The Mushroom Hollow Foam

September 1, 2024

The Radius Mushroom Hollow foams have been carefully designed for small condenser, short pencil mics and the MKH 50 - for users who particularly use the RAD Shockmounts. With the 'mushroom-like-shape', it eliminates the risk of the foam coming in contact with the RAD Shockmounts hoops. Preventing any risk of handling noise.

Each foam has a layer of non-slip silicone to prevent the foam from slipping off whilst recording. This comes in handy particularly when using additional Fur windcovers.

Inside the hollow foam you will find a ø40mm cavity. The cavity has been carefully designed to allow for 'dead air space' around the capsule, giving great isolation and clear sound quality.

Each foam can be found with or without the fur windcover too - giving you that little bit extra wind protection when needed.

All our foams are made in the United Kingdom using a semi-open cell material that is also resistant to UV and moisture.

Why is there a cavity?

The cavity has been designed to allow 'dead air space' around the microphone. This ultimately gives better isolation and also clearer sound quality.

Each Mushroom foam has a ø40mm cavity.

Which size is best for my microphone?

We offer the Mushroom in 2 different sizes.

5cm Mushroom Foam 19/22 &

5cm MKH50 Mushroom Foam 24/25

If you have a small condenser or short pencil microphone like the Schoeps CMC6 41 or DPA 4018C, we would reccomend the 5cm 19/22.

The Large hole 5cm Mushroom is a perfect fit for those who have the Sennheiser MKH50.
