Peltor tactical 7's ..............also have the inexpensive 6's. Big difference, between the two. Not as good quality, as the 7's. Uses AAA penlights, rather than the 9 volt, the 7's use. One side of the 6's gave up the ghost...........started squelching. Fortunately, each side has it's own on/off switch. Only one main switch for the 7's. The 6's are a less bulky.
