MassDrop x Sennheiser HD6XX Nickel plated CNC Copper Mass loading mod DIY kit
Drop HD6XX CNC Copper Mass loading
This is a shiny nickel plated 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 version has been designed to complement the design of the HD6xx but will work just as well in the HD600 HD650 and HD580
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.
