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 FD3 offers also two different Interchangeable Sound Tubes like the FD5, one bass and one balanced sound tube. If you own a variety of higher end aftermarket cables you might be better off just getting the base model and using what you have. While both the FD3 and FD3 Pro have the same cavity design and structure, the only difference between both pairs is the included cable. The FiiO FD3 has a nicely airy, bright and detailed treble presentation with a good sense of control, even with the black sound tuning tube that gives a slightly boost to the lower and upper treble regions. 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.

N6ii and R01 (mostly R01 since it adds more naturalism to the iem and also better stage) for portable on chair listening experience for the most part of the review. They fit nicely with a little pain being the stem hitting my ear, so turning it a bit forwards helped a lot. They have strong treble energy, but manage to deliver a wet character treble that's fatigue free, which can be slightly splashy at times. FD3 sounds excellent at all volume levels, with no particular preference to being listened to loud, medium or quiet.

Both on the top and the bottom are left and right color indicators, from which the blue one is on the left and red on the right side of the monitor.

The unique celluloid panel is covered with Z5D film coating glass for a pure yet fresh transparent look and the aluminum-magnesium alloy of the body makes it exceptionally light, making it easier and more pleasurable to carry around. While the outer diameter of the sound tubes is the same, the inner diameter differs for each sound tube.

Bass is certainly fuller, weightier, more tight, better controlled and layered with greater dynamic contrast and impact. Following the FH5, you have the FiiO FH7, a 4-BA + 1DD IEM which shares the same shell as the FH3 and FH5, just in a different color tone. FD3 Pro comes with a 8-strand 152-core silver-plated monocrystalline copper cable with interchangeable termination plugs, 3. When it comes to instrument presentation in this area, I can say that the FiiO FD3 shows a warmer than neutral tonality, along with a pretty vibrant, musical and smooth character.
