They even found a spot on our list of the best wireless headphones. Bose typically makes great stuff. The headphones do come with a microphone, but some reviews suggest the quality is a bit off when compared to rival units. However, it still gets the job done for a quick phone call or whatever. The major downside here is the price, as $350 is a whole lot of cheddar. Luckily, today's deal calms some of that sticker shock.
