Thinksound USP1 (Pewter Earpiece) IEM/Earphone review.

[dalethorn]

Here's a unique earphone with pewter earpieces.  This design had me thinking (no pun intended) of Grado's porous-metal earcup housings that they use in some of their full-size headphones.  The idea here is similar - to reduce resonances in the driver housings.  U.S. made, the MSRP here is $179, but I don't know at this time what the international availability will be.
