Just a heads up, you might want to adjust your price on the headset. Amazon is selling "renewed" units for $25 ($30 if you want the USB to 3.5mm dongle for 7.1 surround sound).

With that said, they are great headphones for the price. I bought a pair for work a few weeks ago and just ordered another pair for my home setup this morning. Highly recommend them.
Hs50 for $20 also here
Refurb HS50's are also always available on Amazon for $25. Same headphone sans the USB interface.
Trying to fit your budget (20$) I found 2 options on Amazon:
Ps: Both have Amazon warranty if you have any problems.
Take care 👊
idk, literally any headphones that have a decent rating/brand and aren't super cheap crap
like https://www.amazon.com/CORSAIR-HS50-Headset-Discord-Headphones/dp/B07KFR2DY4/
https://www.amazon.com/Audio-Technica-ATH-M20x-Professional-Monitor-Headphones/dp/B00HVLUR18/
look up more, compare, etc
You can still get the HS50 for $20 or the HS70 for $35
