The FiiO BTR25 turns any pair of wired headphones or in-ear monitors into a high-resolution wireless setup. Clip it to a pocket or bag, pair it with a phone, and it receives music over Bluetooth 6.2 and feeds it to a proper headphone amplifier, so your wired headphones gain wireless freedom without the compromises of a built-in phone output. It joins FiiO's long-running BTR range of Bluetooth receivers, which also includes the BTR13 and BTR17, and this listing is for the Black finish.
Wireless Performance
At the heart of the BTR25 is the Qualcomm QCC3095 Bluetooth chip, bringing Bluetooth 6.2 and support for the aptX Lossless, LDAC and LE Audio codecs. aptX Lossless allows CD-quality audio to be transmitted without loss from a compatible source, LDAC provides high-resolution wireless from Android phones and players that support it, and LE Audio brings the latest Bluetooth low-energy audio standard.
DAC and Amplifier Architecture
Decoding is handled by an ESS ES9069Q DAC, feeding a pair of ES9603Q headphone amplifiers. FiiO states that the design delivers low noise, low distortion, excellent detail and dynamic sound, with the balanced output rated at up to 570mW + 570mW into 16 Ohms. Both a 4.4mm balanced output and a 3.5mm single-ended output are provided. In PC mode the BTR25 also works as a USB DAC, decoding PCM up to 32-bit/384kHz and native DSD256 from a computer.
Three Modes and Everyday Usability
A three-position switch selects between PC, Bluetooth and Phone modes with a single touch, so the same unit serves as a USB DAC for a computer or phone, or as a Bluetooth receiver. A 1.3-inch colour display shows track information in real time, and a volume wheel with physical media buttons keeps everything within reach. The detachable magnetic clip makes the BTR25 easy to carry and attach, and the CNC-machined aluminium alloy chassis keeps it light yet solid. Battery life is rated at up to 10 hours of Bluetooth playback. The FiiO Control app adds a 10-band parametric EQ for tailoring the sound to your headphones.
Finishes
The BTR25 is available in three finishes: Black, Vintage Gold and Gradient Green. This listing is for the Black version.
