I am looking for a new set of cans to use. Currently I have Sennheiser HD25-1 II and Beyerdynamic DT770 80ohm version. Only problem is I use these at work only, they both sound great to me at least, but I usually do not take them on the road unless I use them for work purposes. I mostly listen to headphones on the go, working on the house/yard. I have been tempted to save up for Sennheiser HD600s but for the money I could probably find a couple other things currently that my money is more well spent on. The only other things that I have looked at seriously is the Grado line-up. The SR80s seem very affordable and have great reviews, but I am willing the spend the money on the 325s if they are really worth it. Can I mod the 80's to get close or should I buy something in between? My musical tastes is semi wide. I mostly listen to metal/rock/indie every now and then I listen to jazz or classic rock. Any help would be appreciated. Thank you in advance!
