Custom Cans are proud to announce a new range of Aluminium Sennheiser HD25s. We have had the earcups and hinges machined from a solid piece of billet aluminium and then anodized in a range of colours. We have updated the design of the parts slightly to make them more rounded to make them look and feel a little nicer.

We’ve also got a selection of pads to choose from that can be fitted free of charge if you make the purchase along with the headphones.

The headphones come with the standard stock steel cable wrapped in your colour of choice, measuring 1.5m in length and terminating in a threaded angled 3.5mm jack, bundled with a 3.5mm to 6.35mm screw-on adapter.
What does mass loading & damping mean?
We attach weights in strategic places on the driver to give it more mass to push against – this gives a little more bass extension, and cleans up the mid bass. This helps make them sound less boomy and gives more bass detail. We also change the damping material in the cup to absorb more sound inside the cup, so less bounces back through the driver. this also helps with clarity and makes them sound a little more open / less boxy.

About us

We have been modifying and customising headphones for DJs and other audio professionals for many years (starting back in 2009), during which we have gone on to win several awards. We are official Sennheiser and Beyerdynamic partners, so we always have the latest version of the HD25 and spare parts in stock. All of our custom headphones are airbrushed and painted by hand. We spend a great deal of time making sure each pair gets a finish that will last in a professional environment for years, which is no small feat.
