First I recommend those new to discord use the phone app(it's free) with some regular ear bud headphones or possibly set it to speakerphone if you trainer is super quite. Phones these days have awesome sound cancellation technology all you get is clear conversation when setup correctly. After you figure out the phone and how well I should work you can then start messing around with discord on your laptop or whatever which seems quite a bit harder to do when you have to deal with third party peripheral and such. Hardy has more than a few bugs to work out with his broadcasting half of discord.
I have discord up on most days we use it for work People are welcome to schedule debugging with me. I concur you need a good wireless computer head set or a phone with ear buds that are sweat proof and have a microphone work the best. We use beats wired ones here and they work well.
