The Fnatic version of the aiaiai TMA-2 headset is on sale for $79.99 on the fnatic website. I've had my eye on this for a while and price finally came down on it. Compare to $129.99 on Amazon.
This is a really cheap way to get into the aiaiai modular headset ecosystem with the cheapest model from aiaiai being the All-Round Preset at $145. Added bonus is you get an additional boom mic cable in addition to the standard cable to use for gaming or video conferencing.
