etymotic 4P earphones

i'll agree that you're lkely not wearing them properly. when the seal is properly maintained, i've never heard better headphones in my life. the tinny sound you describe is what happens when there is no seal.

I have the 4S's and agree with Pmotz and Lazarus28. These are the best in-ear cans out there IMO.

Have used the 4s for atleast 7years.They are great especially for airtravel and exercise.For me they only work with the white "rubber" fittings.They do clog up at times and you have to replace the green filters.They are not as good as the STAX speaker phones or the sannheiser 600 but these earphones are realy only for home use.

I have a pair of ER6's and can only say that they are the best "headphones" I've heard for listening on airplanes. As a number of people have said, the trick is to make sure they are inserted far enough and you have a proper seal. If you do, ambient noise is greatly reduced and you can actually hear music. I've tried both the Sennheiser and Bose noise cancelling headphones, both of which seem to deaden the sound.

Having said that, they are a bit inconvenient when you have to remove to talk to the flight attendant and they would not be my choice for home listening.
