I have a few cheap sets of headphones. None sound great, and all of them are falling apart, so it's time for me to splurge a little and get some decent ones so that I can once again enjoy my music, mostly classical and hard rock. So guys and audiophiles, in your opinion, which are the best sounding ones for under $100, the Grado SR60i? Are the SR80i's worth the extra $20 that most sites charge for them? And lastly, from what I've read, none of the in-ear headphones sound as good as the larger designs, but in some circumstances are a lot more convenient. Which in-ear headphones are comparable to the Grados mentioned above? Thanks in advance for your expert advice and help.
