As the title suggests, I'm looking for a new pair of IEMs in the £300/$350 range, I currently live in the UK, but I'm set to be moving statestide for a considerable ammount of time (visiting New York, then heading to the west coast for work), and I'm looking to upgrade my se215s Current source is Fiio k3, used both with my desktop and portably with my S8 I listen to a variety of music genres, but generaly Rock/Alt rock/Math Rock/ Hip hop/ Indie, with some weirder stuff mixed in. Examples of music; Yves Tumor Death Grips, Tricot Vampire weekend, King nun Pond Still Woozy Nothing but theives I also use my iems for general everyday activities, so youtube, and films, as well as music, and playing games (mainly fps). I currently have SE215s, but I want to go for an upgrade which has a wider sound stage, and better instrument seperation (is this imaging?) as well as a slightly more even sound? I feel like the 215s are quite warm, I don't necessarily dislike this, but my main experience with IEMs and headphones have been cheap earphones that come with phones. I had KZ ZSR, but they fit terribly for me, and hurt my eyes, with the nub. Generic Samsung earphones have fit fine for me, both the newer AKG style, and the older samsung own brand style. I don't particularly have a great idea of what I like and don't like. Where I live I don't have a huge ammount of options for trying new headphones (one big box retailer in my city which mainly stocks fully wireless earbuds as their high end audio), other than amazon, which is a touch of a hassle to buy and then send back if I don't like them. I would like as little sound leak as possible, since I'm planning on using them on my commute, as well as at work, so I don't really want the person from the next cubicle to be hearing my music. I use small spinfits to get the right seal, small eartips fit fine, but anything beyond that is too much for me, and tends to fall out. Currently, I'm looking towards; FLC 8s/n/p (not sure of specific model to get -> n is an upgrade of S, but P is a cheaper version of n, with a plastic body instead of a metal body, worried about fit, S has a good ammount of reviews, but the n is less reviewed) I'm not sure about any UK/EU distributors, if any exists, but I can get them on amazon in the states, or from musicteck I'm worried about the long term longevity and any issues with repairing them if they do break, since I have heard stories of LMUE being annoying to deal with for repairs. Etymotic ER4XR, worried about fit, never really used tripple flange, and the issues I had with my shure's fitting me. Sound seems like good, though I'm not 100% sure about the sound stage instrument separation upgrades. Massdrop plus, EU Taxes rule this out for getting in the EU, though still feasible to get in the states. Worried about fit and then having to send them back if they don't quite fit right for me, seems to be a similar shape to the kz zsr in terms of having a bump on the earphones. Sound and Imaging(?) seem to be a good upgrade, but again, the fit has me worried. Sony MDR EX 8000ST, fit could be weird, might be too bassy for me, and I'm not sure about the sound leak. Otherwise seems good. Final Audio E5000, not sure either way twith theese. I've seen good things and bad things, but overall I'm not too sure. I'm more likely to prioritise better long term support and/or warranty, if an earphone sounds slightly worse, which slightly puts me off about the FLC earphones vs the rest, but like I've said, I'm not too sure what to buy. Any other recommendations for earphones in the price range would be highly appreciated. Cheers.
