Many cheaper smartphones have 2.0 USB C
Comment on Some basic info about USB

Who the hell makes a type-c port that only runs at 2.0 speeds?

Many expensive ones too. The iPhone 15 runs at USB 2.0 speeds, despite having USB-C.

And the even fucking iPhone 16!

My headphones have a USB c port and connects at USB 2 speeds.

My headphones (Sennheiser Momentum 4) have Bluetooth support. When using Bluetooth mode with the latest firmware update, they sporadically shut down while using in Bluetooth Multipoint mode.
I used headphones for decades very happily with a 1/8th inch jack.
They weren’t perfect.
-
Some devices used a 1/4 inch jack. This at least was electrically-compatible, so one just needed a cheap, appropriately-shaped piece of metal to adapt them.
-
The 1/8th inch jack connector took up enough space that the smartphone guys eventually mostly banished it from phones, to try to get a bit more space in the device.
-
There wasn’t a standard impedance. While most consumer devices used more-or-less the same impedance (and if you had to, you could just adjust the volume up or down slightly with different headphones) some higher-end headphones required a headphones amplifier that could push more power.
-
When you plugged a device in, it briefly shorted the connector, and made a lot of noise.
-
It wasn’t wireless (which could be seen as a minus or plus, depending upon whether you wanted ability to walk away from a computer).
-
It couldn’t transmit power (well, not much; there was a convention for doing so that didn’t become widespread). That became more significant with the rise of headphones with active noise cancellation, which would need at least some way to get power to the headphones.
But honestly, those were mostly pretty minor problems. Headphones just worked in virtually all cases.
I didn’t have to worry about whether-or-not my headphones supported a given sampling rate, the number of devices that could connect to my headphones, wireless interference, or physical plug compatibility aside from the 1/8th inch and 1/4 inch issue (well, and occasionally 2.5mm headset connectors on phones). USB audio didn’t resolve the calibrated volume issue. I have one set of Bluetooth headphones that start breaking up when I leave the room with the transceiver and another that work flawlessly across the house. I have charging rates to worry about, and whether the device is smart enough to have a battery management system capable of prolonging battery life by shutting off charging at appropriate points. The protocol and physical connector for telephone jacks has changed twice over the past several hundred years, once to add a ring (for stereo) and once to move from 1/4 inch to 1/8th inch. The Bluetooth and USB standards, while providing for some level of backwards compatibility, have changed like some people change socks. There are different audio protocols (and in some cases competing audio codecs, like LDAC vs aptX). Lossy compression becomes an issue with Bluetooth. Some devices don’t support some sampling rates; analog headphones don’t care. Having (effectively) zero-latency pass-through mixing is guaranteed doable with any analog headphones with the appropriate mixer, so that one can hear some other audio source live; that’s not an option with Bluetooth or USB headphones.
I do like active noise cancellation, and occasionally the wireless functionality can occasionally be handy (though in general, it isn’t a game-changer for me). But I feel like the user experience has gotten a lot more problematic, in general.

There are at least 4 different incompatible 1/8" TRRS standards.
You couldn’t have picked a worse example.

You’d be surprised. My mouse only needs 2.0, but uses a C connector for compatibility. It provides an A to C cable with only 2.0 wiring, which is a decision I assume they made to allow the wire to be more flexible as it can be charged during use or used entirely wired.

Same with my keyboard, and I appreciate the compatibility. If it doesn’t need anything faster than 2.0 speeds, there’s no reason to include more expensive parts.

It’s also important to permit use of adapters for backwards compatibility. Like, if we stop having computers with A ports, there are still gonna be some very expensive devices out there that have A ports. You aren’t going to throw out your electron microscope with a USB A port because the USB guys have decided that USB-C being reversible is cool.
computergeek125@lemmy.world 2 weeks ago
Oh totally. I have a pile of RS-232 adapters that you still need to program just about every modern Ethernet switch, and they’re all type-A ports.

Hi-speed transfer rates are just fine for devices that need to charge regularly but frequently transfer data wirelessly.

iPhone 15, Samsung A series phones and tablets, most Motorola devices, most oppo devices, most realme devices, most nothing devices, most xiaome devices, and many more

I find it hilarious that Apple did that with the iPhone 15. Gave the current technology to only the pro models 😂
They are such grimy bastards I swear, probably saved $1 just to make you pic the pro

bet they didn’t save anything and it’s the same chip just artificially limited
