Just got a pair of the Peltor Worktunes and they are great, that is for sure! Only complaint I have about them is the darn on/off switch which doubles as a am/fm selector.... press the button once and you switch bands, press and hold it and it turns the radio off.. I think so far I've gon thru 4 or 6 AA batteries all because when I thought the unit was off, it wasn't. It was on am mode, just tuned to a dead-air station (the equivalent of 104.3 on FM) so I couldn't tell they were still on. Now at the end of the day, I pop the batteries out completly. A little pain, but works fine. Anyone else do the same?
