I lost my beloved etymotic 4s on the plane. Maybe I should buy them again. These sealed isolation things are great but in buying $40-150 ones I’ve found the biggest variable is a good seal: 1. Brookstone Pro Plug. $40 so inexpensive. Fit is not really sealed bit they r just so bassy. Not recommended….
My friend Akemi is working at Open Interface, with the new stereo bluetooth coming out, you can get just amazing headsets.
