FiiO Q15, the ultimate boost for your headphones

The FiiO Q15 is a portable amplifier/DAC with two power modes, notable for its output capacity of up to 1600mW. It incorporates Bluetooth technology from Qualcomm QCC5125+XU316 and an advanced AKM DAC combo with AK4191+AK4499EX to deliver exceptional sound at any volume.

This model from FiiO's new "Q" series also features a full-color IPS display, keeping you informed about the details of your favorite music.

The Q15 introduces a new desktop mode with a dedicated Type-C connector, allowing continuous use connected to a PD power adapter without draining the battery, ideal for a desktop setup even on the go.

Incredible power and high-end DAC

In its desktop mode, the Q15 outputs 1600mW for over-ear headphones, enough to drive several IEMs and full-size headphones with ease.

Uses the latest DAC combination from AKM: AK4191EQ+AK4499EX. Combined with the innovative "DWA Routing Technology", it significantly improves audio performance, delivering detailed, natural and realistic sound, transporting the listener to an authentic live concert.

Versatility in multiple scenarios

The FiiO Q15 integrates connection modes such as USB DAC, Bluetooth and coaxial in a single device, making it easy to connect to various types of devices depending on the usage scenario.

- USB: Connection with computers, phones, tablets, video game consoles and more, supporting up to 768 kHz/32-bit PCM and DSD512.

- Bluetooth: Compatible with high resolution codecs such as LDAC and aptX Adaptive.

- Coaxial: Connection with CDs, digital streamers and digital audio receivers, supporting PCM up to 192 kHz/24 bits and DSD64.

Advanced digital cores

The Q15, similar in digital technology to the FiiO Q7, uses a robust ARM processor to handle USB, coaxial and Bluetooth decoding efficiently and with low latency.
