I have both. The FH5 has good, balanced tuning but is a more forward sounding earphone vs the IT04. Vocals are highlighted a bit more so on the FH5. Some might like this but this is due to a slight peak in the 2khz range. Otherwise sound balancing is actualy done well on them. Treble has a slight dryness to it and is tuned well so not to cause any stridancy or fatigue. But it lacks a bit of sparkle in being a bit conservative. Treble is not as extended defined or as smooth/ sweet or silky like the IT04 treble. Mids do sound a bit more forward on them but it was purposfully done to highlight vocals. Layering of the mids is done well but lacks the imaging and precision the IT04 provides. Again resolution is not on par with the IT04 here.
Bass ends both are done well but the IT04 bass end is tighter is better textured and reaches the lowest of lows easier than the FH5. FH5 sub bass is a bit softer, boomier sounding and not as textured or as tight. Mid bass is a bit less than the sub bass on the FH5. Both have good impact in the bass region but neither are overly bass emphasized, both take a more balanced approach to tuning.
FH5 does isolate better than the IT04 but not by a big margin. It is a heavier earphone due to having alloy shells. Ergonomics and fit is a wash as both are supremely comfortable for me.
Stageing of the IT04 wins here as the FH5 gives off mid wide sound. The IT04 does have a wider stage and it is the definition of each of the sound regions that really separates the IT04 from the FH5. Depth wise I feel the IT04 has better depth the FH5 being a fuller sounding earphone can seem a bit up front for some recordings. No such issue with the IT04. Again much more natural sounding as a result.
I do enjoy both earphones but the IT04 is a special earphone, the FH5 is good for the price, very competitive at their price point. However It is the refinements in the IT04 that makes them special combined with that wide sound stage add one of the best balancing I have heard on any earphone and you get what clearly separates the IT04 from an otherwise good for the price performing FH5.
So is the FH5 a poor man’s IT04?
Just kidding!
