FiiO BTR25 Portable Bluetooth DAC and Headphone Amplifier GRADIENT GREEN

The FiiO BTR25 is a compact, high-performance portable Bluetooth DAC and headphone amplifier designed to deliver exceptional sound quality from wired headphones and in-ear monitors. Combining the Qualcomm QCC3095 Bluetooth processor, ESS ES9069Q digital-to-analog converter and dual ESS ES9603Q headphone amplifiers, the BTR25 brings advanced wireless audio technology and powerful headphone amplification into a lightweight aluminium-alloy enclosure.

Featuring Bluetooth 6.2 with support for aptX Lossless, aptX Adaptive, LDAC and LE Audio, the BTR25 allows compatible smartphones, tablets and other Bluetooth sources to stream high-quality audio to traditional wired headphones. A dedicated USB audio processor also enables high-resolution wired playback up to 32-bit/384 kHz PCM and native DSD256 when connected to compatible devices.

Three selectable operating modes provide convenient integration with computers, smartphones and Bluetooth audio sources. A vivid 1.3-inch colour IPS display presents playback information and device status, while the precision rotary volume control, dedicated buttons and detachable magnetic clip make the BTR25 easy to operate and carry. Both 3.5 mm single-ended and 4.4 mm balanced headphone outputs are provided.

Finished in Gradient Green, the BTR25 features a distinctive geometric design and compact dimensions suitable for portable listening. Additional conveniences include the FiiO Control app, adjustable equalization, game mode, car mode, firmware updates and comprehensive protection circuitry.

Qualcomm QCC3095 Bluetooth 6.2

The BTR25 incorporates Qualcomm's QCC3095 wireless audio processor with dual 240 MHz Kalimba audio DSPs. Supporting Snapdragon Sound, aptX Lossless, aptX Adaptive, aptX HD, LDAC and LE Audio, it provides high-quality wireless playback with compatible source devices.

Bluetooth 6.2 connectivity allows users to enjoy their existing wired headphones without being physically connected to a smartphone, tablet or other compatible Bluetooth source.

ESS DAC and Dual Headphone Amplifiers

An ESS ES9069Q DAC works alongside two ESS ES9603Q headphone amplifier chips in a fully differential audio architecture designed for low noise, low distortion and accurate sound reproduction.

The balanced headphone output delivers up to 570 mW + 570 mW into 16 ohms, providing substantial output capability for compatible headphones and in-ear monitors.

3.5 mm and 4.4 mm Headphone Outputs

Separate 3.5 mm single-ended and 4.4 mm balanced connections allow the BTR25 to accommodate a wide range of compatible wired headphones and earphones.

With output impedance below 0.3 ohms, the amplifier is designed to maintain stable performance with sensitive, low-impedance in-ear monitors.

Three Convenient Operating Modes

A dedicated three-position switch allows users to select PC, Bluetooth or Phone operation according to the connected source.

In PC mode, the BTR25 functions as a USB DAC and headphone amplifier powered by a computer. Bluetooth mode enables wireless listening using the internal battery. Phone mode provides USB DAC operation with a compatible smartphone or tablet while using the internal battery to help reduce power consumption from the connected device.

High-Resolution USB Audio

The SPV5048 USB audio processor supports PCM playback up to 32-bit/384 kHz, native DSD256 and DoP128 with compatible sources.

Driver-free USB DAC operation offers convenient connectivity for supported devices, allowing users to enjoy high-resolution wired playback without relying on Bluetooth transmission.

1.3-Inch Colour Display

The integrated 1.3-inch colour IPS display presents useful listening information, including Bluetooth codec, sample rate, volume, battery status and playback details.

Song information can also be displayed during compatible Bluetooth playback, making it easy to monitor the current listening session.

Premium Gradient Green Finish

The distinctive Gradient Green finish gives the BTR25 a contemporary appearance that complements its angular aluminium-alloy construction.

The compact enclosure features a precision rotary volume control, dedicated buttons and a detachable magnetic clip for convenient everyday use.

Smart Controls and Additional Functions

The BTR25 supports the FiiO Control app for adjusting compatible settings and sound preferences. Additional conveniences include selectable 60-step or 120-step volume control, game mode with supported USB microphone input and car mode with automatic power operation.

Firmware updates are supported through USB and Bluetooth over-the-air updating, helping maintain compatibility and functionality.
