The Arpara 5K tethered VR headset, reviewed by Naomi Wu (Feb 1, 2022), uses Micro‑OLED 5K panels (2560×2560 per eye), 120 Hz max, 3514 PPI and 90% DCI‑P3 color, weighing 200 g plus a 75 g tracker (275 g total). Tested with SteamVR and HTC Vive controllers, the reviewer praised comfort and image quality but noted the 95° FOV trade‑off and requirement for a high‑spec PC (≈$700+PC).
