I've read a lot of the reviews for the M40's and the conclusion I keep on seeing is that they just aren't worth the full price tag money ($350)... but what if you could pick up a pair for $140? Would you do it? How do they rate against others at this price range? Noise cancelling isn't exactly a must have by any stretch of the imagination for me, so I'm open to other suggestions.
Just looking for more opinions.
