Groupon offers the Polk Audio Hinge On-Ear Headphones in Black, model no. AM4119-A, or Brown, model no. AM4118-A, for $29.99 plus $3.99 for shipping. That's tied with last week's mention as the lowest total price we've seen. (Outside of the price below, it's the best deal we could find for these headphones today by $96.) Features include pivoting ear cups, in-line 3-button control, and detachable single cable. Deal ends May 27.

A close price: Sonic Electronix via eBay offers them in black for $35 with free shipping.
