I've got two killer in-ear headphone deals for your to agonize over today. Up first is Sears' offering of the Yamaha YER-500BL for just $24.97 as a daily deal. It's the lowest price we've seen. While Amazon reviews are sparse, they average 4.5 stars. Next is the Logitech Ultimate Ears 500 Noise-Isolating Earphones at Amazon for $22.95, their lowest historical price.
