HD600 / HD650 CNC Copper Mass loading mod DIY kit Black edition
HD600 CNC Copper Mass loading
This is a copper weight which adds mass to the rear of the driver and smooths the airflow slightly. By it’s self it gives more detailed bass and a little bit more sub bass. Ideally it should be combined with the removal of the foam disk on the rear of the driver which will further improve the resolution of these, already, great headphones. This is the same as the standard version but now painted black for a more stealthy look
The mod can be fitted with no special tools and can easily be removed in the future.
We have now also updated the kit to include 4 different foam inserts that allow you to tune the bass levels to your own personal taste whilst keeping the extra bass clarity and detail you get from adding the mass loading weight.
