The battery from the 510mah to the 850mAh. I got a little bit more of listening time with the upgrade. I did have to do some soildering. I was pretty close to donating them last week.
I was having issues with my Ora Grapheneq headphones and they weren’t powering on. I short circuited the battery along with a Bluetooth speaker I had when I connected them both to charge on the same block. Big mistake. I decided after a few years to open it up and replace
@thejefflutz@YouTube I decided to cancel it. I’m not paying that much for something I don’t use everyday. They need to cut the % they take from content creators if they are so concerned. Good way to pass their problems on to paying customers.
