"Cancels out most noises, and are good NC headphones"3.5 starson by shopper911
Pros: comfortable enough for long trips, great sound, build quality of Sony is always great, stylish
Cons: does not block out everything. That is all I can think of.
Summary: I just recently bought these for a future trip. These headphones block out the airplane engine noise, my three fan laptop which sounds like a rocket about to launch, and basically any thing that would be considered ambient noise is blocked. And No kids whining is not ambient noise!
