you want clarity in that price range it kinda hard TBH.
Go for the XP-3 since it's the best one i heard so far when compared to the rest of the ones within your consideration, but if you're willing to stretch your budget the SE215 would be my most recommended choice.
also if you're using exclusively for working out then go for the CKP200, it's much better at holding itself on your ear then the 300 and it sounds almost similar

Do you have a smartphone?, better off with one then buying a totally new player, especially from sony but if you still want a player then by all means go for the sony or the sansa clip
the SE215 is a VERY good starter, i can say that honestly because i myself started off with it and i'm still using it till now
if you want a better sounding but less durable starter you can go and try out the Hippo Pro one or the Phonak Audio 022

Wah, SE215 cable fragile, you sure? in my experiences it's one of the most durable in the business

less then rm100
that's gonna be a problem
up your budget a little then can get V-Sonics GR02-B, Audio Technica Sports line or Sennheiser CX series in ears
or you can try the Monoprice 8320, heard a lot of good stuff about it link


Audio Technica CKM-500i but it's slightly over your budget by rm40-50

shipping to malaysia might pop a hole in your pocket

Big post here!
Go for the Beyerdynamic MMX1 its 250+ and the mic is made by beyer so it's top notch
if you want cheap then Logitech's are quite good for the price

Audio Technica CKM500i, its actually below your budget, pretty balanced sound but don't go expecting much out of it
Klipsch S4i, not really recommended because IMO they sound awful for the price, bassy and muddy as heck but they have a mic and the Klipsch name and you could possibly like the sound
SE215 with Mic Upgrade cable, Pricey but worth every penny, Most people say they are bassy but IMO they are actually quite balanced
IEM MICROPHONES DO NOT WORK WITH LAPTOPS BECAUSE OF DIFFERENT JACKS, the IEM will work but the mic will not

Go for the Superlux headphones or the Logitech G Series
IMO the only Computer peripheral company that actually makes good headphones is Logitech but if you wanna get the Ceres then better go and try first

Try out the Grados and the Alessandros but they are open back cans so you need to listen to them in a quiet environment but other than they have the best bang for the ringgit!

1st set can recommend you the superlux headphones not sure which to recommend since all of em are pretty good for your usage
second set you can go and try out the Audio technica sports series, which one you'll have to go try for yourself since they have all kinds of fits to see which one fits you the best
