FiiO’s BTR7 Hi-Res Portable Dongle DAC Offers Wireless Playback

Yet another Dongle DAC. Before you feel the urge to yawn, the design and features of the FiiO BTR7 makes us think that this might be one really worth considering. The $199 USD price is also a positive development with some premium Dongle DACs going for significantly more.

A truly multi-functional device, the BTR7 offers the option of wired or wireless transfer of your audio, via either USB or Bluetooth. With support for a wide range of Bluetooth codecs, including aptX HD and LDAC, the BTR7 not only offers compatibility with multiple devices, it is able to wirelessly decode high resolution audio up to 24-bit/96kHz.

Sharing design cues with other FiiO products, such as the excellent M11S Portable Music Player that we just reviewed, the BTR7 features a 1.3-inch color screen that displays information including audio bitrate, volume level, Bluetooth codec and more. ​ 

The BTR7 is the first portable Bluetooth amplifier to utilise two THX AAA-28 amplifiers. As a result, FiiO have have been able to deliver a fully-balanced audio design, with each channel being driven separately. The BTR7 is able to deliver 88% more single-ended power output and 30% more balanced power output compared to previous models.

When it comes to audio quality, dynamic range, and overall musicality, FiiO have adopted a dual DAC chipset design for the BTR7. Featuring two ESS9219 Sabre DACs, with a 32-bit ‘HyperStream’ architecture, the BTR7 delivers a SNR (Signal to Noise Ratio) of 118dB via both the featured 3.5mm single-ended and 4.4mm balanced headphone outputs.

Alongside its ability to receive audio via Bluetooth, the FiiO BTR7 can be used in a wired configuration as a portable USB DAC/Amplifier by accessing the ‘One-Click Dongle Mode’. Simply connect your smartphone, laptop or other compatible device to the BTR7 via the USB-C cable.

One press of the charge button will allow the BTR7 to switch in and out its USB dongle mode, allowing you to enjoy audio files up to 32-bit/384kHz (PCM) or DSD256 – including those featuring MQA – in the highest quality. ​

Compared to some other USB dongles available, the BTR7 does not consume your smartphone’s battery power whilst in this mode.

In order to enable wider compatibility with different devices, the FiiO BTR7 features the ability to switch the USB to a USB 1.0 driverless interface. This allows the BTR7 to work with older devices — or devices with locked operation systems — such as the Sony PS5 and Nintendo Switch.

In addition to viewing the BTR7’s menu on its built-in 1.3-inch color screen, functions and settings can also be accessed in the dedicated ‘FiiO Control’ app, available for both Android and iOS smartphones. The FiiO Control app allows for a number of additional features, including firmware updates and a 10-Band Graphic Equalizer.
