Audio-Technica ATH-OX7AMP on-ears for $80 (with built-in amp)

Audio Technica’s experimentation with a built-in amplifier (powered by one AAA) into a SonicFuel consumer headphone is on the discounting path, you can get the new condition Audio-Technica ATH-OX7AMP on-ears for $80 with free shipping by BuyDig’s ebay store (authorized dealers, limit 5), and for $90 through amazon.com. The headphones work without battery (but obviously not the amplifier). They come with two cables (detachable) and a bag. Picture #2 in the amazon.com gallery is a close-up of the earcup connections (power, volume, audio-in).
