Frequency Boost Ear Plugs

Block the noise. Feel the frequency.

Frequency Plugs are reusable earplugs built to wear with your High Frequency Highway headphones. Put them in, put the headphones on, and two things happen at once: the room goes quiet, and the frequency gets louder.

Use your headphones anywhere. The train. The office. Seat 22B. Your bed with a snoring partner next to you. Any room becomes your room. Pick Focus, Calm, Energy or Sleep in the app and the outside world stays outside.

The frequency feels stronger. Blocking your ears makes the frequency louder and clearer, because nothing from the room is competing with it. Try it right now: press your fingertips into your ears mid-session. That jump is what the plugs give you for the whole session, hands free.
