Using headphones (HEOS 7 only)
You can listen to music through headphones by connecting your favorite headphones to the 3.5 mm headphone jack on the side of the HEOS 7 speaker. The music will stop playing through the built in speakers when you insert your headphones into the jack, and turn back on when you remove the headphones.
NOTE
To prevent hearing loss, do not raise the volume level excessively when using headphones.
