The Klipsch X10i ear buds, recently revealed to Engadget during an Indiana HQ site visit, take that company's premium in-ear headphones and adds a bit of the ol' iPhone microphone and volume controls right on the cord.

The new "i" line checks in at $349, and knocks the control-less X10 down to an even $300. They won't be here in time for Christmas, or even New Year's, with their reported sell date placed ambiguously in "early 2010."

The other nugget out of Klipsch today is that the popular S4i ear buds—which reviewed favorably here at Gizmodo in August—are about the get a color refresh (as seen in the image). The price will remain $99. [Engadget]
