đŸ”¶ FiiO FH3 2BA 1DD

Well your music style is something i have no experience with, but when it comes to slam the Zen is in its own league, just keep in mind that the FH3 will have more bass in stock form than the Zen so you will need EQ to get there. Also, if you are already EQing the FH3 you will probably have to EQ the Zen even more, since it responds to EQ differently than the FH3.

I have only heard the Zen for about one hour so it is still early for solid impressions from my side, but the DD coherence is surely there.

Hello,
can you test it with this songs,
thank you,



I would also be interested in how the Zen handles Vortex - Make them Suffer
 That is a lot of speed and complexity for a single DD. Curious how it handles it.

Also @Strifeff7 thanks for introducing this song to me. Always happy to find an interesting metalcore band.

Vortex doesn’t have the cleanest low end to begin with, just worth noting, that kick is pretty loose. Elevated low end can muddle that track real quick.

This place is dangerous lol - read through a lot of this thread and couldn’t help but pull the trigger on a set. Can’t wait to see what they sound like, how they compare to the Legacy 2s and the Teas and I’m interested as to how different they might sound to me and my ears.

Will want to get a balanced cable but slightly concerned if the mmcx connection is as tight as some folk have said - other IEMs are all 2-pin - so any advice on changing without breaking something would be appreciated.

Get a mmcx removal tool like this:

It pushes the connection apart rather than pulling on if you were trying to use your hands.

yes, a comparison would be interesting,

Just wanted to give a little heads up about my experience with the FH3s.

Bought my pair on March 23rd and just a couple weeks ago the DD either died or is damaged because it sounds like the bass has been removed significantly to the point where low freqs are only reproduced on the left and is super weird to listen to.

I never really do RMAs or manufacturer returns because of the wait time but i did contact FiiO and they were open to replace them if i sent out the damaged ones back, instead i just bought a pair of Arias with 1 day prime shipping and have been enjoying them ever since.

I really liked the FH3s while they lasted but i would much rather my IEMs last more than a couple of months.

That sucks dude. Mine have been going strong ~6months. How do the arias compare?

Less bass and slightly smaller soundstage. With the FH3s i was able to tell that the highs sounded a little metalicky (?) if thats a word probably because of the BAs which i dont hear in the aria.

Overall, i’m probably gonna end up RMAing the FH3s or buying a second pair because the FH3s are truly a good IEM in my mind, just thought that QA would be a little better since i bought it roughly 8 months after release.

Yup! We call that BA timbre. Perfect description. I’ve described it as a “crunchy” character to the treble.

I was almost sold until he said, the FD3 has more midbass. I’m gonna keep my FH3.

It is not just the midbass, there is a lot that is just more in quantity on the FD3 vs the FH3. The FD3 defiantly has a much more defined V-shape to it’s sound with more of the bass energy carrying into the lower mids and a much more dramatic rise starting later then the FH3 into the upper mids/treble.

If these 2 IEMs were boxers then the FH3 would be a technical out boxer throwing precise blows and the FH3 would be a slugger of an in boxer just beating opponents with brute force.

Just a little follow up to this, i sent out my FH3s to FiiO on the 5th and today (14th) my replacement was delivered. Hearing them again when they’re fully working really puts a smile on my face, compared to the Aria for the type of music i listen to, no competition
 at all.

Customer Support wise FiiO really made a good first-impression with me about warranty, they sent me out an address in California to ship them out and a day after they were delivered i got a tracking number and an email saying my replacement would be shipped out the following day. Amazing stuff.

I listen to mostly fast-paced EDM being mostly harder styles like hardcore, some hardstyle here and there and some chiptunes for nostalgia. The amount of clarity it offers when a ton of stuff is going on is insane and miles above the Aria, and the bass which works oh so well with hardstyle kicks and hardcore basslines. Amazing IEM and im glad i can listen to them again.

I am no longer using Hiby Music app for my iem FiiO FH3. I’m using UAPP now + phone + FiiO Q3 dac-amp. With bit perfect mode (no EQ at all), the sound just gets better. I also off bass boost on Q3. The bass mid and treble, everything just perfect for me. I don’t know what else to ask. I just did tips rolling too, bought Deep Mount Radius (size XS) as per @Rikudou_Goku recommendation. It is very comfortable to my small ears, sounds good too. I also use 4.4 balanced copper cable, which enhances the soundstage and dynamics. This FH3 is really a good all rounder. This is my only iem other than Tin Hifi T5, which is inferior
