The FiiO BTR3K is a portable Bluetooth DAC and headphone amplifier designed for high-quality audio on the go. Priced affordably at around $109 AUD (approximately $70 USD), it combines wireless convenience with the option to be used as a USB-C dongle, boasting a compact size of approximately 58 x 5 x 1 mm, making it easy to carry. The device features a robust aluminum alloy body with double-sided 2.5D glass for a premium feel. With Bluetooth 5.0 support, the BTR3K enables stable and fast connections, and it is compatible with various audio formats including LDAC, aptX HD, AAC, and more. Its amplification capabilities are adequate for driving headphones of up to 100 Ohms, offering 25 mW of output in single-ended mode and 78 mW in balanced mode. The integrated mic and cVc noise cancellation technology provide clear call quality. The BTR3K also excels in sound quality, particularly with sensitive IEMs, showcasing impressive detail and a good soundstage. However, it has some limitations like relatively low power output compared to higher-end models and independent volume adjustments that aren't fully supported on all platforms. The BTR3K provides an extended battery life of about 11 hours, while also allowing for simultaneous pairing with two devices.
