The Q5s is FiiO’s flagship bluetooth headphone DAC/Amp. Housing two top-notch DAC chips, Qualcomm’s flagship Bluetooth chip, and multiple inputs and outputs in a stylish sandblasted all-aluminum body, the Q5s is perfect for music lovers of all stripes.
Left/Right DACs
The Q5s uses an AK4493EQ digital-to-analog converter (DAC) chip for each channel, resulting in imperceptible distortion and noise. With a total harmonic distortion plus noise rating of <0.002% and a signal-to-noise ratio (SNR) of >117dB, the Q5s plays 32bit/768kHz tracks against a pitch black sonic background.
The Most Sophisticated Bluetooth Yet
Gone are the days of downsampled Bluetooth. Thanks to Qualcomm’s flagship CSR8675 Bluetooth chip, the Q5s supports all the hi-res bluetooth audio codecs: AAC, SBC, aptXLL, aptX HD, and LDAC.
Ditch the Charger
With nine hours of battery life, the Q5s can survive a flight from Boston to Seattle with a few layovers thrown in.
Six Inputs and Outputs
We never said this was just a Bluetooth DAC/Amp. With inputs for optical, coax, line-in, and USB, plus outputs for line out, 3.5 single-ended, 2.5 balanced, and 4.4 balanced headphones, the Q5s is your personal middleman for a million different listening scenarios .
