FiiO Q5S Overview

Designed for audiophiles who demand a high-resolution sound on the go, the Q5s Bluetooth DSD-Capable DAC and Headphone Amplifier from FiiO packs a multitude of features in a compact and lightweight frame. High-quality Bluetooth and DAC chipsets, multiple output for various types of headphones (both balanced and unbalanced), and other features a hi-fi person would crave are all on hand.

The Q5s allows you to listen to audio up to 768 kHz / 32-bit, handling PCM audio and decoding DSD Native for a mobile listening experience. It handle various types of protocols and formats, giving you optical or S/PDIF via its 3.5mm jack, Bluetooth for wireless streaming, and connection to your compatible mobile device or computer by means of its micro-USB port. All the cables you need for connection are included.

Upgrades over the Original Q5
What's the differences between Q5s and Q5? The Bluetooth chip has been upgraded to CSR8675, which now supports LDAC and aptX HD, and the DAC chip has been upgraded to AK4493. The front RGB indicator can indicate six kinds of Bluetooth encoding formats and indicates sampling rate and DSD when connected via the micro-USB port.

Other upgrades for the Q5s include the power switch, which is now combined with the volume knob for more convenient operation. Input switching and status indicators have been added on the side of the device and four status indicators have a power indicator function. The AM3E amp module supports 2.5, 4.4 and 3.5mm headphones and the clock system now supports up to 768 kHz/32-bit decoding. Additionally, the sandblasted all-aluminum alloy CNC chassis with rounded corners gives the Q5s an eye-catching look that's easy to hold.
Compatibility with Balanced and Unbalanced Headphones
The Q5s continues to use the interchangeable amp module design of its Q5 predecessor and is fully compatible with previous FiiO amp modules released so far. The updated standard balanced amp module AM3E provides 3.5mm single-ended as well as both 2.5 and 4.4mm balanced headphone outputs.
Robust Decoding Capabilities
With the upgrade to the XMOS clock management system, the Q5s features robust decoding capabilities over USB, SPDIF, and Bluetooth. USB supports up to 768 kHz/32-bit and native hardware-decoded DSD. SPDIF supports up to 192 kHz/24-bit. Bluetooth supports up to 96 kHz/24-bit (through LDAC).
Aluminum Alloy Finish
The sandblasted all-aluminum alloy CNC chassis with rounded corners give the Q5s a pleasing look.
Thoughtful Materials
The back of the Q5s is made of a high-quality polyurethane leather. 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 can know what the status is with just a glance. Long-press the input selection button on the side to view how much battery is left according to four LEDs.
Audio Formats at a Glance
RGB lights also indicate the audio format being played. Six different colors quickly tell you which Bluetooth codec is currently being played through the Q5s . In addition, when in USB decoding mode, the RGB lights indicate sampling rate.
Exhaustive List of Outputs
Standard with the Q5s is the updated AM3E balanced amp module. It is built with a 3.5mm single-ended balanced output as well as 2.5 and 4.4mm balanced outputs. The device also supports line-out output.
Fully Stocked on Inputs
In addition to USB and Bluetooth decoding, the Q5s also supports SPDIF digital and analog line-in input, handled through a multi-function input port that supports up to 192 kHz/32-bit.
Gain and Bass Boost Controls
The hardware gain and bass boost control circuits ensure that the quality of your music doesn't diminish while still allowing you to get your music to sound the way you want it.
Battery Life
The built-in 3800mAh rechargeable lithium-ion polymer battery can get you through the day in most situations.
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 (10 minutes), the device will automatically turn itself off.
Intelligent Adjustment
When connected to your computer, the Q5s automatically adjusts its charging current and rate according to smart detection of the micro-USB port's output capability. When connected to a phone via USB, the Q5s will automatically know not to charge and draw power from it. So, no worries.
ADC Volume Adjustment
No more tiny volume imbalances between the left and right channel. With ADC volume adjustment, the Q5s features an ADC curve reconstruction process that 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.
Compatible with USB Audio 1.0 and 2.0
You can enable the USB audio 1.0 mode to experience decoding up to 96 kHz/24-bit PCM without needing to install any drivers.
Flexibility with the FiiO Music App
With the FiiO Music app, when connecting via Bluetooth you can adjust its channel balance, select the lowo-pass filter, control the RGB lights, and customize the power-saving shutdown timer.
Certified
The Q5s is Hi-Res Audio certified, Hi-Res Audio Wireless certified, Apple MFi certified, Qualcomm aptX certified, and Sony LDAC certified.
