Neo Geo Pocket Stereo Headphones were released in Japan in 1998. As shown in the image, they are the earbud style that is inserted into the ear, rather than being held by a band, or similar. Sound quality is good (better than one would expect from a pair of headphones costing only $10), and they are well made in general. There is nothing to distinguish them as a product of SNK, though they are well suited to the Neo Geo Pocket, since the cord is rather short.
