FiiO FD3 PRO Earphones in-Ear Earbuds High Resolution 1DD Deep Bass Detachable MMCX Connector with 2.5/3.5/4.4mm Plugs DLC Black

Product Information

The balanced filter does such a great job evening out the treble some might actually miss some of that accentuated treble sparkle of the previous earphones.

Mid range is cleaner and fuller in presence, more detailed and transparent yet not as thick and textured in timbre as FD3. Construction is more comfortable too and tuning module way better both in design and tonal tweak result. Both are lightweight and fit comfortably in the ear while they share the same cable and accessories pack. Moreover, it comes with some interesting features such like an acoustic prism design, changeable sound tuning tubes and a semi acoustic open design. Bass of Autumn is cleaner, better extended, more flexible and higher in definition and transparency, yet not as physical and weighty and immature than FD3.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. FiiO FD3 Pro comes with a heavier, 8-strand 152-core Litz structure silver-plated monocrystalline copper cable with interchangeable termination plugs, with 3. The new shell looks equally good, outshining the FH5 and FH3, even if some might find the FiiO FD5 a bit too glossy.

FD3 is remarkably good with pretty much any music style, and I wouldn't say that they lag behind with any style, even Rap and Grind sounding fun and even addictive with them.

I thought the FH5s had some amazing bass and mids presentation but was debatable how the treble was tuned. Tesla magnetic flux paired with an ultra-fine copper-clad aluminium Japanese Daikoku voice coil for an amazing, powerful sound. Many years ago, the CEO of FiiO asked me about the music I was using their DAPs with, which at that point was Closure in Moscow and Dance Gavin Dance, both bands sounding amazing on FD3, especially when it comes to the overall detail they have. Bass is more extended and linear with the Aria, less punchy but with cleaner rumble and more natural resonance as well as less mids bleed. Sound is cohesive and well integrated, the benefits of the single dynamic driver, while decay seems to be a tad more rushed on the higher frequencies that sound ethereal and slightly thinner.
