an Ear canal Microphone (ECM), where the ECM is part of the earphone, wherein the ECM generates an ECM signal;
a speaker, where the speaker is configured to play audio;
a user interface;
a pumping mechanism;
a sealing section, wherein the sealing section is configured to reduce radio frequency (RF) transmission past the sealing section when compared to a sealing section composed of silicone, wherein the sealing section includes a variable volume elastic membrane;
a memory configured to store instructions; and
a control circuit that is configured to execute the instructions to perform operations, the operations comprising:
receiving a command from the user interface to activate the pumping mechanism to move fluid medium containing particles into a volume encapsulated by the elastic membrane, wherein the particles are RF absorbing;
receiving a pressure value inside the volume; and
sending a signal to stop pumping when the pressure value reaches a threshold.
