    The headphone wire also serves as a FM radio antenna. You can’t get that with wireless headphones or a connection via the USB jack.

      I haven’t listened to FM radio in probably 8-9 years. It’s literally nothing but ads with a few minutes of the most commercial music shoved down your throat 12 times a day

          On AM stations yeah. Not FM though.

          AM is a while different beast, and there aren’t any phones with AM receivers.

            AM is literally on its last legs in the UK, even BBC Radio 4 shut down on it recently. Soon it’ll be just Radio Caroline and the odd hobby pirate.

            We’ll come to regret it I think, the old Radio 4 signal could be picked up all over the country from like three transmitters and received on something as basic as a razor blade and coil of wire. We’re so keen to turn the internet into a massive single point of failure, and it’ll bite us in the arse with the Russians going about cutting our cables.

                ‘Blocked in your country’ unfortunately but get what you’re on about. The loss of Test Match Special on 198 kHz was actually a mild cultural loss in my opinion, cricket is supposed to arrive on a crackly amplitude-modulated carrier.

                Europe has (soon to be had) two AM broadcast bands; medium wave which is more or less the same as North America but it’s shorter and has 9 kHz channels, and long wave which goes down really low from 153 to 279 kHz. Long wave is properly antiquated tech, you need genuinely enormous aerials to efficiently put it out but it covers ludicrous distance over ground wave. It used to be used for broadcasting the UK’s main radio programme to ships and remote areas, and could get a thousand miles or so out to sea with just one transmitter.

                  I’m sorry it’s blocked for you. But while I have never listened to a Cricket Match, I would bet the farm it’s tailor made for radio like baseball.

        I agree that most radio stations are shite. Fortunately, I live in Ireland, which still has publicly funded broadcasters. I have my phone permanently tuned to Lyric FM, which plays classical music with almost no commercials.

        I think they’re joking about earbud wires catching AM radio signals and giving spooky whispers

          I don’t think they’re joking at all… what they said is true. If the phone has an FM receiver then the wired headphones do serve as the antenna for it. It will not work without wired headphones.

          Back in the day that was a good way to have free music over the air if you didn’t have an unlimited data plan, which most people didn’t.

          It’s just obsolete tech now. Having a headphone jack doesn’t mean anything if the phone doesn’t have an FM receiver. Most phones don’t have an FM chip in them anymore.

            It means I can connect my phone to my car stereo without a bunch of fucking dongles.

            My current phone is Samsung XCover 4. It’s a fairly newish rugged phone; still has a FM receiver.

              No you can’t… at least not easily or cost effectively.

              It’s not just the wire on the headphones, it’s how an analog jack works. A 3.5mm audio jack routes raw analog signal through a direct electrical connection. USB doesn’t not. Without the raw analog signal, the FM receiver can’t do anything with it.

              You need extra hardware like an analog pass through to get USB to handle analog radio signals. And that’s expensive and bulky for no benefit over an audio jack which is compact and dirt cheap.

              Respectfully, you don’t know what you’re talking about here.

                I’m not disagreeing that the FM radio circuit being directly connected to the trs connector is how phones worked for decades, I’m just saying that they said you couldn’t get FM radio over usb, so I assumed they must not be talking about literally receiving FM radio to the computer because obviously you can use SDR over usb. Maybe I’m just too autistic to appreciate what they were trying to say, but the interpretation I had from their comment was that killing TRS removed the ability for your phone to receive radio even including over usb, which is demonstrably wrong. But yes, your phone receiving the raw analogue signal through the TRS connector and using its dedicated radio circuit is in fact a thing, and almost certainly the better way to do it.

          My Motorola has an FM receiver app. You can scan and save your favorite stations and save them separately for different cities. You can even record audio. I’ve used it in places where reception sucks for streaming from my home server. And if you don’t want to use the headphones, you can switch to speaker or BT and still use the wire as an antenna.
