Sennheiser Firmware Update (Smart Control App)
The failure mode is statistically a software-induced state-lock where the HID (Human Interface Device) profile stops communicating with the capacitive touch IC. Updating to the latest firmware version optimizes the polling frequency and resolves logic loops that cause the touch sensor to become unresponsive during active Bluetooth streaming. This is the primary corrective action recommended by the manufacturer to re-initialize the I2C bus communication.

Right Ear Cup Assembly
If firmware re-initialization fails, the root cause is typically a hardware failure of the capacitive sensor grid or the digitizer PCB located behind the outer shell of the right ear cup. Environmental factors such as moisture ingress or ESD can degrade the conductive traces on the flexible printed circuit (FPC), necessitating a replacement of the entire right-side acoustic/electronic housing assembly.
