various Bluetooth audio codec are support– such as the AAC, SBC, aptX, aptX low latency, aptX HD, LDAC, HWA.

    Audiophile-grade power supply

    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.

  • 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.

    Upgrades you will see even outside with the AM3E

    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.

    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/32Bit; and Bluetooth supports up to 96kHz/32Bit(under LDAC).

    Exquisite finish exudes quality luxury

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

    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.

    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.

    Looking forward to turning on the lights

    The RGN light are 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.

    SBC: Blue light flashing

    AAC: Cyan light flashing

    LDAC: White light flashing

    LHDC: Green light flashing

    aptX/aptX LL: Purple light flashing

    aptX HD: Yellow light flashing

    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 output. Of course, the Q5s also supports line-out output.

    Fully stocked on inputs

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

    Find your rhythm with gain and bass boost controls

    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.

    Plentiful power reserves for constant usage everyday

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

    USB decoding: >9H

    COAX: >10H

    AUX: >25H

    Bluetooth: >9H

    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 on, further enhancing battery life and saving energy until when you really need it.

    Use it sorry-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

    Combining 2 to 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

    Say goodbye to imbalance with ADC volume adjustment

    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.

    No need to install drivers fully compatible with both USB audio 1.0 & 2.0

    For ultimate convenience, you can simply enable the USB audio 1.0 mode to experience decoding up to 96kHz/24Bit PCM without needing to install any drivers (Press and hold the previous track button, then connect via USB to start USB audio 1.0 mode).

    Discover more flexibility with just a few taps

    With the FiiO Music App, after connecting the Q5s via Bluetooth you can adjust its channel balance, select the low-pass filter, control the RGB lights, and customize the power-saving shutdown timer.

    Certified by multiple reputable institutions

    The Q5s is: Hi-Res Audio certified, Hi-Res Audio Wireless certified, Apple MFi certified, Qualcomm aptX certified, and Sony LDAC certified.
