BTR7 Portable Bluetooth Amplifier

Color IPS display | High-performance DAC ES9219C*2 | THX AAA-28*2 amps
Wired+Wireless charging support 3.5+4.4mm outputs | One-click “dongle” mode
Qualcomm QCC5124 Bluetooth chip | XMOS XUF208 | Supports app control and OTA upgrade

*The BTR7 standard edition includes a Type-C to Type-c adapter cable.
*The BTR7 Apple edition includes two adapter cables, Type-C to Type-C and Lightning to Type-C.

Radiantly brilliant Color IPS display

The brand-new BTR7 features the seventh-generation mecha design language, giving it riveting looks. Its comfort-and-ergonomics optimized laminated aluminum alloy body is paired with a 1.3-inch IPS color display that is the showpiece of the BTR7. The display features a brand-new, colorful UI that presents important information such as volume, power, gain, and audio format in an intuitive way – just another part of the BTR7’s brilliance.

Control the power of sound High-performance DAC ES9219C*2

In each of the left and right channels of the BTR7 is the ES9219C, which is paired with a low-pass filter and an amplifier in a highly-optimized audio architecture that captures every last detail and dynamics in your music. And with support for MQA, your music will definitely come across clearly and boldly.

Extraordinarily bold, THX AAA-28*2 amplifiers

The BTR7 is the first portable Bluetooth amplifier to utilize 2 of the THX AAA-28 amplifiers. The FiiO R&D team had a breakthrough and was able to fit 4 channels of the THX AAA amplifiers into a compact body for a fully balanced audio design – resulting in 88% more single-ended power output and 30% more balanced power output compared to previous designs. Experience an extraordinarily bold symphony of music with the BTR7.

Wireless freedom, Qualcomm QCC5124 Bluetooth chip

Experience your music when travelling without the mess of wires! The Qualcomm QCC5124 Bluetooth chip, with its dual DSP and dual-core CPU architecture, not only ensures stable connections but also supports both high-res formats like LDAC/aptX HD/aptX Adaptive and more common formats like AAC/SBC.

Patented design Seamlessly integrated metal antenna

Befitting of its status as a high-end Bluetooth amplifier, the BTR7 adopts FiiO’s own patented seamless metal frame antenna design, which not only looks handsome but also ensures Bluetooth connections are more stable and interference-free.

All-encompassing, XMOS XUF208 control chip

When used for USB Audio, the BTR7 relies on the XMOS XUF208 chip to receive and decode audio data streams, with support up to PCM 384kHz and native DSD256. In USB DAC mode and with an MQA player, up to MQA 8x rendering is supported.

Worry-free battery life Wired+Wireless charging support

As a multifunctional Bluetooth amplifier, the BTR7 needs plenty of battery power when used throughout the day. Not only has the battery capacity been increased to 880mAh, but both wired and wireless charging supports allow you to charge in more scenarios. USB wired charging is fast and efficient, while Qi wireless charging is convenient and will automatically stop charging when the battery is full.

Widely compatible, 3.5+4.4mm dual output

Each update of the BTR series reflects contemporary trends in the personal audio world. With the BTR7, this means a 4.4mm balanced headphone output in addition to the traditional 3.5mm single-ended headphone output - for a more detailed audio experience in a jack format now widely used.

A new way to listen One-click “dongle” mode

The BTR7 can also be used as a “dongle”, acting as a wired decoder and headphone amplifier for your phone. Simply press the “CHARGE” button with one click to switch into and out of “dongle” mode. Compared to the typical “dongle”, the BTR7 does not consume your phone’s battery power while still maintaining its great sound quality and large power output.

In total control Companion app control and OTA upgrades

The BTR7 not only supports in-line controls, but also supports control done via a companion app – allowing you to operate it without even taking out the device itself! For instance, the equalizer functionality in the companion app allows you to adjust your music to your tastes conveniently from your phone/device. Through the app, the Bluetooth and system firmware can also receive OTA updates. And there are even more functions waiting for you to be discovered in the companion app!

*If the USB firmware is stable there is no need to update it, but updates can be done via a USB cable if necessary.

3. Daily usage, with earphone in-line controls
