Razer headphones with USB not working?

Hi i have this pair of some version of Razer hypersense headset (cant remember which one) it has the option to remove the mic from the headset and is also wireless with one of Razers USB’s but it wont connect and google isnt of anyhelp at all! They all say to ”just go into sound settings and choose it” but its not there and its not findable through bluetooth or any of the other wireless connections. I have razer synapse and they arent showing up there either?
