FiiO /Snowsky Retro Nano Bluetooth USB DAC-versterker met LDAC, aptX Adaptive, aptX LL (3,5 mm ongebalanceerde en 4,4 mm gebalanceerde uitgang) (wit)

I am quite fond of the design. The sound quality is great and it has great Bluetooth codec support. The replaceable battery is a Li-ion 10440 cell, for which you can get replacements for easily. I don't think any other Bluetooth DAC has an easily replaceable battery, which probably makes this its most unique feature. With a battery replacement, this DAC should have a significantly longer useful lifetime compared to others.The only problem I've found is the bit depth support on USB audio. The built-in CS43131 DAC supports 32-bit audio, and when using LDAC, I can select 32-bit fine. However, on USB, it only advertises 16-bit formats. I'm not sure if this is a hardware limitation or a firmware bug.

Pensé que sería un poca más grande pero tiene un tamaño perfecto. Los materiales se sienten bien, hasta el momento todo de maravilla.

Cracking wee device. And packs a punch. Worth the money.

Love the retro design and it has worked great so far. Used it with several different headphones. Sound is great and excellent for phones without headphone outputs.

It looks and sounds great, and the removable battery is a massive bonus, these batteries are fairly cheap but remember to get a 10440 with a flat terminal, as a pointy one might not fit or will be hard to remove from the device. The triangles saying "Rev" and "FWD" are just a decoration and not touch buttons This is only a minor inconvenience because the long press on volume buttons doesn't need to be very long to register (and oddly enough volume up is skip back, and volume down skip forward). The display window seems to be either glass or some nice hard scratch-resistant plastic that feels like glass. The Bluetooth doesn't break up across the house (wooden construction, no rebar), and only breaks up when the phone is charging wirelessly and a few meters away (probably the phone's fault then). It uses the same 32bit DAC chip as the Creative SoundblasterX G6 which I also have and it sounds similar to it when both have DSP effects and EQ off (but this uses two of these DACs to make the balanced output). It drives HIFIMAN HE400SE without much problem, and can get them to be uncomfortably loud. And those are the first of my headphones that really suffer when fed from an underpowered source, even at low volumes. But now the most annoying thing about this device: usually USB connection is for better quality audio, but here it isn't the case - the Retro Nano only supports 16 but/96 or 48kbps over USB, and 32bit 44.1/96k over LDAC Bluetooth (so zero way to get 32 or even 24 bits resolution from this on Windows as it is an OS notoriously lacking in terms of any good Bluetooth codecs). Maybe Fiio will update it or release a different driver for it, but this also holds true on Android - 16 bit over USB, 32 over Bluetooth as seen on Neutron screenshots. Neutron music player has zero issues getting 32 bit audio from my SoundblasterX G6 over USB, but that's a chonky and power-hungry soundcard that I use with my PC . So it's a device software issue and not Android issue. As I said, it's probably fixable in the future if Fiio/Snowsky is willing to do something about it. Currently no Fiio website Windows drivers work with it as they are probably for other devices.
