Mids and bass for the most part are not too affected with the filter change but it does affect their tonality to be slightly brighter to warmer depending The level of airiness and sparkle is on a sufficient level when I do listen to songs with strings and pianos or to soprano vocals. All in all, this is an excellent 8-strand 152-core Litz structure silver-plated monocrystalline copper cable that improve both sound and practicality.
If you are tired of too lean, cold, clinical or thin sounding IEM, the lush and energic bassy tonality of the FD3 will surely charm you with it’s musical immediacy that is everything but boring, yet cohesive in it’s balance. The FD3 offers also two different Interchangeable Sound Tubes like the FD5, one bass and one balanced sound tube. Fiio tunes with a variation of the v shaped harmonish tuning philosophy but this time around the mids do not take a step back nor does the treble stand on its own. but it also effectively protects your hearing by balancing air pressure within the FD3/FD3 Pro leading to less pressure on your eardrums.
DLC(Diamond-Like Carbon) is a highly rigid material that also has an extremely lightweight structure that reduces unnecessary vibrations and. 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. The pro version with its more resolving cable enhances upper notes on an earphone but how it sounds with the balanced filter gives by far their best sounding FD3.
TIMBRE is gently bright, with condensed texture and good density, timbral balance is cohesive in a opaque way and transparency is rather non-existent. While the FD3 Pro comes with a heavier, 8-strand 152-core Litz structure silver-plated monocrystalline copper cable with interchangeable termination plugs. The new shell looks equally good, outshining the FH5 and FH3, even if some might find the FiiO FD5 a bit too glossy.I am a glass half full type of guy and try to report the positives and negatives in a sound and try to relay that message to my readers and how a particular earphone will sound with a very eclectic music variety I listen to. Instrument have good texture, yet can be a bit blurry in clean definition and leaner in dynamic than higher range one. The faceplate of the monitor shell is one for sure one of the eye-catching highlights that the FiiO FD3 offers to the consumers. Also the Moondrop Aria you mention has been described atleast by some people as an iem that trades fun factor for technicalities resulting in a safe but sometimes not exciting sound (not my opinion as I have not personally tried the aria).
The sound guide is long and located at an anatomical and correct angle; sound insulation is obtained at a very high level. but it also effectively protects your hearing by balancing air pressure within the FD3 Pro leading to less pressure on your eardrums. Tonal balance is a bit similar with those two, but FD3 is notably more boosted in mid bass and overall more V shape and bassy in it’s presentation with less well separeted bass and more fowards and energic presentation. It is possible to hear to emotion and details such as sadness, sharpness and softness in the voice of Edith Piaf or Aretha Franklin.There is slightly fast attack and fast decay but given the congestion, separation is not much present .
Another winner from FiiO that outperforms the competition and gets highly recommended as a great entry level budget iem. 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 mids in tonal quality and presence of the FH5s but now has a much more cohesive and smoother treble than either of their previous earphones, especially their FH5s.We are spoil quite alot with wide range of accessories wich include superb pelican like protective case, 10 pairs of eartips including silicone and memory foam one and the much expected modular cable with it’s 3 different jacks (2. Pick the large inner diameter tube (black) for detailed treble, and choose the small inner diameter tube (red) for robust bass.
Great Deal
