It's hard not to love the concept of bone-conduction headsets: government-funded technology (much like the iPod), fairly positive reviews on sound quality in noisy environments, and most importantly, they represent the closest most of us will ever get to bionic implants. The tech is still fairly young, though, and previous entries from Nextlink and Aliph have come up short in the size and, uh, wire departments. Nextlink's at it again with their latest entry, the Invisio Q7, and both issues appear to be solved. The Q7 takes the shape of Nextlink's well-liked Bluespoon line, adding Bluetooth and a send/end button for good measure. At $200, the headset is a bit steep when it looks to drop toward the end of the year, but if it means we can hold a phone convo in the middle of a raucus Engadget reader meetup, we're all for it.
