Mine weren?t, anyway. -I thought the slightly bigger size compared to the G305 wouldnt be a big deal and it kinda isnt but its still a bit of a problem since it restricts me with vertical movement and horizontal movement to a lesser degree. If you need more memory this is in the specs - different type of cards for different amount of memory: microSD card slot accepts, microSD, microSDHC, or microSDXC cards (available separately)The Sony Music Centre software is serviceable and works. This looks a whole lot better. As a pair of headphones this wouldve gotten 5 stars. I?m now obsessed with this brand. I normally wear a size 7 -7 1/2-I ordered a 7 & these are at least an 8 1/2! These fit as expected, are comfortable for daily wear or for the gym. ? 2-year Limited Bose Warranty is included. Had to return these.
