What's with the burn-in thingie?

I've been in this hobby since 2006 or thereabouts and literally had hundreds of sets (still have 150+) and never ever have I noticed the sound change after a period of use. Never.

I can definitely understand a device mechanically loosening up or getting to the proper tolerance needed but the drivers in IEMs are so small and light there's not much that can gain optimal elasticity or whatever else. I don't think it's measurable in IEMs, otherwise it would show up on a graph.

Not entirely related, but there was one guy on Reddit measuring his E500 after months (or year. I don’t quite remember), the FR did change quite a bit.

Fun anecdote. Anyhow, yeah we can do the experiment, but it’s quite easy to mess up the experiment procedure as a small shift in positioning of the iem in the coupler and change both FR and distortion measurements, invalidating any tiny change that burn in might make.

Final Audio does recommend you to spend some time before judging because your ears need to be adjusted to the new sound. That’s why A/B/A tests are very useful at highlighting the differences, but you need to listen an IEM by itself for a while to really “get it”.

Also not recommended,
if you wish to listen to headphones/IEMs that cost $50 and those 3k-4k,
and keeping the same excitement and enthusiasm while listening to any of them

Cheers!

Pretty sure Tyll busted the burn-in myth. He kept a pair of full-size headphones on a rig for a month or so and kept sweeping them. All he detected was a slight change in the atmospheric pressure due to time of day/temperature.

While I have measured a change in driver suspension compliance for loudspeaker drive units, the burn-in can be performed in minutes by introducing a high level signal which makes the diaphragm do a few swings near Xmax.

Here's a review of the Simgot EA500LM: https://www.head-fi.org/showcase/simgot-ea500-lm.26966/reviews#review-33124

Pros:
Decent accessory line-up
Solid build, elegant aesthetics
Comfortable
Easily driven
Above average isolation
3 tuning nozzles to bestow versatility in tonality
Well-balanced on gold/red nozzle
Excellent technicalities, good soundstage width and imaging
Natural timbre

Cons:
Mirror-like finish may be prone to smudges or scratches
Shouty/harsh on black-silver nozzle
Not for bassheads
Bass could do with a touch better texturing

I would attribute changes in the graph done by a casual like myself to user error. Measuring rigs are so sensitive to placement that even a 0.5mm in insertion depth affects the measurement.

Unless this measurement was done in a proper lab I wouldn't trust it one bit. FR graphs on Squig done by different people vary wildly in how they look, and while I could enumerate several factors as reasons for this variance and I'm pretty sure burn-in is not one of them.

I miss Tyll, I hope he's doing well this days.

Simgot EA2000

What can be said about bass according to the graph?
Lots of it, not enough, weak, strong...etc.

From what I can see/read, I would say the bass is the weaker side of the EA2000.
Is that correct?

Cheers!

I would say there is plenty of bass but that graph looks a bit weird, what's the source?

I don't know...that's what I found Googling...there are not many others...
That's why I asked...by listening to EA2000, I can feel a pretty decent bass response.
This graph doesn't seem like that.

 

[Dsnuts]

It is similar in the way it looks to the EA1000 as well but you wont read anyone that says the bass end on these are weak. Some might prefer more mid bass but thats more or less for bassheads. That passive radiator Simgot need to use more on their IEMs imo.

Little comparison between the EA500LM and the EM6L...

But before that...

1. Using a tripowin modular cable on the EM6L and a Dunu Duw-02 on the LM. I don't really buy into cables changing sound. I just switched cables as I prefer using 4.4mm and for comfort around my ears.

2. Best eartips for me - Dunu S&S on the LM and Radius Deep Mount Clear on EM6L. Tips chosen based on fit in my ear which was affected by the weight and construction of the iems as well as the nozzle size. I couldn't get a good seal and stability with the S&S on the EM6L. I also felt that the S&S kept the nozzle tip too far away from my eardrum and that little distance meant a little more sibilance. The Radius Deep Mount dialled that in by allowing a deeper insertion. There's still some bite to the EM6L with the Radius tips but at an enjoyable level for me. The S&S on the LM squeezed out as much depth of soundstage from this iem as I think is possible... Just the slightest bit of extra decay particularly vocals.

Now to the iems:

Bass: the LM is the clear winner here, greater presence impact, resolution and texture. Not that the EM6L is not bad by any means. It's just better on the LM if bass is your focus.

Mids - I enjoy both... very slightly warmer on the LM, greater clarity and resolution in the EM6L. There's not much in it.

Treble - for the trebleheads the EM6L wins out here, with the right tips and fit. The EM6L is slightly brighter and more resolving in a way that I really enjoy. The LM is less exciting but it's well controlled if you like more relaxed treble. I like both depending on my mood

Soundstage and imaging - EM6L takes it but as I said above, the S&S tips really get the best out of the LM.

Hi all,

Please find below for my experience on the EA1000 Fermat. Hope you'll enjoy the video

Thank you!
