Phones should have FM radio again
Phones should have FM radio again
Headphone jacks are the last analog component in smartphones that still have them, and make it harder to waterproof the devices.
Want to listen to the radio? Get radio.garden or another app and you can listen to any radio anywhere
Digital headphones have better sound quality than analog headphones, too.
But what’s the problem with having an analog component?
Also, your last claim is weird, because the headphones will ultimately require an analog signal, so, it just changes the place where the conversion is made, either in the user device, or in a digital circuit inside the headphones, and the cable diatance is small enough for adding interference. Your better sound experience is probably due to manufacturers making better sound actuators, not due to the digital data transmission. Try some really cheap bt headphones, and you will see what bad quality is.
Indeed, interference is the greatest enemy of analog signals. It’s not impossible to shield, though. Other parts are already shielded, but I can see how it could have become more challenging.
Btw, I thought it was more related to frequency than components size, but now I’m confused, I will look more into it when I have more time. Thanks for bringing this into the topic.
