What are these? I’ve never heard of them.

Which one is better the steelseries arctis pro wireless or astro a50 3rd gen I’m one ps4 only

The cheapest astro is 104$ Used And the hd 558 128.99$ used Modmic 69$ new no used Plus international shipping 60$

I’m kinda afraid of buying something used cause it might be defective or doesn’t work properly And even if I could return it it would cost me a lot for shipping charges cause I’m not from the US
