For flying, the Etymotics ER-4s is the best I've heard. Isolation is almost complete. I've got to take an earpiece out to hear the flight attendant talking in my ear, and sound is great. These are not the most efficient IEM, but the ER-4P version is an easier load for a player, and provides the same isolation. Some people have comfort issues with Etymotics, but I do not.
Sonically, the Ultimate Ears UE-10 Pro has the best sonics I've heard in any IEM, and is better than most full-size headphones. The UE-10 has to be custom fitted to your ear with a mold taken by an audiologist, and is a good deal more expensive than the Etymotics. Despite the custom fit, I get less isolation than I do with the Etymotics. My reference headphones are the Sony R10 and Sennheiser Orpheus. -- hirsch ------------------------------------------------------------------------ hirsch's Profile: http://forums.slimdevices.com/member.php?userid=7288 View this thread: http://forums.slimdevices.com/showthread.php?t=33748 _______________________________________________ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
