k70 RMA? - Keycap and switch sounds are inconsistent.

I've only had this keyboard for less than a month and I'm already getting weird sounds from some keys and the switches. (Brown Switches)

All keys with the stabilizers sound different to each other, my space and backspace key stabilizers make ping/rattling sounds that is more distinctive than the sound of the other keys with stabilizers and its really quite annoying because even with my headset on (1500v2) I can still hear it.

Many of the switches on normal keys have a sort of springy pinging sound that resonates for the tiniest bit after pressing the key. Even the less frequently used keys have this. Here is the sound of my caps lock.

Am I able to get an RMA for these reasons? And is shipping free?

I'm from the land uʍop ɹǝpun.

Thanks
