1. I have aux earphones and it needs to work with some extension on new phones.
2. Earphone while charging
3. Enabling OTG for usb eaphone

I haven't seen a single phone that has more than one USB-C port, and I would like to listen to stuff while these these phones charge their miniscule batteries.

I would need to replace my headphones, too. Right now I'm able to plug in my studio monitors, my earphones for biking, my wife's earphones, my kid's, my spares, ... I can buy cheap replacements, or repair then easily. Kid kept breaking his so I started repairing them, which turned out to be almost trivial. Mostly wires getting loose in the cups or the plug itself.

1. I want to be able to charge my phone while using headphones
2. My laptop doesn't have USB-C

I do it out of principle. I disagreed with their decicion to remove it like so many others at the time but unlike the vast majority of those others I decided to vote with my wallet and to this day I refuse to buy a phone without one.

While I do use a USB-C phone, the thing I miss most about the audio jack is a wired audio connection that doesn't remove charging or require a separately purchased dongle.

I hate dongles with a passion. They're so easy to lose. And for what? So your headphones work like normal? Not worth it.

i don't even use headphones, however I don't like buying new things that have less features then my old things, so I keep buying phones that have both sd slot and a 3.5mm jack...
however i had to give up 2 sims + sd in my latest phone... Combined slots are such a stupid idea (1 sim + sd/2 sims)

1. Decent audio for cheap.
2. beeing the aux chad on parties for moments when the system requires it.
3. ???

Nobody wants to buy and carry around crappy dongles which get lost. Plus the usb c sound of not any better, in some cases it's worse, especially on a cheap dongle. So now I'm expected to buy expensive dongles to be sure they work, on top of the price of the phone, as well as a phone charger because they don't include that either, when the 3.5mm jack gives me 100% quality audio experience?

No thanks. I'll keep buying phones with headphone jacks.

3 times a week I go for dialysis and I can either take Bluetooth headphones or wired. I tried the Bluetooth to see what it was like and its just clunky. It's bulky and akward to use one handed plus once the Bluetooth in ear bud fell on the floor. I can't get up at all during the session so it had to stay there until I was finished

Whereas I now take my cheap(€10) Sony wired in ear headphones and they are far smaller in my pocket, easy to use, the bud didn't fall out of my ear because it's smaller (no circuitry and battery) and when if it fell out it wouldn't fall on the floor because it's attached to a wire. Plus I'm not isn't extra battery power on my phone while listening whereas Bluetooth will drain my phone battery.

I can't connect to my car's audio with Bluetooth, and can't afford to replace the car stereo with one that supports Bluetooth - it's just not a priority. When I upgrade my phone, I'll stay with an earphone jack.

Another reason I discovered recently. I work at home on a company laptop. Can't do shit with it so I listen to music via my phone or personal desktop. I tried using Bluetooth gear but realised quickly that if someone called me on teams/Skype or whatever, switching device with Bluetooth is tedious and slow. Wired stuff goes out and in, boom. Oh and none of my computer's have a usb c port despite one being fairly new (2021).

My laptop has exactly one USB-C port. It's on the back and it's the one port that directly connects to the GPU so slightly better performance if I use that with my external monitor. The audio jack on the side is much more convenient to use. Strike 1.

It is honestly pretty rare for me to listen to something on my phone. The rare times I do use my headphones with my phone it's because something took out my internet while I was in a voice chat and I just unplug the headset from my laptop and plug into my phone to take my friends with me on whatever adventure it takes to investigate. Strike 2.

I already have a perfectly good headset with 3.5mm. Getting a whole new headset or even an adapter just feels like extra added cost for no real gain. Strike 3.

Bonus round. I can plug a 3.5mm headset into my Nintendo Switch while it's docked. Can't do that with USB-C. It's an odd thing to mention, but I have made use of that enough times to bring up.

Bonus bonus round. I have tried giving bluetooth a chance, but every time I'm massively let down. Initially things sound fine, then the moment I connect to a voice chat it's like I'm listening through water or something. Maybe it's the bluetooth headsets in my price range or maybe it's just bluetooth not being good in general but I can't work with that. I have a hard time with my hearing. I need people to be as clear as possible and I know for sure I get that with a wired headset.

Are there any waterproof USB-C headphones?

I use my earphones for both my PC and my phone. Seems kind of dumb I have to disconnect the dongle when I go from phone to PC and vise versa.

Its just simpler, and plugging a round plug is simpler than a rectangle. If all heaphones and audio stuff was already USB C then I probably woudnt disagree. But they are just overcomplicating stuf

Spoken by someone who only has USB-C laptops and phones. I have a lot more equipment that outputs audio, plus, all the good hardware either has a 3.5mm, 6.5mm or a 2.5mm plug.

Are there already any USB-C earphones with an L-shaped connector (90 degrees)?

The jack works and I don't have to buy another dongle/cable for my headset to work. I have to use an iphone for work, so I connect that to Bluetooth and everything else is connected through the audio jack on the headset.

I'm not a fan of bluetooth, I find the headphones heavy due to the battery which hurts after long use. 3.5mm is much more convenient to use i find, and also much easier to replace if it breaks.

Due to my current phone not having a headphone jack i can't use my koss portapros, so I picked up a pair of kph40 utility, again from koss which use a USB c cable and they work great.
