The HD 203 headphones from Sennheiser provide a powerful music experience in a lightweight design. The headphones feature neodymium drivers to produce clear, natural audio with a wide frequency response. The flexible headband and replaceable leatherette ear cushions provide long-lasting comfort. The ear cushions, combined with the closed-back headphone design help to block out environmental noise so you can focus on your music.
The cable provides plenty of slack and is made from oxygen-free copper to maintain a clear signal path for optimum audio quality. The standard 3.5mm mini plug and included 1/4" adapter make it easy to connect to a wide variety of consumer and professional audio devices.
