To also actually contribute to this thread, some iems I’ve gone through in the past years in not much order (but not too old since I can’t really recall some of the older iems I’ve had, as I only really dove deep into iems in like the past 5 years ish)
InEar ProPhile-8: iem that I thought was a great balance for studio performance and casual listening, used to be my workhorse iem (sold)
Hyla CE-5: Really opened my eyes to iems for a really fun experience, extreme v shape madness (sold)
Stax 003mk2: Stax in ears that have a similar tuning to the 007, really nice overall and unique experience (still have)
Final A8000: really excellent analytical dynamic iems, very spatially impressive as well (sold)
Meze Rai Penta: got these for half off right when they came out since a friend didn’t like them, smooth unoffensive sound but well built and enjoyable enough but overpriced (sold)
QDC Anole VX: almost a mix of a monitor iem and fun casual iem, pretty well rounded and technical without being fatiguing, w shaped almost, forward and punchy, although lacked organicness at times (sold)
JH Lola: Was an impulse buy, really excellent midrange timbre, body, and organicness but overly wonky and had issues (sold)
Earsonics Grace: also an impulse, actually very pleasant and relaxing tuning, good body and tonal density for a ba setup, generally enjoyable and sounded like an improved rai penta but I didn’t feel I needed it in my collection (sold)
StereoPravada Spearphone SB7: Great deadpan neutral (perhaps more diffuse field) sound, super technical, really great sound overall, but man. The fit. It’s total shit. It’s actually painful after a few hours and I just didn’t want to wear them for that reason alone. Also picky when it comes to amps and too much of a hassle to use as iems so it left lol. (sold)
Final LAB II: A more neutral slightly midrange and treble focused iem, really really organic overall and tubes very well, very realistic (own)
Hyla Sarda: A CE5 with better technical performance and refinement, a bit more midrange prominence that makes it a good fun daily, but lacks a slight bit of the insane slam the CE5 had (own)
oBravo EAMT-1 c: Very holographic iem, super fast and quick, technical but fun, separation is pretty nuts as well, and surprisingly good coherency, very amp picky though and tonality is hit or miss (own)
MMR Thummim: Circular soundstage that I’ve never heard before in an iem, really rich warm and fun while being very technical, meaty overall, just hard to stop listening but might be too fun for some in tuning (own)
Fiio FH3: Bought for a throw away cause hype, solid for the price but nothing world bending, works well for calls since I bought a mic cable (own)
Guideray GRI: See above, but cheaper and more v shaped than warm in tuning, less technical (own)
FiR VxV: Got as a gift, honestly really good for the money, great all rounder that’s neutral but engaging, comfy and well built, not too source picky, and sounds good out of the box, pretty nice (own)
Rhapsodio Infinity MK2: Won’t comment much on this one but it’s honestly become one of my top iems I use to where I caused me to re-evaluate my collection when I got it (own)
JVC FW10000: Impulse buy, don’t have enough time with it to say much yet, kinda been sitting in the box since I got it lol
And then much more demoed lol.
Edit:
And also the tin T4 and T2, and OH10 so meh I forgot I had them lol
