I’ve seen the feedback on how bad they were (are), but my experience was and is just the opposite. I’ve had batteries last a very long time (years - yes, seriously, years on a set of batts. Current set is four years old and still ticking) and give me all the power I need for a day’s wearing (~14 hours). Maybe I got the magic pair. I don’t know.
I did have the doors replaced and the charger firmware updated years ago on my original OPN 1s and have now purchased a backup set of OPN 1s off Ebay along with the charger, and want to make sure the charger has that firmware update if I can find it. RIght now I’m just using my old charger that I know has the updated firmware.
