Zalman first showed their compact ZM-DS4F headphones at Computex. The headphones are designed in an Apple white and can be folded together for easy transportation. Inside you will find two individual audio drives per ear cup which improves sound quality a lot. Actually, it will be hard to find a better set of headphones in the sub-$30 price range.
