How exactly are you going to have a new FC soon? If you discovered a method to change it, I'd love to hear it. Hate the fact that my FC starts with "0920" (Hate zeros as the first or last number of the initial part of the FC)
I used to have my entire music collection in FLAC, but there is so many songs and devices that I want to store them that lossless compression wasn't enough, not to mention compatibility
a few years ago I decided to convert everything to mp3 with a relatively high bitrate, I had a terrible feeling I would regret doing that but to honest, I couldn't tell the difference in the audio quality after I did that
I used to use high end headphones and speakers JBL back when they made good speakers lol X-Fi Fatality edition sound card on PCI with XP back when Windows had good sound....
I got the Google Pixel Pro buds, they're good enough for when I need portable audio. And some really cheap IEMs that Dankpods recommends, I think the KZ ZSN Pro
I'd stick with cheapo Chinese $10 ones quality is actually becoming on pair with name brand since name Brand usually quads the price up anyway loose one bud that's another $200
My Pixel Pro buds shit the bed a month or two ago. My wireless charger (which they do support Qi charging) absolutely COOKED them. Caused some problem that caused the case to heat up to 180F+
They were like 9 months out of warranty but I hit up Google support anyway and told them how hot they were getting and they replaced them with new ones because they wanted these for failure analysis lol
Anyways, you can do change the FC without formatting with GodMode9.
