It's amazing how bad smartphones are at being telephones. The old black Property of Ma Bell telephones had better sound quality, at least they cradled your ear and captured your voice. As an old fart I can attest to it.
It's a fundamental limitation of the technology. Anything wireless, when it comes to audio, requires a certain amount of fidelity loss in order maintain real-time transmission without using an astronomical amount of bandwidth. With landline telephones, you have an exclusive, end-to-end physical connection, so you're free to fully saturate the line with as much information as it can carry. It's possible to fit multiple analog audio transmissions onto a single copper line, but the signals need a hard frequency cutoff for it to work. This is why long distance and international calls used to sound worse than local ones. In a similar vein, terrestrial radio has to split airspace between multiple stations, which is why it sounds worse than records or reel-to-reel tape, despite each station using a massive amount of bandwidth by modern standards.
Moving into the digital realm, the same principles still apply, but you can push bandwidth requirements way down thanks to the inherent efficiency of digital encoding, plus the magic of digital compression algorithms and error correction. As a result, wireless digital audio transmissions can maintain a much higher level of fidelity than analog ones, compare Bluetooth audio to FM, for example. Quality still needs to be sacrificed somewhere when transmitting wirelessly though, which is why audiophiles bitch about Bluetooth headphones and wireless mics. Even the best digital audio compression can't compare to a copper cable carrying an unfiltered analog signal.
Digital audio compression is what makes it even remotely possible to have hundreds of real-time audio streams transmitting wirelessly to a cell tower, unfortunately you have to reduce the audio quality down to the absolute limits of usability in order to pull it off. Even if you still have a copper land line, the audio is always going to sound like crap if you talk to someone on a cellphone, it's just not possible to operate a large cell network with the same level of fidelity.
As a fellow old, can confirm. Old analog landline was actually listenable.
