2. Design And Build Quality
The FD5 features a striking design, with stainless steel housings polished to a mirror finish. The smooth metal and chrome aesthetic give them an elegant, jewelry-like appearance. The construction feels very solid and substantial in the hand, with some nice weight to them despite their compact size.
FiiO has implemented some clever acoustic innovations in the FD5's design as well. This includes a front acoustic prism to control sound wave diffusion and a rear volcanic field system to reduce standing waves and distortion. The semi-open back alleviates ear pressure for improved comfort.
Overall, the build quality is excellent, with metal housings, detachable cables, and sturdy accessories that match the premium price tag.
3. Comfort
Despite their metal construction adding some weight, the FD5 are surprisingly comfortable once inserted and properly sealed. The over-ear cable design helps secure them while reducing microphonics. The angled nozzles and vented back plates prevent any ear pressure buildup.
Isolation is about average for an in-ear monitor, with some minor sound leakage but good noise blocking overall. Those with smaller ears may struggle to get a proper fit and seal due to the larger housings. But for most, the FD5 should provide a secure and comfortable listening experience.
4. Sound Quality Of The FiiO FD5
I. Tonality
The FD5 tuning targets the Harman curve, resulting in a mildly V-shaped signature. The lows and highs are slightly elevated over the midrange, adding some extra punch and sparkle. However, the sound retains good balance across the spectrum.
The overall tonality is natural and enjoyable, with no harsh peaks or recesses. Vocals have a nice presence and intimacy. Instruments sound full-bodied and lifelike. Whether you prefer a neutral or colored sound, the FD5 offers flexibility to tweak the sound with the included accessories.
II. Frequency Response Graph Of The FiiO FD5
III. Bass Response
The bass is powerful and authoritative, with excellent extension and slam. Sub-bass rumble is visceral, and mid-bass impact delivers a pleasing thump. Thanks to the dynamic driver and FiiO's acoustic innovations, the low-end is tight and articulate. Basslines sound dynamic yet controlled. Drums have realistic decay and texture. There is no muddiness or bloat hampering the rest of the mix.
IV. Midrange Performance
The midrange takes a slightly laidback position but retains clarity and detail. Vocals have a natural timbre, with clear intimacy and nuance. Male and female voices both shine through with crispness and realism. Acoustic instruments have an appropriate body and resonance. The mids are smooth and refined overall, if not as forward and vibrant as some competitors.
V. Treble Response
Treble is well-extended and airy, adding sparkle and energy to the FD5's sound. There is plenty of detail in the higher frequencies while avoiding harshness or sibilance. Cymbals shimmer brightly, and high strings are crisp and defined. The treble strikes an ideal balance of presence and non-fatiguing quality.
