The Jaybird X4 lists for $130 and is shipping now.

Jaybird

Jaybird, one of the early leaders in wireless in-ear sport headphones, has a new X-series headphone, the X4. Not only is it sweat proof but Jaybird says it's fully waterproof, with up to 8 hours of battery life and fast charge feature that gives you one hour of play time from a 10-minute charge.

With this type of headphone it's important to get a tight seal to maximize sound quality and not lose any bass, and to that end, Jaybird has included new tips and fins that promise a more comfortable, secure fit. Beyond the silicone tips, they also come new "exclusive-to-Jaybird" Comply Ultra foam tips for those that like foam tips.

Thankfully Jaybird has a new cord-management system -- it's called Speed Cinch -- that makes it easy to adjust the cord length. You can leave the cord dangling down or wrap it around the top of your ear for an even more secure fit.

I should have review sample of these soon and will give you my hands-on impressions of them after going for a few runs. My gut reaction is that with so much competition in the sports headphone market, $130 is a little too expensive for the X4. I suspect you'll see it on sale for less than $100 during the holiday season.
