Yeah, several years back I had a pair of the Sony earbuds that I bought refurbished off of eBay. A firmware update borked the battery in one of the buds and Sony was replacing them free if charge, but since mine weren’t bought new and weren’t from an actual store, they told me to screw off, so I did and haven’t been back. Before Sony ruined then they were really nice buds, but I’m not trusting them with my money anymore since they have proven a willingness to unilaterally decommission their devices.
