Newegg offers the Philips Bluetooth Over-Ear Headphones in Red, model no. SHB9100, for $39.99 with free shipping. That's $5 under our mention from two weeks ago and the lowest total price we've seen. (It's a current low by $12.) They feature a frequency response of 18Hz to 21kHz, soft sound-isolating cushions, smart controls (for switching between calls and music), and 3.5mm plug-in option.
