Great Mic

The station I work at has been using Sony Lavalier Mics forever and they have sounded great. We use this mic for a weekly 30 minute roundtable discussion held in the studio. This show is for broadcast and it always sounds great. I would highly recommend this mic.

question

Is it safe to use a NiMH battery (Eneloop) in a Sony ECM-77B lavalier mic?
Asked by: David M.
It is safe. I use them all the time. However, make sure they're not more than a year old if you're using them on critical assignments. They tend to go from 100% to flat much faster as they age.
