The FiiO BTR17, a remarkable new entry in the world of high-fidelity personal audio, offers a distinctive sonic profile that stands apart from typical offerings in the portable DAC and headphone amplifier market. While its character may not appeal to every audiophile, those who appreciate its unique sound signature alongside its exceptional versatility will undoubtedly find it an utterly captivating device.
Despite its remarkably compact dimensions, this FiiO BTR17 unit is densely packed with advanced functionality, boasting specifications that belie its diminutive physical size. It features state-of-the-art Bluetooth 5.4 with comprehensive codec support, dual ESS ES9069Q DACs for superior digital-to-analog conversion, an impressive power output for a portable device, and the capacity to handle extremely high-resolution digital audio files, alongside both balanced and unbalanced headphone outputs. This robust design underscores FiiO’s commitment to delivering a truly high-performance wireless audio solution.
The impression of meticulous engineering only strengthens upon experiencing the FiiO BTR17 in operation. While there are subtle qualitative differences when using it as a wireless receiver compared to a hard-wired USB dongle, the core sonic essence remains consistently engaging. Across various listening scenarios, the device maintains a character defined by its speed, insightful detail, and precise control, resulting in a profoundly satisfying and revealing listening experience that elevates your hi-fi audio.
Unlike some other DAC/headphone amplifier devices that deliver a “muscle-bound” sound, the FiiO BTR17 is akin to a nimble greyhound. It exhibits a naturalistic momentum and a compelling rapidity to its sound, whether receiving digital audio via Bluetooth or its USB-C connections. This allows tracks to flow with an infectious energy, presenting rhythms with unwavering conviction and ensuring the music stays dynamically on the front foot, without ever feeling forced or artificially propelled.
A significant contributor to this agile sound is the FiiO BTR17’s adept handling of the leading edge of low-frequency information. Instead of any discernible overhang or blurring, the device precisely snaps into bass notes with genuine purpose and clarity. While it offers a swift and direct listen, it’s important to note that its low-end presence is not overtly “chunky.” Attempts to alter its fundamental character through in-device EQ settings or filters tend to yield minimal benefit, often compromising its inherent speed and rhythmic integrity.
For a product genuinely designed for portability, the FiiO BTR17 prioritizes functionality within a minimal footprint. Its understated 87 x 41 x 16mm dimensions and 73g weight contribute to an unremarkable yet highly practical aesthetic, available in black or blue finishes. However, its build quality is commendable, with a reasonably tactile, predominantly plastic chassis that feels robust and engineered for durability, typical of quality audio tech.
Navigation through the device’s menus is intuitive, managed by a tactile rotary control that also integrates volume, play/pause, and telephony functions. Additional, albeit small, controls line the side, enabling mode selection (Bluetooth, phone, PC) and toggling “desktop” mode. Connectivity is versatile, featuring two USB-C slots for charging and data, one of which also serves as a power input for desktop use. At the opposite end, both 3.5mm unbalanced and 4.4mm balanced headphone outputs are conveniently located.
Assessing the true value of the FiiO BTR17 extends beyond its physical size; it encompasses its expansive functionality and exceptional performance. Many portable DAC and headphone amplifier solutions in its price bracket lack wireless capabilities, a dedicated display, or a companion control app. Furthermore, few can match the sonic alacrity and engaging presentation that the BTR17 consistently delivers, making it an outstanding proposition for those seeking premium portable hi-fi audio.
During extensive testing, the FiiO BTR17 proved its mettle across various setups: as a desktop DAC/headphone amp with an Apple MacBook Pro, a wired connection to an iPhone 14, and seamlessly via Bluetooth to a smartphone. It even served as a crucial link in a car lacking wireless connectivity, demonstrating its remarkable versatility. In every scenario, regardless of connection type or musical genre, this compact FiiO BTR17 consistently provided a speedy, revealing, and deeply enjoyable listening experience, confirming its status as a tour de force in portable audio tech.
