Construction & Build

The FiiO BTR1K has a nice metal+plastic build that feels rugged but light weighted and gives the impression of being durable and rugged.

Moreover, their buttons and clip feel firm and as well-built as the whole unit – also is worth to highlight that the buttons do not wobble and offers a pleasant click feedback.

Connectivity

The FiiO BTR1K has a 3.5mm female audio connector on the top of the unit and an USB Type-C connection on the bottom.

Connecting any device through the 3.5mm jack transforms it in a Bluetooth connected unit – like headphones, earbuds, earphones, car audio systems and speakers.

Sound

It is no secret that the market is full of Bluetooth adapters that cost a few pennies but there is a fundamental difference that set FiiO Bluetooth amp/DACs such as the FiiO BTR1K and FiiO BTR3 apart from knockoff or unbranded competitors; sound quality and sound fidelity.

Through out our FiiO BTR1K soundtests, the unit showed a remarkable performance providing clean and unadulterated sound.

Sound was transmitted, processed and sent to the attach headphones conserving the same level of sound quality that could be obtained while using the headphones wired directly to the audio source.

Headphone’s sound signatures remained faithful without warmer nor thinner response and no increment nor decremented brightness and detail.

Our FiiO BTR1K frequency response measurements showed a proficient flat response with a rolling off starting just above 22kHz – this behavior was identical either in Bluetooth mode and while being used as an USB DAC.

The recommended drive ability of the FiiO BTR1K has a range of 16Ω~100Ω, a frequency response of 20-20kHz (which is logical with the rolling off above 20kHz shown in our frequency response measurements)

The FiiO BTR1K can output as much as 45mW (16Ω), 25mW (32Ω), offers a SNR of 118dB, THD+N <0.004% (1kHz; DAC mode), an output impedance <0.3ohm and a crosstalk ≥74 dB.
