Rugged Challenger II Foam Mono Earbud

The Challenger II is a single-ear foam earbud speaker built for two-way radio communication in racing and marine environments. It connects directly to a 3.5 mm mono jack and uses rugged blue cabling manufactured in the USA for durability in harsh conditions.

Installation and common issues

Plug the 3.5 mm mono connector into the radio's earbud jack and insert the foam tip into one ear for immediate use. The fixed 21" cable length limits routing options in larger cockpits, and the mono plug will not carry stereo signals if the source expects a TRS connection.

3.5 mm mono plug compatibility

This earbud requires a 3.5 mm mono audio jack wired for single-channel output. Radios or intercoms with stereo-only or balanced microphone jacks will not work correctly, so verify the jack type before purchase.
