100+ Head-Fier
I have the H180, I think they should be sonically identical, just one has a mic and one doesn't. I'll measure it and send the files over in a bit.Would you mind sharing more graphs of frequency response measurements of earbuds?
I've been less active lately, after my laptop was stolen about a month ago. I'm on an old laptop now that has everything set up for measurements again. (measuring software is easy. the dev environment for generating autoeq files is a little picky). @cenizas and I are partnered to eventually get as many measurements up as possible, so we'll get there eventually.
I saw somewhere in earbuds roundup thread measurements of Yincrow X6 and Edifier P180 compared - they were similar. Edifier is also priced similar but is swiftly procurable on Amazon, so could be a great alternative. Would you mind taking a look if you havent already.

@cenizas, let me know if you've measured the Edifier P180 or have access to one.
I ordered both headphones a couple days ago. Yincrow is in transit... and Edifier arrived yesterday. It was a little too warm sounding with full foam covers (only set provided). I need to order some donuts. Which leads to another question: are your measurements with stock foams, and if there are alternatives like donuts provided then did you use them and do you detail that information in your measurements? Ive noticed in earbuds round up thread that rarely specific foam used is provided with the measurements.
Doesn't surprise me that the Edifiers are a tad overly warm. I'm guessing you're hearing bloated upper bass that bleeds into the lower mids? That's a super common sound profile for most of the earbuds I've listened to. It appears there are really only a handful of earbuds that are more IEM tuning friendly (bk2, me80, x6, rw9). Cenizas and I measure buds with foams on. I find that foams do not affect FR beyond 1k very much, something on the order of .5 to 1.25 dB difference at most between donuts, no foam and various brands of foams. Foams do affect bass significantly, though, and is the core of the difficulty in standardizing measurement protocols. I welcome cenizas' help especially since his measurement rig and protocols mirror my results closely.
This is probably a question for general earbuds roundup thread, but do you have a recommended aftermarket earbud foam cover make/brand particularly of the donut variety? I imagine thicker ones measure warmer, or have you found all foams to sound/measure pretty similarly besides donut vs full foam form?
Partially answered above. I have yet to test the various foams fiio includes with their em5, so it is possible that their foams could make a more appreciable FR difference. However, I'm not really motivated to invest time on the impact on foams on sound since my compensation files alter the sound much more significantly.
