Adapter required

Yes — coming from South Korea, you will need a travel adapter for Oman. South Korea uses Type C/Type F plugs, and Oman uses Type G, so the pin shapes will not fit any wall socket. The mains frequency is also different (60 Hz vs 50 Hz). This rarely matters for electronics but can affect motor-driven devices like clocks and shavers.
