Thanks Bob. The Sennheiser look like just the ticket for me! I really dislike earbuds, and don't like the giant 'over the ear' options. The 300 are about 25 quid more than the 250, but I don't really see an advantage. Because of the need to have the big NR bit always there, I'll probably only use them when I travel. As long as I avoid Emirates, I shouldn't have to worry about cell phone interference
