Due to the BTR15’s ability to work as a Bluetooth receiver and 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 modes to match your current scenario for listening to high-quality music.
The BTR15 features a global parametric equalizer (PEQ). Through FIlO’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.
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 and 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.
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.
With the BTR15, FIlO uses hot-bent curved glass for the first time – embedding it on both the front and the rear of the device. Not only does this make the device easier to hold, but it also gives the BTR15 a more attractive and 3D appearance. Together with the aluminium alloy middle frame, they make the BTR15 a comfortable device to handle – you won’t be able to put it down once you pick it up.
See all the info with just a glance Like its bigger brother the BTR7, the BTR15 also features a large display – a brilliant 0.96-inch OLED display. This display not only allows displaying more information at once, but it also allows for larger display fonts – making it easier for you to see the device status and
change various settings. Moreover, it is the rarely seen device that supports bilingual languages, Chinese and English, among similar
products.
Electricity is the mother of sound. Feiao engineers have carefully designed an independent power supply system for DAC ES9219MQ built-in earmuffs so that earmuffs no longer share the power supply with DAC and the power supply is purer. In addition, the uniquely designed external power supply has the characteristics of low noise and high current, which increases the balanced output power of BTR15 by 40% to 340 mW and can easily meet the needs of portable use.
You don’t have to use the 4.4mm balanced output to enjoy the benefits of increased output power. To improve the performance of the BTR15 in
every aspect, FIlO connected the headphone outputs in parallel to also greatly increase the output power of the 3.5mm single-ended output to better drive low-impedance headphones, allowing you to better unlock their potential.
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.
To alleviate concerns about battery health, FIlO engineers have implemented several software and hardware measures to comprehensively protect the BTR15’s battery.
