FiiO EH3 NC – Review



| 45mm Dynamic Drivers | Active Noise Cancelling | Bluetooth | NFC |

🎧 FiiO EH3 NC, the first wireless, over-ear headphone from FiiO.

The FiiO EH3 NC is the very first attempt from the brand to enter the over-ear headphone market.

The FiiO EH3 NC can be, confusingly, found also as FiiO EH3NC (without the space between the “EH3” and the “NC”). This dual naming can be seen even officially used by the brand itself and not just by resellers.

Despite the wide fame among bang for buck seekers and a large catalog of products, FiiO had never before released a full sized headphone.

The FiiO EH3NC features single dynamic driver with a diameter of 45mm, titanium-plated diaphragms, active noise cancelling tech and wireless Bluetooth 5.0 connection.

The FiiO EH3 NC is part of the many products released by the brand during 2019, including the:

Accessories & Packaging

The FiiO EH3 NC unboxing results in a nice semi-hard case, a 3.5mm audio cable, a cable organizer and a data/audio USB Type-C cable.

The unit comes inside a fairly small box packaging with a an all-dark design that is inline with most high-tier products from FiiO.




The cable of the FiiO EH3 NC is single-sided and detachable with rubberized finish and a round design – the cable has a textured feel that resembles many cables of mid and high-tier Sony headphones.

Both ends of the cables have single, stereo 3.5mm connectors with a straight form factor on the headphone end and an L-plug on the source end.

The cable is bundled with the device and enables to hear to music wired without any battery charge.

Construction Quality and Build

The FiiO EH3 NC feels light weighted but not necessarily flimsy; this is due to the main construction of plastic with a reinforced metal headband inner structure and glass back covers.

The back cover of the earcups is shiny and smooth, this is not a simple polished finish; instead, the back cover is actually 2.5D glass with a carbon fiber pattern beneath the transparent glass.

Bass & Sub Bass

The FiiO EH3 NC offer fun, punchy mid-bass right out of the box. Additionally, their sub-bass is able to reach good depth as to sound full and deep but not drowning.

Most modern tracks and genres will not have any bass shortage with the FiiO’s bass capabilities.

FiiO has aimed for an fairly energetic and entertaining sound signature with the FiiO EH3 NC – if you are an owner of the FiiO FH7, FiiO FA7 or FiiO FA1, you should not expect a bass as precise on the EH3NC.

Despite the energetic tuning, their bass does not sound too bouncy nor excessively out of control; allowing a rich and entertaining bass response yet not becoming a bass-only sounding headphone.

With an EQ there is a very important deepening of sub-bass with even slightly sub-bass rumble can be felt if EQ’ed with an extreme basshead custom EQ style.

Mid-bass will not show results as intense as sub-bass but will become fairly punchier.

Mids & Vocals

The FiiO EH3 NC mids have a warm personality with some mid-bass bleed.

The mids of the FiiO EH3NC offers relaxed deep vocals that might struggle to fight back with bass on mid-bass heavy tracks but will result in a very full-bodied midrange that can be appreciated by listeners who prefer less analytical sound and enjoy friendly and cozy lower mids.

On the other hand, higher mids of the EH3NC are much cleaner, with sufficient crispness yet not becoming harsh (at all).

The FiiO EH3 NC exhibits an odd retuning when activating it’s Active Noise Cancelling with unusual dips and bumps extending up to +/- 600Hz; which will noticeably degrade the sound quality in comparison when it’s ANC is turned off – for listening sessions when audio is a priority, we recommend to set the headphone’s ANC off.

Using an EQ, the FiiO EH3 NC will show a huge retuning potential (only with a complex custom EQ) that can reveal a miles cleaner midrange with extreme reduction of their mid-bass bleed, much more alive male vocals and crispier higher mids, all without introducing boxy mids nor harshness.




Highs & Treble

The FiiO EH3 NC highs provide very good detail retrieval and reproduction performance that is combined with pleasurably bright highs that achieve a comfortable balance between smoothness and brightness.

The spikes of the FiiO EH3NC translate into tolerable sibilance that can show up from time to time on sibilant-prone tracks but we consider their intensity to be sufficiently mild for listeners with average tolerance to sibilance.

The FiiO EH3 NC will not be the brightest headphones out there nor a clinically-styled one but will offer a pleasant experience without falling into an overly rolled-off highs and treble sound.

Applying an EQ, the highs of the FiiO EH3 NC can benefit from a massive makeover of their detail resolving power and offering, as well, a way brighter and more open sound – stronger sibilance and some piercing peaks will show up.

Thanks to the wide compatibility with modern codecs, including aptX low latency, the FiiO EH3 NC is a well-adapted Bluetooth headphone for movies and video watching without suffering from unsync’ed audio or delay.




Sound Leak

The sound leaking out of the FiiO EH3 NC will be somewhat more hearable than many average headphones, when volume settings are kept within moderate.

Their leakage will probably not be much problem during daily commuting or on normally busy cities but will not be a headphone recommended for libraries.

Sound Isolation

Passive isolation of the FiiO EH3 NC is substantially efficient with immediate partial isolation of the environment without having to crank up the volume too much, yet with some awareness of the surrounding noises.

As soon as ANC is activated, a stronger isolating capability is unleashed with a peak dB reduction reaching up to -28,2dB over their most efficient frequencies ranges and a very noticeable audible reduction of constant noises such as vents or in-flight cabin noises.

For listeners with large collection of ANC headphones, it is fair to note that some white noise can be heard when activating the ANC of the FiiO EH3NC.

The FiiO EH3 NC were not designed to offer ANC while being used through it’s 3.5mm connection but you can trick it to do it (unofficially – do it at your own risk). To do this you should: 1) Install the FiiO Music App; 2) Connect the FiiO EH3 NC to your phone through Bluetooth; 3) Open the FiiO Music app and search for the Bluetooth devices options of the FiiO EH3 NC; 4) Set the idle time setting to OFF; 5) Unpair the headphone to the phone. Now you can turn on the headphone without pairing it to any device and connect the 3.5mm cable to the headphone end and the source end, while the headphone remains powered, the ANC switch will work.

The top heading of the FiiO EH3 NC offers a generous amount of padding in comparison with many other over-ear headphones with similar design.

The cups and pads are oval-shaped with very deep profile that gives plenty of space for the ears and a soft padding with protein leather finish – as a point of reference, the cup’s depth of the FiiO EH3NC is nearly twice the Audio-Technica ATH-M50X and even deeper than the Bowers & Wilkins PX, Sennheiser HD 599 and more inline with the BOSE QuietComfort line.

Moreover, the FiiO EH3NC has removable earmuffs that can be swapped with a mesh model that offers better breathability but lower isolation.

In addition to this, the cups of the provide a wide range of tilting and rotating degrees that can, even, lay fully flat and fold for a smaller footprint while storing or transporting it.
