My faithful, folding Sennheiser PXC300s are still going strong, despite many airmiles! (And Grado SR125s at home). In-ear headphones typicially make me feel claustrophobic after a while, though I am planning to try out some of the newer, less-scary designs (eg the Klipsch X10s; Sennheiser IEs etc).
