this is a ROUGH estimate. These are all incredible iems and I would take any one of them and be a happy camper. Best bang for the buck is a used ie800, hands down. They give top notch clarity and resolution for 350ish used. a little bright but lively and engaging and laid back enough to be non fatiguing.
Best of the best-
64 AUDIO TIA FOURTE- just rocked my world- bright, incredible bass texture, detail and soundstage monsters. Like an ie800 without the treble glare, better on all fronts.
64 AUDIO U18 - Didn't compare back to back but they are like the Andromeda with better bass and somewhat less "muscly" sounding, but still engaging and punchy. Full size equivalent would be a well driven he-6 in terms of frequency. These along with the Andromeda have the most balanced frequency response, but not quite as much of a wow factor as the tia fourte, just like the andro were more even than the ie800, but lacked the wow factor.
Audeze lcd-i4- love the form factor, sound, open, iem- If I could only keep one piece of gear, this would be it. best compromise on all fronts for me
audeze- isine 10/20- 10 has a more balanced frequency response, isine 20 is noticeably warmer. cypher v1 had WAY too much presence from 1k-7k, had to eq that down all they way on the app. Maybe ive got a faulty cypher cable, but you can eq these to have the best bass besides the he1k imo.
JH AUDIO JH16V2- these have a slight treble spike but they are truly like a layla and jh13v2 had a baby- a great compromise with the slight dip from 2-5k but not as drastic as the layla, with the bite in the treble from the jh13v2 but not quite as shouty in the upper mids, but that dip takes away from the perceived detail and soundstage of the jh13v2. Also the jh line has great bass texture and extension. These actually remind me a lot of the he-1000 with a more forward punchy presentation, but very similar tuning. Someone said these are the sweet spot in the jh lineup, and having heard all the higher end but the lola, id agree. Great middle ground
CAMPFIRE ANDROMEDA- Again, these are incredibly even in the frequency response, bright but warm, not fatiguing, not splashy, just right. forward presentation but large stage. I prefer the frequency response of these to the ie800, but sometimes the imperfections of frequency response give a little more life and wow factor, which is why I ultimately preferred the ie800 even though I think the andro's are "better" if that makes sense.
Earsonics S-EM9- having a hard time deciding where to put these, great subbass, not too much midbass, super fast mids, great treble that's almost perfect. These are like how I expected the w60/w80 to sound. Take the westone series and fix the problems (too much midbass, recessed 2-5k and add a hair more treble sparkle) and you've got the sem-9. They are laid back and relaxing with a great frequency response. The fit wasn't my favorite by any means.
JH AUDIO JH13V2- I LOVE THESE. There is incredible amounds of air, and they are so precise and like a scalpel with their leading edges. There is great bass texture, great presence in the upper mids/lower treble, a nice sparkle up to about 8.5k and then a dip to avoid too much tizzyness. These are the HD800's of iems, truly. Ive compared and they are so similar, and I love them despite being a hair bright and sibilant.
SENNHEISER IE800 / IE800S- ie 800 is a little more exciting, ie800s is a little more warm and refined in the treble but still a hair tizzy. ie800 is unbeatable with classical in my opinion.
Still incredible, but there are conflicts with my preference that put them in a lower tier due to preference only-
JH AUDIO LAYLA- these are just a bit too warm for me. they are a bit more chesty in the lower mids than the jh13v2 and jh16v2, and dip just 2-3 db too much from 2-5 for me to LOVE them, but that bass is incredible, and they are sooo smooooth without losing ALL the sparkle, they just have a little too much of a dip for me. But if you like warm smooth and non fatiguing, without being too laid back in their presentation these are very very good. These really probably deserve to be higher on the list, but my preference is lively treble and these are smoooooooooooooth.
WESTONE W60- really great frequency response, a bit warm, and a bit more laid back in their presentation. IEM's like these and the layla are great to crank loud.
JH AUDIO ROXANNE PERFORMANCE SERIES- the roxannes are such a unique sound, but like the laylas they dip a bit too much in the uipper mids, and have a bit too much upper bass and lower treble to where they intrude on my preference for lively treble. these are improved over the original though, with more air and less treble spike than the originals which were quite spikey in the treble.
WESTONE W80- really similar to the jh13v2, but more laid back and less forward. The jh13v2 is more direct on the leading edges and more aggressive in the attack. These are probably a bit more warm, but have less bass than the w60
JH AUDIO JH13FP- similar to the w40 but more forward and a little less mid bass
JH AUDIO ROXANNE- great soundstage, powerful and BIG sound, but had some terrible treble spikes I really didn't like combined with the somewhat recessed upper mids.
such a hard thing to rank these, again they are all great and preference plays into things more than anything. Standouts to me are tia fourte, jh16v2, ie800, and the isines.
