Sound is OK but I can't compare it...seems like the low end is missing a bit. I like there is no speaker holes though.
I love the sound from my 15" Macbook Pro. The 2 things that sold me this laptop was the screen quality and sound. At the time I would have bought the 13" but the screen quality and sound quality put me off from buying it. This 15" that I have is just too big to carry around with me and take along on flights so I am back at looking at 13" Macbook Pros now.
Hard to imagine how a $1000+ laptop these days which has Itunes on it for listening to music and watching movies comes with worse speakers then some cheap China made mobile phones I use Skype often and there is nothing worse then a pair of bad speakers on a laptop computer.
