hmm well i have only been burning in the ie7's for about 6.5 hours so far. ppl say i would need a lot more.
about the seal on the ie7 vs x10, heres the thing:
i dont think i necessarily have issues with the ie7, i think im just not USE to it. u see what im saying? because with the x10's i use to have, those gel tips were great, they go inside ur ear canal while the ie7's kinda close off the opening of the ear canal. the x10 tips are pointed, so they go in, the tips on the IE series are flat, not pointed, so they block out noise by sitting in front of the ear canal. i personally think im just not use to it and i keep thinking a good seal for me is that the ear tips are supposed to go inside the canal, which is what i was use to with the x10's. so its not really a matter of problem, more of a matter of getting use to something different.
about the bass...
the x10's i believe had a warmer sound signature, which i liked. since i havent burned the ie7's in for that long yet, the bass when i tried listening to them straight out of the box sounded like a stick being hit on the ground. it was quite sharp if u wanna call it that. its kinda hard to explain. according to other people, the ie7's really open up and sound a lot better after burn in. which i dont know yet because its only been about 6.5 hours. something else that i would have to accept is that, the ie7's dont have as big of an impact or punch as the x10's do. BUT, dont get me wrong, the ie7's really do have quite a big punch and impact, just not as much as the x10's i dont think. hopefully after burn in, the ie7's will have more impact/punch. the reason why i switched over to the ie7's was because i wanted something with more mids and still having good punchy bass. i really liked the bass on the x10's, but the mids were a bit recessed for my taste. and no, the bass on the ie7's dont intrude on the mids, thats why i kind of thought the x10's mids were a bit recessed was because of the bass. its a tough thing for me because i listen to rap/hip hop as well as rock/heavy rock etc. so i really wanted the best of both worlds, im pretty sure tho after the ie7's burn in, i think id like those better than x10's. the quality of bass on the x10 is very good. clear quality bass (assuming u have a good source and good quality music).
heres a little summary:
x10: excellent bass, good punch, extension, mids were OK, not bad
ie7: good bass as well, maybe not as big of punch, but definitely still suitable for hip hop/rap, mids were much better than x10.
the summary i gave on the ie7 was based straight out of the box listening. i havent listened to them yet after that, still burning them in, gonna wait a lil bit longer.
what ive read around here.....the IE6 actually has more bass (punch/extension etc) than ie7, but the ie7 is better at everything else (mids/clarity/soundstage...etc). by no means am i saying that the IE6 sucks at the mids/clarity or soundstage at all. i would assume there pretty good too.
ill prolly post up more impressions as time goes on.
