The enclosure is crafted from hot-bent curved glass on the front and back with an aluminum alloy middle frame, which provides ample protection, as well as a space-age 3D aesthetic that not only looks great, but is easy to handle. The built-in rechargeable battery lasts for up to eight hours, ensuring you can listen to music wirelessly for a long time. If your iOS or Android device doesn’t have a 3.5mm headphone jack, this can serve as a high-quality method to stream great-sounding music to your device.
Change Modes with Just One Button
Due to the BTR15's ability to work as a Bluetooth receiver and as a USB DAC, FiiO have implemented a PC/BT/Phone mode button. With just a click of a button you can switch between three different modes to match your current scenario for listening to high-quality music.
- PC: Connect as a USB DAC totally powered by the computer.
- BT: Bluetooth DAC and amp powered by the BTR15's internal battery; when connected via USB, it can be charged.
- Phone: Connect to a phone as a USB DAC dongle, powered by the BTR15's internal battery.
Global Parametric EQ
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 exactly the way you want it.
Dual-Core Upgrade, Two Modes of High-Res Audio
The BTR15 employs the high-performance combination of the Qualcomm QCC5125 Bluetooth chip + XMOX 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.
MAQ Full Decoder for Master-Quality Sound
The BTR15 supports MQA Full Decoder, allowing for complete compatibility with any music app, resulting in high-resolution, master-level sound quality in reasonably sized files well-suited for mobile devices.
Dual Curved Glass
The BTR15 features hot-bent curved glass embedded on both the front and the rear of the device, delivering an attractive 3D appearance that's easy to hold. With the aluminum middle frame and curved glass, the BTR15 is comfortable to handle, and once you pick it up, you won't be able to put it down.
0.96" OLED Display
The brilliant 0.96" OLED display provides more information with a larger font making it easy to see the device status or change settings. The display is offered in Chinese and English languages.
Dual Outputs
In addition to the standard 3.5mm single-ended headphone output, the BTR15 also comes with a 4.4mm balanced headphone output. The dual outputs ensure you can use the BTR15 with an extra set of headphones for more remarkable listening experiences.
Independent Power Supply for Amp
FiiO's engineers carefully designed an independent power supply system for the powering the dual ES9219MQ DAC and the headphone amplifier. By separating the power, the BTR15 provides low noise and high-current increasing the output 340mW of pure power, easily powering most headphones.
Comprehensive Battery Protection
Battery Isolation
- When connected to a computer and used in USB DAC mode for long periods of time, the BTR15 can stop the battery from being charged and can be totally powered by the computer, avoiding battery degradation.
