Change modes with just one button
Due to the BTR15's ability to work as a Bluetooth receiver and as a USB DAC, we have implemented a PC/BT/PHONE mode button on it. With just a click of a button, you can quickly switch between the three different modes to match your current scenario for listening to high-quality music.
Global parametric EQ Be the master of your music
The BTR15 features a global parametric equalizer (PEQ). Through FIIO's self-developed PEQ algorithm and user interface, in any mode* 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.
PEQ notes:
- *BT mode PEQ adjustments are implemented through the QCC5125 DSP with support for LDAC and other Bluetooth formats up to 96kHz/24bit.
- *PC/PHONE mode PEQ adjustments are implemented through the XMOS XU316 with support up to PCM 192kHz.
- *PC/PHONE mode PEQ adjustments are implemented through the XMOS chip. Enabling or disabling the PEQ, USB will restart and disconnect.
Dual-core upgrade Two modes of high-res audio
The upgrades start from the heart of the BTR15, specifically the cores that power it. The BTR15 employs the high-performance combination of the Qualcomm QCC5125 Bluetooth chip = XMOS 16-core XU316 that supports stable high-res audio playback in any mode*, allowing you more ways to immerse yourself in the world of high-quality hi-res music.
Sampling rate notes:
- *BT mode supports LDAC/aptX Adaptive/aptX LL/aptX HD/aptX/AAC/SBC and other high-resolution Bluetooth formats with sampling rates up to 96kHz;
- *PC/PHONE modes support asynchronous decoding up to 384kHz/32bit PCM and DSD256.

MQA Full Decoder for master-quality sound
The BTR15 supports MQA Full Decoder*, which means the MQA decoding can be achieved in any music app. This allows for high-resolution, master-level sound quality in reasonably sized files well-suited for your mobile device.
*Supports up to 384kHz sampling rate

Dual outputs Covering all angles
In addition to the standard 3.5mm single-ended headphone output, the BTR15 also comes with the widely-used 4.4mm balanced headphone output - featuring greater contact reliability and durability compared to the 2.5mm balanced out. The dual outputs ensure you can use the BTR15 with more headphones, for more remarkable listening experiences.
