How do I begin my upgrade service?

Once you have completed the checkout process, you will be emailed instructions on how to proceed. Depending on your situation, you will either be required to ship us your original headphone or purchase one from a recommended supplier.

Do you ship overseas?

Yes. Our enhancements are available to headphone enthusiasts worldwide.

What sonic improvements can I expect following modification?

Every detail of the Magnum enhancement has been designed to enhance sonic performance. However, sound quality is subjective- in this case we prefer to let our customers do the talking.

I am trying to decide which headphone to have modified - which sounds best following modification?

The magnum enhancement was designed to be seamless between both models. Whichever headphone you decide to have enhanced - both will have identical improvements in sonic performance.

Do you offer the Magnum enhancement for other headphones?

The Magnum enhancement is only available for the Grado SR325 and Alessandro MS2 headphones.

Can you upgrade my cable?

Provided you supply the desired cable with your original headphone, we can attach it during the upgrade assembly at no extra cost.

Do you sell the headband forks separately?

No. At this time we only offer a complete service.
