Begginer here! I've been messing with some of the EQ on my tangzu wan'er, trying to find my favorite tuning in order to get a nice pair of quality iem.
Anyway, I setteled on a weird m-shaped tuning, it is quite bright and clear but not harsh,and it still has some bass kicking and an overall beefiness to the sound. I'll add a picture of the graph for reference.(Its from wavelet graphic EQ, beware it is only up to 8k hertz)
The thing is I just can't seem to find any iem that has a similar graph, honestly most of the iems have a slightly wavy line throughout the bass to mid but pretty balanced and only get whacky at the very high frequencies, am I missing something? Or do I just have a weird taste?
M shape is so unpopular because letters are a dumb way of classifying sound signatures, besides "v shape".
Your EQ is pretty much a v shaped eq, scooping a lot of the mids 500-2khz and emphasizing bass and mid treble, it just doesn't look like so because you're looking at a very limited EQ window.
Where are you looking for graphs?
Just because an item has a graph that resembles a "M" doesn't mean it's going to sound similar to your tangzu wan er with that eq.
After posting here I got enlightened so yeah I kinda understand now, though I'd still love some advice on an iem. I've looked up some iems and after some research I've narrowed it down to:
-Sennheiser IE200 (and after some while get a new cable and do the tape mod if needed). -Tangzu zetian wu. -Truthear hexa. -etymotics er2xr ( although I never tried the deepfit earplugs) -letshouer s12 pro
I'm biased towards the IE200 because I like the design of them much over the bulky s12 and zetian wu
I try to strictly look at crinacle graphs but something I don't find one so I look at the squedlink.
