FiiO BTR5 Bluetooth Headphone Amplifier

With a suitably sleek aluminium alloy body like those of the latest smartphones, and curved glass on both the front and rear with an oleophobic layer for a silky-smooth touch while prevent fingerprint build-up, the BTR5 is a visual gem. BTR5 is FiiOs new flagship portable high-fidelity Bluetooth amplifier and with the help of Bluetooth version 5.0 the BTR5 supports high-resolution formats such as AAC / SBC / aptX low latency / aptW HD / LDAC up to 96kHz, so you can get totally portable yet have an excellent sounding setup with your current device. The BTR5’s built-in NFC also makes it very easy to connect to compatible devices with a single tap.



Audiophile-approved performance

The Qualcomm CSR8675 is a low-power Bluetooth chip with enhanced audio capabilities, such as supporting 24-bit audio processing and possessing a 120Mhz DSP, allowing it to powerfully handle various Bluetooth decoding functions with ease. Whether you are watching videos, playing games, or listening to music, thanks to this Bluetooth chip you can enjoy remarkable sound quality.

FPGA precision clock management

An FPGA, often used in high-end music players, is not only responsible for the transition and reception of Bluetooth and USB digital audio signals, but also for clock management. In the BTR5, after the Bluetooth signal is processed the FPGA greatly reduces jitter and improves signal stability, completely solving the problem of different clock rates that exist between the different part of audio architecture.

Independent dual crystal oscillator for accurate audio reproduction

With the addition of a dedicated FPGA, the 45.1584/49.152MHz dual crystal oscillators during Bluetooth and USB decoding can more accurately reproduce audio signals under various sampling rates, giving the BTR5 exceptional audio fidelity among Bluetooth amplifiers.

DAC utilized to its full potential

With its precise clock management system and being set to synchronous mode, FiiO has fully unleashed the potential of the ESS SABRE ES9218P for extremely detailed reproduction of sound. The multi-level analogue gain and digital volume are combined into a singular dual-volume adjustment design, allowing you to more precisely adjust the volume while fully preserving the dynamic range in your music. Underbalanced output with 2 DACs working in conjunction, the BTR5 is capable of 220mW output at 32 ohm and 7.6Vpp at 300 ohms.

Fully equipped to tackle USB decoding

In addition to its considerable lossless Bluetooth format support, the BRT5 is also quite the capable unit when it comes to USB decoding. Utilizing an independent XMOS XUF208 control chip, the BTR5 is capable of asynchronous audio decoding under USB Audio class 2.0. And when connected as a USB DAC through USB Type-C connector, the BTR5 can decode up to 384kHz sampling rate and native DSD.

Balance befitting of a flagship

For greater power and detailed resolution, the BTR5 features both balanced and single-ended outputs. In its truly balanced audio architecture, each channel is driven separately from the other with its own DAC and amplifier, allowing the BTR5 to bring you a purer sound with unmatched finesse and balance.



Beautiful OLED display

One display that shows all – a major feature of the BTR5 is the crisp 0.49-inch 64x32 resolution OLED screen that displays pairing, connection, call status, power status, encoding format and volume. And using the display you can bring up a menu that allows you to visually view and adjust the charging status, enable car mode, change filters and EQ, etc.

Keeps you going all-day

With a built-in 550mAh battery, the BTR5 only takes 1.5 hours to fully charge but lasts for about 9 hours! (while using 3.5mm output and AAC codec files)

Microphone with cVc 8.0 noise cancellation

While the BTR5 has a built-in omnidirectional high-sensitivity microphone, you can use an external microphone in a 3.5mm CTIA headset. When you plug such a headset in, the BTR5 will automatically recognize that you want to use that headphone and seamlessly switch microphones accordingly. And when using either set of microphones, you will benefit from the cVc 8.0 noise cancellation technology, which intelligently adjusts microphone gain and effectively suppresses background noise for crystal clear calls.

Intelligent companion with fine-tune volume

When you insert your headphones into the BTR5, it detects what type you are using and automatically adjust the output accordingly. When you unplug your headphones, it automatically pauses and goes into low-power consumption mode to save battery life. And when you plug in headphones with CTIA controls, you can use the microphones as well as the play/pause, volume and track selection controls

When you connect the BTR5 to your phone, the phone’s volume and the BTR5’s volume can be adjusted separately, allowing you to better fine-tune the volume to your needs. The BTR5 also remembers your desired volume, so you don’t have to adjust the volume to where you want it every time you use the device.

One button handles it all

The multi-function button does exactly as its name suggests – use it for; pairing, play/pause, accept calls, hung up, cancel, force pair or open the voice assistant. After disconnecting via Bluetooth from another device, simply press the multi-function button briefly to re-pair with the other device. When paired to a phone, simply double-click the multi-function button to wake up your voice assistant.
