Honestly most of these points don't make a whole lot sense, yet these are the arguments I see every time wireless ear buds pop up in any conversation.
Phones by nature are not private, and honestly, who is trying to intercept Bluetooth close to you anyways? Majority of what they would likely get is "oh another person listening to music or tiktok".
I haven't charged my 3 year old $50 Bluetooth buds in weeks, and they are still sitting at great battery health. Proper research and care goes a long way, though the option to have replacement batteries is def a plus. And if you're going on long road trips, just pack an adapter and wired headphones if you're that conscious.
What are you doing with your phone that you need top-tier audio quality on the go? Just seems like a very very niche market.
