Bose are horrible, I auditioned the Triports today.
Anyway, for someone actually on a budget:
Koss KSC-50s - I don't know what everyone has against these, it took a while to figure out how to put them on, but I found out that if you pull your ears through the clip after putting them on, they stay completely secure.
That and you can stretch the clip over the phone to make it tighter.
Retails for 18 at Best Buy, cheaper online.
I have sportapros too, but KSC-50s sound the same.
Sennheiser HD202s - Haven't heard anything about these in a while, probably because they're cheaper than 100 bucks. :P
They're excellent at isolation and are really comfortable for me.
Also, they sound better than HD 212 Pros to me.
They're more balanced and have less boominess.
And they're easily driven without an amp.
30 bucks in stores, cheaper online.
And Grado SR-60s are probably the best dollar for dollar, but that's irrelevant here. >_>
Modded Koss the Plugs are actually really good too, here's the link to the mod:
