Portable desktop-grade machine Q15

The Q15 features a new desktop mode, sporting a separate Type-C power connector for it. When the Q15 is connected to the PD power adapter, the Q15 will be powered externally completely bypassing the battery, allowing for a desktop-like experience even on the go.

1600mW of astonishing power Rivaling desktop amps

When put in Desktop Mode, the Q15 under balanced output is capable of putting out 1600MW in enhanced over-ear headphone mode, which is more than enough to easily drive various IEMs and full-size headphones.

USB/Bluetooth/coaxial decoding Useful everywhere

The Q15 packs USB DAC, Bluetooth, coaxial decoding and other modes all into one device, making it easier for you to connect various kinds of devices for different usage scenarios.

USB: Connect to computers/phones/tablets/game consoles and other devices, supporting up to 768kHz/32bit PCM and DSD512.

Bluetooth: Connect to phones/tablets/digital audio players and other devices, supporting high-res Bluetooth codecs including LDAC/apt Adaptive.

Coaxial: Connect to CDs/digital streamers/digital audio players/receivers and other devices, supporting up to 192kHz/24bit PCM and DSD64.

AKM flagship DAC combo AK4191EQ+AK4499EX

The 015 features AKM’s newest DAC combination – the AK4191EQ+AK4499EX. When working in tandem with the newly developed”DWA Routing Technology”, audio performance is greatly improved. The result is a more detailed, yet natural and realistic sound that makes the listener think they have been transported to the concert site.

Self-developed digital cores Stable and efficient operation

Featuring digital components on the same level as those of the FIlO Q7, the Q15 relies on the ARM processor to realize USB/coaxial/Bluetooth decoding in one, capable of processingdigital audio signals with low latency and high efficiency.

XMOS 16-core XU316

Supports 768kHz/32bit PCM, DSD512 and MQA full decoding.

TI Cortex M4 processor

Ensures stable and efficient operation of various systems.

Dual audio crystal oscillators, asynchronous/ self-adaptive dual mode management

Adapt to various sound sources and sampling rates accurately and stably.

Full-color IPS display Visually pleasant control

The full-color IPS display makes it easier for you to see the current status of the device, such as the current sampling * Tate, volume, gain, and other information. Helping you to +56 SH both adjust the volume and easily navigate through the 100% € BLUE TIE settings is an intuitive volume knob.

Phone mode switch With just one touch

FIIO engineers implemented a “Phone Mode” switch to make the Q15 better suited for use with phones. Turn on Phone Mode* and the 015 will be powered by the built-in battery, not consuming the phone’s battery. *If you need to connect to a computer, turn off Phone Mode.

RCA coaxial connector

Complete audio signal transmission. Thanks to the carefully designed internals, the Q15 also comes with a coaxial input. This allows the Q15 to be directly connected to digital streamers and CD players through ordinary coaxial cables, avoiding any losses from not using a direct connection.

Perfect size Perfect feel

It is the first time that the Q15 uses AG glass for its back panel, which is anti-scratch and anti-fingerprint with a delicate touch. Coupling with the golden size ratio of 18:9 makes it comfortable to use both when being handheld and when bundled with other portable devices. Whether you are simply on the go or on a business trip, you can easily remain in control of your high-quality sound.

Precisely designed inside Sophisticated audio circuit

5-level audio circuit, 5-level gain. A meticulously designed, complete audio circuit with DAC- IV-LPF-gain-headphone amplifier stages ensures the Q15 is capable of ample dynamic range and bringing excellent sound fidelity. The variable gain and variable voltage design maximizes the performance of the audio circuit. There are separate low-voltage low-gain and high-voltage high-gain modes, suitable respectively for IEMs and full-size headphones.

15-way digital-analog power supply

Extensive energy storage. Inside the Q15 is a 15-way digital-analog power supply, with power supply systems for the digital portion, analog portion, headphone amps, etc. 21 low-noise LDOs are distributed for accurate regulation, and 35 low-resistance tantalum capacitors distributed for abundant energy reserves.

High-precision and low-noise

An expert in audio restoration. FIIO engineers specially selected 60 1% precision, low- temperature drift resistors, and 28 wide temperature range NO capacitors for the Q15, allowing it to faithfully reproduce high-quality audio with the utmost fidelity even in the most demanding conditions.

Global PEQ

Adjust to personal taste. The 015 comes with 7 EQ presets and 3 customizable PEO* presets. PEQ can be used in both Bluetooth mode* and USB DAC mode*. Through FIlO’s self-developed PEQ algorithm and user interface, you can choose the exact frequencies to be adjusted along with their gain levels and bandwidth – allowing you to fine-tune the sound to exactly the way you want it.

*Bluetooth mode PEQ supports LDAC and other formats, with support for 96kHz/24bit PCM.

*The customizable PEQ will be supported through subsequent firmware upgrades.

*USB DAC PEQ supports 192kHz/24bit PCM.

*USB DAC EQ is handled by the XMOS chip. When turning on and off EQ in this mode, the USB connection will temporarily disconnect and automatically reconnect. Tap “play” to restore output.

Comprehensive protection Comprehensive peace of mind

FIIO engineers have implemented a multitude of hardware and software-controlled protection mechanisms, allowing you to enjoy great sound without worries.

Max volume limit, to avoid hearing damage; Durable high temperature resistant battery + dynamic charge and discharge temperature-based control+ charging protection + battery isolation, all work together to prolong battery durability; The over-heating, over-voltage, and DC protection mechanism allows the Q15 to stably output power by ensuring the audio circuit works properly and ensures the safety of the connected headphones.
