Silverthorn...Kamelot

Well, generally I'd steer clear of bluetooth and noise cancelling headphones, as they sacrifice a lot in terms of sound quality. However, if you do travel a lot by plane then the sennheiser mm550-x might suit your needs. Otherwise here are some of my personal favourites and suggestions...

Well firstly, check out this link:  http://www.head-fi.org/t/478568/multi-iem-review-292-iems-compared-lime-ears-le3-and-le3b-added-07-31-13-p-740 But my personal preferences in this range is the Vsonic Gr07 mk2 or bass edition, and the Westone 2.

Hmm, personally I dislike active noise cancelling headphones, but maybe the Bose QuietComfort 15 would suit your needs, or you could just find a pair of headphones with a very good seal.

Haven't tried the IE 80's so don't know about them, but the Momentums are phenomenal for just about any genre and to me well worth the price and slightly bulky case.

Well for the DT990s I would say that an amp is pretty much a necessity.

For under $75 and a lot of bass..maybe the Klipsch S4

http://www.head-fi.org/t/478568/multi-iem-review-290-iems-compared-earsonics-sm64-added-07-23-13-p-735: check with this first:   Well you won't hear a substantial upgrade if you are only willing to pay a bit more, but here are a few possible suggestions:   Westone, Um3x or 4 Sennheiser...

Vmoda m80 sounds like it would suit you best, sounds very good with good bass. The sennheisers hd 25-1 ii also good but poorly made, and a bit out of your price range.

Well I may be wrong, but the Sol republic ultras are on ear headphones, plus they are more of a fashion accessory than a good pair of headphones. If you are looking for over ear headphones with deep bass I think the Vmoda m100 would suit you.

Well depends, personally I reckon the Westone 2 sounds the best but the Shure Se215 are significantly cheaper and the sound whilst not as good as the westones is a lot of fun, haven't tried the se315 so dunno about it,

I got a couple: Evanescence-My immortal Daniel Rice-9 Crimes Houko Kuwashima- shinkai no kodoku: not in english but an amazingly emotional anime song X Japan-Without you: They sang it to commemorate a band member who died so you know its going to be sad.

60s-Beatles 70s-Queen 80s-Bon Jovi or iron maiden 90s-Nirvana 00s-Radiohead?? dunno not too sure

Well, for me it would have to be Tarja, so sad when she left nightwish, Simone Simons from Epica or Floor Jansen, These metal singers can sing for sure!

Well the couple that I would recommend are if you are willing to spend slightly over, but well worth the price the vsonic gr07, or the etymotic research hf5. If you wanna save a little money but definately get your moneys worth I would also consider the Shure Se215, for around $100 which are...
