It says headphones, but they are actually earphones

I can't for the life of me to find a frequency response graph. I can't recommend buying anything without a measurement since you would be buying blind

Here is how you should look for earphones:

1. Buy something with a replaceable cable so it lasts longer. The cable usually breaks first and it's the cheapest part.

2. You can buy DSP earphones with a replaceable cable, but I haven't found anything cheap that sounds as good as the 3.5mm connection (which means the DSP sucks). So buy a dongle separately, like the Apple one or something of similar quality

3. Find the frequency response graph. You can see how your current equipment graphs and compare. You can even use an equalizer (in software) to adjust to what you're buying

If you want my suggestion, buy CCA Trio and the Apple dongle. Although maybe it's expensive after tariffs, lol

KZ Castor for a cheaper option

Why not just an adapter?

I use a separate usb adapter to the earphones. iBasso dc03 has separate usb c cable that I've been able to replace when the original broke. Cheap replacement rather than tossing the whole thing away.

For earphones, I use kefine delci as they're comfortable for my ears and sound good enough. When the cable eventually breaks, a new pair is cheaper and the earphones can still be used.

I got a pair of KZ ZSN ProX that have a removable cable you can swap easily with a USB-C one. I had them for 4 years now and they're really durable: for the price (about 20$) the sound is insanely good and if you spend the extra 10$ for the cable you can plug them wherever you want.
Best purchase ever

If you're looking for in-ear monitors, I really, really recommend Crinacle's The Hangout. Dude's a legendary audio reviewer and The Hangout only stocks things that are good to him. Yes, that means that even his lowest-priced offerings are awesome. You won't go wrong at all with anything in that site.

For USB-C IEMs, I highly recommend the Moondrop Chu 2 DSP. It's $28, and phenomenal for the price.

The AKG Samsung earphones are decent, especially for the price.

To be honest, the standard Apple wired dirty buds are quite fine. according to reviews they seem to have a very good amp and their sound is very good too. You'll pay a bit of Apple tax, though, they cost around 20 €.
