Tip: If the Regular size dome feels too loose, swap with the
large size. If powerful amplification is needed, swap the open
dome with the closed dome. This will enable you to raise the
volume without creating any whistling/feedback
CHOOSNG THE DOME
These domes provide a much more comfortable wearing
experience and significantly reduce or eliminate the stuffy,
plugged sensation of closed fitted ear plugs.
