2. Helmet Installation
The S-9 headset can be mounted to your helmet using either the clip mount or the adhesive mount.

- Speaker Placement: Remove the helmet's inner padding. Attach the speakers to the ear pockets using the provided Velcro magic stickers. Ensure speakers are centered over your ears for optimal sound.

Route the microphone and speaker wires neatly under the helmet padding to avoid interference and discomfort.
