Sorry if this sounds like a stupid question, but i just wanted to see if it was me who has experienced this. I was listening to my Ipod touch (32gb, 3rd Gen) earlier today while i was out, through a new pair of Shure SE115's and the sound quality was great. However once i got home i plugged in the same pair of headphones into my Macbook, and noticed that the quality was not as good. Dont get me wrong, the quality when plugged into my macbook is by no means bad, but there is a definite difference compared to my Ipod. Anybody have any idea why this may be?
