B&H Photo Video offers the HiFiMan Edition S White Lightning Open/Closed-Back Headphones for $149 with free shipping. (HiFiMan charges the same.) That's tied with our November mention, $100 off, and the lowest price we've seen. Features include 50mm dynamic drivers, asymmetrical ear cups, an Android/iOS in-line cable, 18-ohm impedance, and 15Hz to 22kHz frequency response.
