We've recently started stocking replacement parts for the HD600 / HD650. While they have incredible build quality and reliability, they're not immune to wear and tear over the years. Aftermarket products can sometimes alter the sound of your headphones which is why it's better to buy official parts only.

Any parts we don't have in stock we should be able to obtain. Please just send us a message as we currently only stock the most in demand parts.

1. The headband minus padding.

2. The padding which makes contact with your head. This used to be a 4 cushion design but Sennheiser have replaced it with the 2 cushion design. The 2 cushion design will work fine if you previously had the 4 cushion in place; they're interchangeable. Buy here. Part no 576109 (replaced part no 549375.)
