This is a modern headphones, however, it has some classic looking elements. The checkered band is more classic, but the logo is modern. The background used on the outside of the headphone is the modern 'swirl', and the slightly raised Sonic face (rubbery plastic) looks classic, but isn't. (See green eye detail) They've slightly modernized the 'classic foreward facing Sonic' stock art for use here. There is a volume control on the cord for ease of use (seen at right with Sega copyright on the back) The cord is nice and long, and the sound quality is good. These should be about $19.99 at Toys R Us in 2011 / fall. 
CAUTION- These can break fairly easily. Either some have a defect or the band is not quality. It can snap in the middle after only a few uses. Beware if you buy these to use, and be extra careful. Fact by Ink the Echidna.
