Description

A modified pair of Beyerdynamic DT990s.

 

We add mass loading and dampening to this pair along with a foam disk to tune the sound.

The mass loading consists of a copper ring added to the back of the driver. This gives the driver more weight to push against, reducing unwanted flex and distortion. This also reduces the resonance of the driver for a clearer, more accurate low end.

 

The dampening is used on most surfaces inside the headphones. This reduces reflections within the headphone.

We remove the white internal plate from the headphones. This is a solid plastic disk and makes the headphones almost closed back with just two small openings.

 

We replace this with a foam disk that allows the driver to breathe and makes the headphones fully open back. The foam tunes this to give a more pleasant, neutral tone.

 

Together these mods achieve a more detailed and accurate sound with better soundstage and a tighter low end.

 

Frequency Response:

Purple = Stock

Orange = Modified

 

Please note that this pair does not include our detachable socket mod and the stock cable will be left as is. If you would like a detachable cable see the listing here in balanced and unbalanced flavours:
