The shorter body is perhaps less awkward to C700's larger potruding body. Built with elastomer cord and gold-plated stereo mini-plug. Ear canal buds fits snugly. Stays in place even during vigorous exercise, eg. jogging, treadmill. Blocks out external noises, creating an excellent inner ear acoustic environment.
