I believe the FD3 and FD5 are very similar. I've heard it has tonal improvements over the FD5. The graphs look almost identical.

Not a BGGAR fan but here's his measurements.

Better & cheaper, it's a winner,

Graphs are fine but don't tell you which unit has the best sound quality.

If you learn their language and heard enough reference sets for yourself, they can speak out to you if the set fits your preferences or not (within a certain tolerance)

FD3 in the house and undergoing "burn-in" so there's not another FH5s situation with reviews and testing:

Beautiful pictures

Can't wait for mine to be delivered! Was 100 hours the recommended burn in time?

It was 200 hours with the FH5s so I am not going to take any chances and do 250 hours again with this one! Plenty of other products to test in the meantime anyway, including something else "new" from FiiO

Just got my Pros. Really, really nice package. Great selection of tips, including foams and bass-oriented options. Cable is very nice as well, and the build quality looks solid. Overall unboxing experience was positive.

Initial sounds quality impressions are good. Soundstage is larger than I expected, which may be due to the fact that the treble is a bit muted. First impression is that this has huge bass, tilted towards the midbass, resulting in almost a boomy sound. Maybe this effect will be mitigated with burn in?

Not quite as detailed as I would like. Moondrop's offerings in this price range (and lower) offer more detail in my opinion. But again, this is only a cursory first impression. I will do some A/B comparisons later.

Overall, if the sound profile matches your preference, then this is an outstanding piece of kit.

Just received my pair of regular (non-pro) FD3s. Here's my initial impressions after a few hours, using the balanced nozzle. I liked the stock tips the best. No burn-in yet. I'll post more impressions if anything changes.

• Excellent accessories, very comfortable shells, satisfying build quality.
• Sounds like a pretty balanced v-shaped IEM, slightly warm. Definitely more musical than analytical. Lower midrange more recessed.
• Natural tonality. Male and female vocals both sound great. Nice weight behind them (not airy). Female vocals are closer in the mix.
• Decent soundstage and imaging.
• Smooth treble. No noticeable peakiness or sibilance, and I'm sensitive.
• Bass is a bit on the looser side at the moment, I'll see if it changes with burn-in. Mid-bass and sub-bass seem to have a similar presence.

First time listening to a FiiO IEM and I'm impressed. I'm not a V-shaped kinda guy but these seem like a strong performer in the price bracket.

Sounds like your impressions match mine. I agree with virtually everything you've stated. I'm also more of a neutral - curve type of guy, so I prefer a little more detail and less "musicality" or warmth.

Very comfortable fit to my ears using the stock tips. But I'd like to see what I can do to adjust the sound profile a bit more to my liking. Tip rolling is definitely in the cards for me tonight.

FYI these are probably the least expensive set I have that still really benefit from a decent DAC/amp. No need to go extreme, but even something like the BTR5/Qudelix 5K help a lot compared to the average soundcard/onboard audio.

You guys 2 and 3 posts back need to put on the Treble nozzle.

 

[430633]

Yeah is there a lot of difference between the two nozzle/"sound tube" options included?

 

[DrewVz]

Let me go find out.

 

[marklivia]

Yes.

Treble nozzle turns it into a brighter sound. I preferred the balanced tuning.

Yeah I like my midrange too much to make a v-shaped IEM my daily driver. I'd say the weakest point of the FD3 is the boomy bass. If it was tighter and more textured I think it would improve the FD3's coherency quite a bit. But yeah, its 100$. I gifted it to a family member who could appreciate it more than myself.

Oh yeah, there's a difference all right. Definitely tilted the FR curve a bit. The black o-ring tube is brighter by far and tightens up the bass a little, which removes some of the boominess, with the stock tips anyway. I still need to do some rolling, but this is more promising.

Unfortunately we just lost power. No joke. So I'll have to continue the testing later.
