My old ones broke two days ago and I needed new ones. I chose earbuds from NOTHIHG because according to reviews they are really good for the money. Now, their app is asking me to accept this privacy policy. Maybe this policy is just some general place holder for other products because they sell phones too. And they would have browser history there. Or I could use the earbuds without the app. But the default tuning on them is very bass heavy and I need to change that.
I use DNS resolver on my phone with a lot of filters, so this shit will get blocked. I think I will bite the bullet for now but this is probably the last thing I bought from this company.
No. A bluetooth headset (or any wireless audio thing really) has to contain a bluetooth radio, a digital-analog converter, and an amplifier. The signal goes through all of that before it reaches the speaker. The aux input bypasses all of that and goes directly to the speakers, using whatever DAC is on the other end of the cable. It's purely an analog signal connection and can't power the electronics. It also means that when the battery inevitably goes cack, you can still use it with a wire.
Some expensive headphones, like the Focal Bathys, offer USB-C input, which essentially turns them into external sound cards. Excellent video, watch the entire thing.
