Ends tomorrow. Newegg has the Philips SHB3075BK BASS+ Wireless Bluetooth On-The-Ear Headphones with Mic (Black) on sale for $18 with free shipping. Features 32mm drivers, fold flat design and up to 12 hours of use per charge. 

I own a couple pairs of these, I think for the price the sound quality is really nice and they're pretty comfortable.
