Try to find Sennheisser PX100 headphones. They are much better than whatever else mentioned here. Might be little costly than others.
Skullcandys are bass heavy phones if you like low frequency then go for them.
And about the PMX60, if these are the same headphones that came free along with some Nokia phones then I would say stay away from them. Not at all musical.
If you want earphones, heard good things about Soundmagic PL series but I've not heard them so can't tell much about them. There is also Klipsch S2 which are also quite good. Also is the Senn CX300. And don't miss the Fisher Audio earphones, heard that they are also good IEM's (In-Ear Monitors). And with IEM's it's very important to get a good seal while wearing them or they sound crap.
Actually this whole music thing is of endless possibilities.
But again, as Anupji said, buy what your ears like. But problem here is that you just can't do any kind of audition here in India
OOpss, just noticedd that your budget and i guess it might be difficult to get the PX100 in that range.
BTW, you can check with this guy,
http://www.lynx-india.com/index.php?categoryID=4151 as he has lots of ear/headphones. I've purchased an earphone amplifier from him and it was a good experience (prompt delivery)..
Can you get things from US? If so then you'll have loads of options. I normally buy from US and prices are almost like half of what you'ld pay in India. For your budget you can easily get a Koss PortaPro which is one of the best budget headphones..
Soundmagic PL30 is available for 1k+shipping at eBay. I'm gonna order one now. Just an impulsive buy for experimentation, hope they'll turn out to be good . You may also try these
