I recently got turned on to the amazing difference between good quality headphones and the trash that usually comes standard with most portable audio devices. My entry into the world of better-than-garbage headphones came in the form of the relatively inexpensive Grado SR-60s, which have served me well.
Now, I've moved and am lucky enough to be enjoying commuting hell every day on the commuter rail into Boston. The Grado's are nice with my iPod in a quiet environment, but they do nothing to block out the ambient noise on the train (conversations, cell phones, train noise). So, I'm looking into some noise cancelling options. My two front runners are:
Etymotic Research ER-4 MicroPro Earphones ($249.99) http://www.etymotic.com/ephp/er4.asp
These don't offer active noise cancelling, but due to the in ear design, they are supposed to be excellent at the task.
Bose Quiet Comfort 2 Noice Cancelling Headphones ($299.99 - $100 discount) http://www.crutchfieldadvisor.com/ISEO-rgbtcspd/reviews/20030715/bose_review.html
These do actually include active noise cancelling circuitry.
I'm going to check out the Bose headphones this weekend, but I wanted to see if anyone had any thoughts, opinions or experiences with either one before I venture out. Thanks for the help!
