Yup. I think much has been said about this by some of the guys who have most posted already. Though if you want a tad more advice, it would be wiser to state what sort of music you preferred as different phones have different qualities about them.
At the end of the day, as annoying as this sounds, if you do happen to have an audio shop near you, my best advice would be for yourself to go down to the shop and try out some of the gear so you have some experience and know what you are getting. Reading up can only do so much and sometimes, as someone who is new to the whole audio world, some of the terms and advice can go right over your head, like it does mine.
If I had the experience and the money to splurge for different phones and then give you better advice, I would. Unfortunately, I can't. The SE530s tend to favour someone who leans towards the jazz side of things and Sennheiser headphones tend to have a 'darker' signature. I'm basing this on the little that I've read.
