Wired headphones, premium wireless sound
Your favorite wired headphones deliver outstanding lossless sound even over a wireless connection.
The BTR25 is based on the highly efficient Qualcomm QCC3095 with two 240 MHz Kalimba Audio DSPs. It supports Bluetooth 6.0, Snapdragon Sound, LE Audio, and aptX Lossless for lossless Bluetooth transmission. This lets you enjoy sound quality and convenience anywhere.
Supported codecs: Snapdragon Sound, aptX Lossless, LE Audio, LDAC, aptX, aptX LL, aptX Adaptive, aptX HD, and SBC.
Golden ESS Combination with Fully Decoupled DAC and Amplifier Architecture
The ES9069Q, ESS’s flagship DAC for portable devices, works in tandem with two powerful, high-current ES9603Q headphone amplifiers in a fully differential audio architecture. The result is ample driving power with low noise and low distortion, along with finely resolved details and wide dynamic range. The DAC architecture is based on the 4th-generation HyperStream architecture.
Powerful drive at low impedance, unlocking the full potential of your in-ear headphones
The BTR25 is optimized for low-impedance, multi-driver in-ear headphones.
High-current headphone amplifiers and a high-current, LDO-regulated power supply ensure ample driving power at low impedances. The design with extremely low output impedance reduces the influence of the source on your in-ear headphones, thereby better preserving their original sound characteristics. A zoned power supply with independent voltage regulation further supports a clean, stable sound.
Three modes: PC, BT, and PHONE—easily switch between them with a slider
Listen conveniently via Bluetooth on the go, connect the BTR25 to your smartphone or tablet as a dongle, or connect it to your computer as a USB sound card. With the three-position switch, you can easily change how the BTR25 connects and draws power. This turns each of these devices into your hi-fi source.
PC (Computer Mode): Connect via USB to a computer to use the BTR25 as a DAC and amplifier. Power is supplied by the computer.
BT (Bluetooth mode): Wireless connection to your source; the device is powered by the internal battery. If a USB connection is active, the BTR25 can charge and be powered via USB.
PHONE (Phone mode): Connect via USB to a smartphone or tablet. The internal battery takes on part of the power load, thereby reducing the strain on your source device.
Less strain on your smartphone, longer playback time
The intelligent power management system adapts to your listening habits and provides up to 8 hours of battery life in both Bluetooth mode and Phone Dongle mode. From your daily commute to your next trip, you’ll be accompanied by great sound.
Great songs in your ears, track info right before your eyes
Large 1.3-inch HD display. Hear a tune you like? You can see the song info in a flash.
In Bluetooth mode, song information appears on the display; playback details and device status are clearly visible at a glance. Whether clipped to your collar or attached to your smartphone, the BTR25 is easy to read and operate. The display also features a device status indicator, screen rotation, and a bilingual menu in Chinese and English.
Sound tailored to your taste, wired or wireless
High-precision global 10-band PEQ.
Tailor the sound to match your headphones and your preferences, and get more out of every combination you try.
Both USB-DAC playback and Bluetooth playback support the high-precision 10-band PEQ. Combined with FiiO’s proprietary tuning algorithm, you can fine-tune frequency, gain, and bandwidth in the FiiO Control app or on the web. This gives you more flexibility in tuning, from bass to vocals. An AUTO-EQ interface is available in both the web and mobile versions.
Premium feel, controls right at your fingertips
Faceted, geometric surfaces create a clean silhouette and, together with the two-part front panel, give the device a smooth, natural feel in your hand. With its aluminum alloy housing and rotary and button controls, the BTR25 feels premium on the go, and everyday adjustments are more intuitive.
Clip on or attach magnetically
The removable magnetic clip.
Attach the BTR25 to your collar for Bluetooth listening or magnetically to your smartphone as a dongle. Thanks to the removable magnetic clip, you can switch between both options depending on the situation. This makes the BTR25 easier to take with you, and great sound becomes a natural part of your everyday life.
Three colors, three personalities
Choose between Black, Vintage Gold, and Green: classic and understated, vintage and elegant, or vibrant and expressive.
One of them is sure to suit you.
Powerful SPV5048 USB Audio Core
The SPV5048 combines high-quality USB audio transmission (which supports USB DAC playback up to PCM 384 kHz / DSD256), high-precision PEQ processing, an audio ADC, and a variety of control interfaces. In addition to high-resolution audio transmission, it offers robust support for display interaction, phone calls, and other smart features.
Thoughtful details for greater everyday convenience
Driverless Mode: UAC 1.0 mode enables operation with the Nintendo Switch and other devices.
Car Mode: The BTR25 turns on and off along with your car and is designed for listening on the go.
GAMING Mode: With USB microphone support for team chat, so victory is in your hands.
Dual headphone outputs (3.5 mm + 4.4 mm): The 3.5 mm output supports a CTIA inline microphone. Selectable volume control: You can choose between two volume curves with 60 or 120 steps. Mute with a double-click: A double-click on the multifunction button mutes the device for a quick conversation.
App control: The BTR25 works with the FiiO Control app. Multiple safety features: Temperature and DC output detection, as well as an adjustable maximum output volume. USB firmware updates: Firmware updates via USB continuously improve the listening experience.
