It is well know that Neil Young likes horn loaded speakers and is a Klipsch owner, but I didn't realize he also loved Klipsch R6 ear buds.
"Neil Young was interviewed on episode #199 of the TWIT network's Triangulation program about his Pono Music Player, the super high fidelity audio player that plays back up to 192 kHz / 24 bit, and when asked what kind of headphones he uses said that when he is on the go he prefers Klipsch R6 in-ears. He thinks they are the best, fit well, and have a good balance between bass and treble. Paul Klipsch started making loudspeakers in 1946. Thecompany, located today in Indianapolis, began making in-ear headphones and headsets in 2007."
