Newegg offers the Philips Bluetooth On-Ear Headphones, model no. SHB 4100, for $19.99 plus 99 cents for shipping. That's tied with last week's mention as the lowest total price we've seen. (It's a current low by $14.) They feature 32mm drivers, Bluetooth 3.0, leatherette ear cushions, and a USB charging cable. Deal ends September 23.
