Currently, the lowest priced Shure earphones here in the States are the SE110 at a modest $119, but that might change. Shure is releasing the E2c plugs over in Japan for 8000 yen, working out to be an even more modest $75 USD. I’m not a Shure aficionado but I do understand retail price points, and having a Shure-branded unit to compete with high-end Sony and JVC models does have a nice ring to it. As for the specs, the earphones play at 22 Hz to 17.5kHz with an impedance at 12 Ω.
