I just got my hands on these 5 days ago, I'm not a big believer of burn in, but, Oh wow how they have left everything else I own behind.
The OP really meant it. This is very very close to endgame! (IF YOU DO NOT CARE ABOUT SUB BASS)
Okay, when I first got them I got really sad because the left side sounded wrong, there was absolutely no bass out of it, but as many of you may know, this sometimes happen when the drivers get stuck, you have to carefully blow and suck on directly on the driver (make sure to only blow air and nothing else) this works with every single earbud I own. The edifier h180 once got stuck for some reason, it happens from time to time to my Bang and Olufsen A8 which I used to daily drive. it happens to the original apple earbuds which Tyll from innerfidelity so highly
praised. They all got solved by sucking and blowing.
But I just couldn't believe the size of these after I did the trick. They definitely sound like, at least, ksc75 size. They sound really large, and thick. I did have to tune the sound signature to my taste, but I didn't have to touch any frequency above 1K. Yeah, THAT GOOD.
I emphazised 40Hz and lowered from 120-160Hz. from then on, a 3DB decrease with a high Q to 976 and they are now FLAT as a pancake.
There is no information below about 40Hz, but really, I'm not that much of a bass head so, I'm fine with a fine light bass.
But yeah, after about 2 hours, they do feel like even speakers are playing. Sometimes, after the song changes and there are some distant triangles playing, I think to myself if there is someone out there, they are that much realistic.
I really couldn't care less about it's driver's technology but the fact that I only had to use 4 EQ filters lightly, (I'm a big heavy user of EQ) really says a lot about this fantastic bud.
Also, $12. they arrived in 3 weeks from Ali. You should just get them to try them out, try the suck/blow trick on them and find out for yourselves.
There may be somebody that is keen on the cable, I'm not, I will definitely get me a new mmcx to use on this.
Oh, did I mention, MMCX swappable cable for only $12?
