Overview
Founded in 2007, FiiO has earned a reputation as a trusted brand within the audiophile community. Renowned for producing a diverse array of audio products, FiiO consistently delivers high-quality sound solutions tailored to various budgets. With the release of the BTR5 2021, FiiO strengthens its presence in the portable Bluetooth DAC and amplifier market. This updated version of the original BTR5 features several enhancements, including an upgraded DAC chip for improved audio performance, more efficient power management, and the addition of MQA (Master Quality Authenticated) audio support.
However, it’s worth noting that MQA functionality is somewhat limited when using the device in wireless mode. These upgrades reflect FiiO’s commitment to advancing portable audio technology while catering to the needs of both casual listeners and serious audiophiles. The BTR5 2021 exemplifies FiiO’s dedication to delivering exceptional sound quality and innovative features in a compact, portable design.
Unboxing Experience: Packaging and Accessories
The packaging of the FiiO BTR5 2021 immediately sets the tone for what to expect from the device. The outer surface features a coating that creates a rainbow effect, making it visually appealing and a step up from the previous generation’s simpler packaging. FiiO neatly organizes everything inside a foam compartment, reflecting its attention to detail. The package includes a welcome addition compared to the previous model: an ABS plastic case with a clip, a USB-A to USB-C charging cable, and a USB-C to USB-C interconnect cable.
The interconnect cable, surprisingly soft and of good quality, allows for a seamless connection with various devices. The charging cable seems quite basic. The ABS plastic case works fine, but some users might prefer a more premium option like a leather case. Nevertheless, the overall unboxing experience is satisfying and aligns with the expectations set by the device’s price point.
Design and Build Quality: A Blend of Aesthetics and Durability
FiiO has a long-standing reputation for producing well-built devices, and the BTR5 2021 is no exception. The aluminum chassis gives the device a sturdy feel while maintaining a lightweight profile at just 43 grams. The front and back of the aluminum body have tempered glass, which looks elegant. However, this glass also attracts fingerprints. The glass, curved on the sides, enhances the tactile experience, though it’s advisable to handle the device with care to avoid scratches.
The anodized aluminum chassis is coated in matte black paint, contributing to the device’s sleek and modern look. The BTR5 2021 features four buttons on the right side, including a power button, a multi-functional button, and volume controls. The device places the balanced and unbalanced outputs at the top, and the USB-C input at the bottom. An OLED screen on the front provides essential information such as sample rate, volume level, and battery status, making it easy to navigate through the device’s menus.
Overall, the build quality of the BTR5 2021 is impressive, and it’s clear that FiiO has put considerable thought into the design. While the device is compact and portable, its construction feels robust enough to withstand everyday use, making it a reliable companion for on-the-go listening.
Performance and Chipset: Powering Your Audio Experience
At the heart of the FiiO BTR5 2021 is a pair of ESS Technology’s ESS9219C DAC chips, configured in a dual setup. This upgrade from the previous model’s ESS9218P DAC chips is aimed at delivering better performance and lower power consumption. FiiO opted for this particular model because the DAC chips from the Sabre series are known for their high performance and low power usage.
The BTR5 2021 also features Qualcomm’s CSR8675 Bluetooth chipset, which has been widely used in premium wireless audio products. This chipset ensures stable signal transmission and supports a variety of codecs, including AAC, SBC, aptX, aptX LL, aptX HD, and LDAC. This wide codec support allows the BTR5 2021 to deliver high-quality audio across different devices and platforms.
The device offers two output options: a 3.5mm unbalanced output and a 2.5mm balanced output. The balanced output, in particular, provides a significant boost in power, delivering up to 240mW into a 32Ω load, compared to the 80mW provided by the single-ended output. This extra power can be particularly beneficial when driving more demanding IEMs or headphones, though the difference may not be noticeable with less power-hungry models.
In terms of signal stability, the BTR5 2021 excels, thanks to the tried-and-tested CSR8675 chipset. Whether using the device wirelessly or wired, the connection remains strong, even in challenging environments such as subways or crowded areas. This stability is crucial for maintaining a consistent listening experience, and FiiO has done an excellent job in this regard.

Features and Control: A Multifunctional Companion
The FiiO BTR5 2021 is packed with features that enhance its usability and versatility. The device can be controlled via the three buttons on the right side, each of which offers multiple functions. Users can toggle between different filter types, adjust gain levels, and access various EQ presets, among other settings. The device also includes an auto-charge feature, which can be toggled on or off depending on the user’s preference.
