Highs are softer and more rolled off with Autumn, yet less grainy and better controlled and balanced than FD3 too.

The midbass are fairly pronounced, from instruments like the cross drum, up to the trumpets, while the general presentation is musical and entertaining.

It is the difference between a slightly warmer smoother tonality to a more resolving with better imaging for the FD3 sound that easily approaches their own FD5. Female vocal are more fowards, with better timbral balance, but male vocal are thinner yet again more clean-lean.

The sonic character is quite wet, which means that some sounds can be on the splashy side, but they are always enjoyable and never dry or congested. The pin-point precision of machinery and the delicate touch only possible by human hands come together to create a phenomenal piece in the FD3 Pro.Founded in 2007, FiiO went from being a small, chi-fi outsider, to one of the biggest companies in the audiophile world.

This makes the FD3 pretty compatible with most audio sources like Smartphone’s, Tablets or small Digital Audio Players/Mp3 players that do have in general a relative weak amplification. Executive Summary: Fiio FD3/FD3 Pro are the smaller siblings of the FD5, which has been a hit or a miss since the release depending on who you ask.There is a good amount of air between the instruments on simpler tracks, although the midbass can obscure this when it has a lot of presence in the mix. The cable is certainly better than the one found in the FH3 and furthermore if you have opted for the Pro edition then you get an upgraded silver-plated monocrystalline copper cable with interchangeable termination plugs.
