Sennheiser Replacement Connection Cable
The male pins on the 2-pin connector are subject to friction wear and oxidation over time, reducing their effective diameter. A new cable provides fresh contact surfaces with the correct tolerances to interface with the internal driver springs. This is the primary non-invasive fix for mechanical looseness.

HD 660S Driver Capsule / Transducer
The female connector socket is built directly into the transducer housing. If the internal leaf springs have been over-extended or deformed by improper insertion, the clamping force required for a secure fit cannot be restored without replacing the entire driver assembly. This is the final resolution for housing-side mechanical failure.

Contact Deoxidizer Solution
Micro-arcing and environmental oxidation at the contact points can create a layer of resistance that mimics a loose connection through signal dropout. Chemical cleaning of the internal spring contacts can sometimes improve the electrical 'grip' even when mechanical tension is slightly compromised.
