There's a tradeoff with wired headphones. Sometimes they act like their own antenna, and if you live in an area with very poor reception, then that becomes a huge problem. In that scenario, bluetooth earbuds are actually preferable, until they run out of battery mid-call.
- BenjiWiebe 4y agoNot saying this is impossible, but it doesn't make sense to me. The phone antenna isn't a straight piece of wire entwined with your cable (probably not even parallel with it), and your cable isn't connected to the antenna port. How would the cable block the signal?
- cyral 4y agoMaybe they mean the noise you can hear from the phone as it communicates. I wonder if it is more pronounced when reception is bad as it searches for other towers? I had wired headphones + mic with an amplifier for a while and if I put my phone anywhere near it you'd hear the classic GSM buzz.

You might find sometimes even stereo sound speakers pick up a ticking noise right when you receive a phone call. This is pretty common with speaker systems, wired headphones being a type of speaker system. Also, a lot of SoCs with FM antennas use the 3.5mm ground as the antenna, so they are wired into the SoC in such a way that they can receive undesired interference.
