Amazing power of 1600mW - Competing with desktop amplifiers

In desktop mode, the FiiO Q15 with balanced output can output 1600mW in the enhanced over-ear headphone mode, which is more than enough to drive various IEMs and full-size headphones..

USB / Bluetooth / Coaxial decoding

FiiO Q15 combines USB DAC, Bluetooth, coaxial decoding and other modes in one device, making it easier to connect different devices for different usage scenarios. USB: Connect to computers/phones/tablets/game consoles and other devices, support up to 768kHz/32bit PCM and DSD512 Bluetooth: Connect to phones/tablets/digital audio players and other devices, support high-resolution Bluetooth codecs including LDAC/aptX Adaptive Coaxial: Connect to CD/digital streamer/digital audio players and other devices, support up to 192kHz/24bit PCM and DSD64

AKM Flagship DAC Combo - AK4191EQ+AK4499EX

Self-developed digital cores - stable and efficient operation

The Q15 is equipped with digital components at the same level as the FiiO Q7 and uses the ARM processor to realize USB/Coaxial/Bluetooth decoding in one device, which can process digital audio signals with low latency and high efficiency. XMOS 16-core XU316: Supports full decoding of 768kHz/32bit PCM, DSD512 and MQA. TI Cortex M4 processor: Ensures stable and efficient operation of various systems Two audio crystal oscillators, asynchronous/self-adaptive dual-mode management: Accurate and stable adaptation to different sound sources and sampling rates

Full-color IPS display - visually appealing controls

The full-color IPS display makes it easy for you to view the current device status, such as current sample rate, volume, gain, and other information. An intuitive volume control helps you control the volume and easily navigate through the settings.

.

Phone mode switch - One touch

FiiO engineers have implemented a "Phone Mode" switch to make the Q15 more suitable for use with phones. When you enable Phone Mode*, the Q15 will be powered by the built-in battery and will not consume the phone's battery.

*If you need to connect to a computer, turn off Phone Mode.

.

RCA coaxial connector - Complete transmission of the audio signal

Thanks to the carefully designed internals, the FiiO Q15 also has a coaxial input. This allows the Q15 to be connected directly to digital streamers and CD players using regular coaxial cables. Perfect Size - Perfect Feel The Q15 uses AG glass for its back for the first time, which is scratch-resistant, prevents fingerprints and feels comfortable. Thanks to the 18:9 size ratio, the device is comfortable to use both in the hand and in combination with other portable devices. Whether you are simply on the go or on a business trip, you are in control of your high-quality sound.

.

Global PEQ - Adjustment to personal taste

FiiO Q15 features 7 EQ presets and 3 customizable PEQ* presets. PEQ can be used in both Bluetooth mode* and USB DAC mode*. FiiO's self-developed PEQ algorithm and user interface allow you to select the exact frequencies to adjust along with their gain and bandwidth - allowing you to fine-tune the sound exactly how you want it. *Customizable PEQ and PEQ under coaxial input will be supported by subsequent firmware upgrades. *PEQ in Bluetooth mode supports LDAC and other formats with support for 96kHz/24bit PCM. *USB DAC PEQ supports 192kHz/24bit PCM. *USB DAC EQ is controlled by the XMOS chip. When you turn the EQ on and off in this mode, the USB connection will be temporarily interrupted and automatically reconnected. Tap "Play" to restore the output.

Comprehensive protection

FiiO engineers have implemented a variety of hardware and software-controlled protection mechanisms to let you enjoy great sound without worry. Maximum volume limit to prevent hearing damage; Long-life high-temperature resistant battery + dynamic temperature-dependent charge and discharge control + charging protection + battery isolation, all of which work together to extend the battery life; Overheat, overvoltage and DC protection mechanism enables the Q15 to provide stable output power by ensuring the audio circuit works properly and ensuring the safety of the connected headphones.