One of the standout features of the BTR5 2021 is its USB DAC mode, which supports native DSD playback up to DSD256 and PCM up to 384kHz, as well as MQA decoding. However, it’s worth noting that MQA support is limited to wired connections due to the constraints of Bluetooth transmission. For users who frequently switch between different devices, the BTR5 2021 also offers a USB 1.0 interface mode for driverless operation, making it compatible with a broader range of devices, including older models and gaming consoles like the PS5 and Nintendo Switch.
Another notable feature is the integrated NFC module, which allows for quick and easy pairing with NFC-enabled smartphones. This convenience, combined with the device’s car mode, makes the BTR5 2021 an ideal companion for in-car audio setups. The car mode automatically powers the device on and off in sync with the vehicle’s engine, ensuring that your music is ready to go as soon as you start driving.
In addition to these features, the BTR5 2021 offers classic media controls, such as play/pause, track skipping, and voice assistant activation. The 60-step hardware volume control provides precise adjustments, allowing users to fine-tune the volume to their liking.
MQA and Audio Playback: Unveiling High-Resolution Sound
MQA (Master Quality Authenticated) has become a buzzword in the audiophile community, with some hailing it as the future of high-resolution audio. The BTR5 2021 supports MQA playback, but only in wired mode due to the bandwidth limitations of Bluetooth. When connected to a compatible device, the BTR5 2021’s OLED display will indicate when MQA is fully utilized, assuring quality.
For Windows users, FiiO provides drivers that need to be installed to fully utilize MQA with the BTR5 2021. Mac users, on the other hand, can enjoy bit-perfect audio without any additional software. When using the device with an Android device, the situation becomes a bit more complex, as Android’s native resampling can interfere with bit-perfect playback. To overcome this, FiiO recommends using the USB Audio Player Pro (UAPP) app, which allows for bit-perfect playback and supports MQA decoding.
During testing, the BTR5 2021 performed admirably with various high-resolution audio formats. It played DSD256 files without issues and handled MQA files on Tidal with ease. The ability to switch between wired and wireless modes while maintaining high-quality audio playback is one of the BTR5 2021’s strongest selling points.
Soundstage
Although the BTR5 2021 shows noticeable improvements in spatial imaging when connected via wire, it still offers a solid soundstage over Bluetooth. The device excels in delivering clear separation and precise positioning within the sound field. For example, with the Moondrop Aria, it provided a notably airy and expansive presentation, enhancing the sense of space and headroom. The Baldr, on the other hand, delivered natural imaging with a realistic scale and layering effect. With the OH10, the difference was less pronounced, offering a more balanced width between the left and right channels.
Low-End Performance
The FiiO BTR5 2021 is recognized for its smooth and impactful bass response. The bass is both punchy and detailed, offering solid impact without excessive edge emphasis, resulting in a rounded and well-balanced tonality. Adjusting the in-app EQ is often less necessary, depending on the headphones or IEMs in use. Increasing the frequencies around 125Hz and below showed minimal difference with bass-heavy IEMs but significantly warmed up and clarified models like the Moondrop Aria.

Midrange Clarity
The midrange frequencies are rendered with clarity and precision. The BTR5 2021 provides clean and accurate midrange performance, maintaining a crisp and spacious sound. The separation in the mids is well-defined, allowing for detailed expression. For IEMs with a focus on the upper mids, slight attenuation of frequencies in the 1k-4k range was effective in reducing distracting resonances.
High-Frequency Detail
The high-end of the BTR5 2021 delivers a good level of detail with a well-balanced tonality that emphasizes easily noticeable textures. Extensive EQ adjustments were not necessary, as the IEMs tested maintained a dynamic and consistent timbre throughout the frequency range.
Battery Life: Sufficient for On-the-Go Use
The FiiO BTR5 2021 is equipped with a 550mAh battery, which FiiO claims can provide up to 9 hours of playback time with the SBC codec. In real-world testing, the battery lasted around 6.5 hours with continuous LDAC playback, which is a more power-hungry codec. This battery life is sufficient for most daily use cases, and the device can be fully recharged in approximately 1.5 hours.
While the battery life is generally satisfactory, it’s essential to manage expectations, especially when using high-resolution codecs or the device’s more power-intensive features. For users who frequently use the BTR5 2021 in wired mode, the ability to toggle automatic charging on or off is a convenient feature that helps preserve battery health.
Dual-Mic Layout: Clear Communication on the Go
The BTR5 2021 includes a dual-mic layout with cVc 8.0 noise cancellation technology, which aims to improve voice clarity during phone calls. In practice, the microphones do a commendable job of isolating the user’s voice from
background noise, resulting in clear and intelligible communication. This feature is particularly useful for users who frequently take calls while commuting or in noisy environments.
