im not sure using them with a phone would be good in the long run, especially when you are moving around a lot more with the phone in your pocket. the usb-c connection isnt as tight as 3.5mm so its going to put a lot of strain on the usb-c port. if that goes on a phone youre in big trouble
But i realize that it might be hard to have 3.5mm on phones due to insane amount of size optimizations on these sophisticated devices we kind of take for granted by now.
I don’t find wireless (AirPods) all that convenient, so when they inevitably die of battery illness I’d like a pair that won’t suffer the same fate.
The only real downside is lack of ANC, and the wires can transmit some mechanical noise if it rubs on your clothing. I just have a little lapel clip (from my old Etymotics) to stop them moving.
Meh. If you want your headphones to last for ages, you could go just a bit higher end and get a pair with a replaceable cable. Then you can just swap the cable with the integrated DAC, regular 3.5 mm jack, or whatever.
I used to have a lightning cable for my Shure IEMs, worked great until the cable developed the usual problems around the connector, just like your regular analog cables. I then bought a BT adapter for the same headphones and never looked back. I've had them for 15-16 years now, still work as good as new. The BT dongle is something like 6 years old, and the battery still holds a good charge.
My adapter is a bit of a pain nowadays since it's the last thing I have that uses micro-USB for charging. I hear Shure has released newer adapters with USB C and no wires at all. But that's too expensive to replace something that still just works.
