Headset and Helmet Kit Extension Cable with Volume Control enables length adjustment of headset or helmet cables and volume tweaking via an inline knob. This cable allows individual volume control, thus optimizing audio experience for each person in the vehicle. Particularly beneficial for moto riders, this feature eliminates the need to fumble for concealed phones or radios. Note that the inline knob reduces the volume but doesn't augment it. To increase volume, users should boost it on their sound system before fine-tuning via the inline knob. Key features include Total Shield RF blocking and various Wired Options, specifically RUGGED for mono intercoms and STX for stereo ones. The robust, high-bend test coil cord measures 28in coiled and 6' uncoiled. This product is compatible with all Rugged, PCI Race Radios, Avcomm, RacerX, and other intercoms.
