etymotic 4P earphones

I own the E4S and mine sound tinny too. I use them with a Headroon Cosmic reference amp and I am not happy with either products. The ear plugs must be pushed deep into the ear and feel irritating. If the seal is broken there is no bass and the sound becomes tinny. So push the plug well into the ear and wet the rubber plug for a better seal. And do not move around too much or the seal breaks. As for the Cosmic, I though it would sound better than what it does for the price. $800+ dollars! Also the CDs played through my CD player are bright sounding to begin with.

I've got the 4P's and I wouldn't consider them tinny at all. While the bass is not as good as my home system the rest of the spectrum is very good. The problem could be the drivers are not sealing properly. Either the fit is off or the driver is not being placed deep enough in the ear. There could also be a problem with whatever you are using to drive them. The Etymotic's are not for everyone and that probably is the case for you.

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.
