I was in a similar position to you, I havent heard my headphones yet and am nowhere near as qualified as these guys but I've just purchased the XB500's and they should be arriving tomorrow. But i'll share the list of headphones that I was suggested and researched
XB500 - biggest bass, fairly cheap and probably better sound quality than Beats Solo if you have any friends who have them (and for a LOT less money)
XB700 - big bass but some seem to think the 500 is a bit better for mids and trebles, but these things are HUGE, if your staying indoors they would be fine but they aren't portable
V-Moda Crossfade LP- These look great, better than Beats imo, big bass, the cable is removable so if it breaks you can change it, comes with a hardcase about 2x price of XB500 (in UK)
Sennheiser HD25-ii - Good bass but may be uncomfortable. I have large ears and can never wear these smaller headphones but may be okay for you
Denon ADH-1100 - great sound apparently but I was a bit put off by quite a lot of reviews of poor build quality, they look flimsy but it will depend how much care you take with them
Audio Technica ATH-M50 - Big bass again, I found these around the same price as the V-Moda's these look good too and a lot of people suggested them too me, smaller than the XB500's if the 'look' of them is going to be important to you and they can fold up so quite good for portability
I was also recommended the Denon DJHP700, Audio-Technica WS55 (and WS55i - comes with a built in mic) and the AKG 518 DJ but these all looked a bit too small for my ears but if you have small ears these may also be worth a look. I must have looked at around 60 pairs of headphones in the last 72 hours and eventually pulled the trigger on the XB500's considering the price of some of the other headphones people were suggesting along side the XB500 it seemed silly for me to go for the others as I (like you) am not an audiophile these are my first pair of proper headphones, they have a big bass, they look quite unique but good in my opinion. I picked the XB500's up brand new for £44, which is about $70 considering the V-Moda is 3 times that (in the UK) and most of the others are double that it just made sense to go for the XB500's.
But i'll be honest, Im not an audiophile and I haven't even heard these headphones the above is just what I gathered (and remember) from researching online.
