In most airlines the announcements are at fixed volume, independent of the movies. That means you can put the video on full volume and turn it down inline. No more announcements screaming in your ear :) (and better sound quality as a bonus)
Yes, I too travel with both of these. The volume control is convenient, but I originally bought it after breaking a couple of my headphone connectors. Now I break a $5 part instead of a $50 part. (Shure's with removeable cords are great, but the cord is still $50)
Both your link, and the link above, are two components I recently purchased after my own experiences. Just funny to realise I wasn't the only one who encountered this...
