As one of its daily deals, Amazon offers the Sennheiser Momentum On-Ear Headphones in Green for $70 with free shipping. That's tied with our expired mention of a different color from four days ago and the lowest total price we've seen. (It's also a current price low by $9.) Features include a 110db sensitivity, 16Hz to 22kHz frequency response, 18-ohm impedance, iPhone-compatible cable with remote, microphone, and carrying case. Deal ends today.
