Got these earbuds for a little over six euros from AliExpress. They sound very nice for the price, I love the Y2K transparent skeleton aesthetic and most importantly for me, the earbuds can be detached from the cable, so if it breaks you can just get a new one for a few bucks. I've had to toss dozens upon dozens of earbuds over the years due to faulty cables so I really appreciate being able to swap them
Edit: You can also plug in Bluetooth adapters into the cable connectors, which is pretty cool. The adapters seem to be a bit expensive though so you'd probably want one of the fancier models
If you were willing to spend a bit more in the 20-30 dollar range, you'd probably be able to get really nice Chinese earbuds but I just needed something cheap for backup and these do very nicely
If you didn't spend 200-300 on them, you're not getting the real audiophile experience
