The Performance: Incoming sound was rich and full, but outgoing cellphone sound was only very slightly echoey. The effect we heard gave the listener the feeling that the caller was inside a room. Nothing dramatic, but it was noticeable. It stacked up quite well compared with our current favorite, the nXZEN nX6000, with comparable incoming and outgoing call quality. It's also just as comfortable, with both an in-canal earbud and a hook over the ear for security.
