The FiiO BTR15 is FiiO's new DAC/Amp dongle with Bluetooth and balanced 3.5mm and 4.4mm headphone connection to take advantage of all the benefits of high-quality portable audio. 

As a novelty, the BTR15 integrates a side button that allows you to switch between the different modes of use and a 0.96" OLED screen that shows everything that is happening at the moment on the device, all with a power of 340mW.

Following the aesthetics of the previous versions, the BTR15 also has a double curved glass design, for a perfect grip and the possibility of transporting it wherever you want.

Due to the BTR15's ability to function as both a Bluetooth receiver and a USB DAC, the FiiO team has developed a PC/BT/PHONE mode button. With the push of a button, you can quickly switch between the three different modes to adapt to your current scenario and listen to high-quality music.

This FiiO BTR15 incorporates 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 exactly to your liking.

The improvements start at the heart of the BTR15. Specifically in the nuclei that feed it. The BTR15 employs the high-performance combination of Qualcomm QCC5125 Bluetooth chip and a 16-core XMOS XU316 processor that supports stable playback of high-resolution audio in any mode, allowing you more ways to immerse yourself in the world of high-resolution music.

The BTR15 isMQA Full Decoder compatiblewhich means MQA decoding can be achieved in any music application. This allows for master-level sound quality in reasonably sized files suitable for your mobile device.

With this DAC/Amp dongle, FiiO uses hot-curved glass for the first time, both on the front and the back of the device. This not only makes the device easier to hold, but also gives the BTR15 a more attractive, three-dimensional look.

Together with the central aluminum frame, all the chosen materials make the BTR15 a device that is comfortable to handle and perfect to look at.

Like its older brother, the BTR7, this BTR15 also has alarge 0.96-inch OLED screen. This screen not only allows more information to be displayed at once, but also allows for larger display fonts, making it easier to see the status of the device and switch between various settings.

In addition to the standard 3.5mm headphone output, the BTR15 also includes the 4.4mm balanced output. Dual outputs ensure you can use the BTR15 with more headphones, for extraordinary listening experiences.

The BTR15 mounts an ES92219MQ DAC and an exclusively designed external power supply with low noise and current, increasing the balanced output power by 40% up to 340mW.

For its part, FiiO connected the headphone outputs in parallel to also greatly increase the single-ended 3.5mm output power and be able to effectively drive the low-impedance headphones to unleash their full potential.
