Focus Camera offers the refurbished Audio-Technica ATH-ADG1 Open-Air Gaming Headset
with free shipping
. That's $29 below last week's mention of a refurb and $110 under the lowest total price we could find for a new pair. They feature 53mm drivers, Bobbin-wound voice coils, a microphone with 100° of motion, detachable USB digital-to-analog converter with built-in headphone amplifier, and 5Hz to 30kHz frequency response.
A 1-year warranty is provided, but it is unclear who backs it.
