Fir Audio Thread - Discussion and Impressions

I wonder a bit if I should have gotten the modules. But I guess If wanted I could just EQ low end a bit for the same general effect. Too late to get modules now!

to be honest I would have been just fine without the modules and the -13 one hard fitted as i like that one the most and probably wont ever go for more bass, but it’s nice to have the choice for only $150 extra with the modules included.

I didn't know the driftwood faceplate is translucent which is really cool cause you have the wood and then a set of see-through stripes in between the solid wood to give you a little peak inside and it brings a nice detail and contrast to the look imo

Two ways :

- you make classic physical earprints and then you ask to the audio specialist to scan the earprints and send them to you by e-mail.

- Or you find a place where they have a 3d ear scanner. It is still very rare but it exists. Then they are able to scan directly you ear canal with laser.

I did both and I obtain far better results with a scan of physical ears prints.

3d ears scanner it is hard to manipulate and made for medical audio stuffs no really to make in ear monitors... That's why.

So call to all audiologists places around you and find one with a 3d scanner. then you're good.

I had this discussion with a few 3d ear scanner companies that a core component to the systems that’s missing is capturing ear compression. Some have very soft ears and some have stiff canal walls. When material is injected it captures the natural compression of the canal walls. I will always recommend a good silicone impression and 3d scanning of the silicone.

interesting insight from someone who builds these things.

it's satisfying to see that this is the level of thought going into totl products.

m5 is definitely up there with the best to my ears.

Just an important info :

I experience the universal Fir audio M2/3/4/5 and all I have to say for the M5 is the custom will offer really better performance, as far as I prefer my custom M5 by far comparing to the M5 universal in terme of intensity and impact. A friend who tried the M5 universel and successfully fit my custom prefered the custom version by far.

I would suggest to Bogdan to create an universal demo version of the M5 with a bigger shell to be closer to the real custom performance.

As far as it is a tubeless tech, the size of the shell works like an resonnance chamber, this is what i feel. My shell space is probably 2 times bigger than the universal, I feel more impact, more intensity, more space.

I want to say that if you want to buy M5, definitely goes to custom. I do not know if it will be the same for M2/3/4 but for M5, custom is the way to go.

This is my choice after a marathon auditioning session at @Music Sanctuary . I felt that the m3 was the best value of them all. M2 was slightly too warm and smooth for my taste, making it a nice choice for artists choosing a stage monitor that is less fatiguing. M3 was Goldilocks for both value and sound, presenting a more exciting sound, more of a very slight U shape, with (still) very present and enjoyable mids. M4 is the most midcentric, with the most forward vocals, being more of an n shape compared to the m3. I didn't like it as I felt it was not an allrounder enough to be my last iem for the next 5 years. I think vocal lovers will enjoy the heck out of it. The M5 was the m3 on steroids. Way better technicalities and slightly better engagement at the expense of a slightly more recessed midrange. However, I couldn't justify spending that much for an iem at this point of time in my life. In short, if you're on a budget, m3. If price is not an issue, M5 . If M5 miss too recessed, m4. That's all folks xD

2 time bigger ! ! Doesn’t this BIG shell in your ear create inconfort ?

I gave-up using my Roxane Custom (1st gen) because there were really too big on my ear, like a mushroom, and went to the Shure KSE1500 which fit entirely INSIDE my ear and this is VERY confortable to wear.

for me the smaller an IEM, the more confortable !

I think you do not imagine how small the M5 universal is . My ears are not big but the size of the shell is big and so the space inside is 1.5/ 2 times bigger and goes a bit out of the concha. Most comfy custom ever by the way.

100% agree.

I personally find the fit of the universals perfect
I run with them in and have had no issues, except for muscle soreness from running too fast too long. I just get caught up in the music
