Hi guys i don't know if it's a common question but I don't know how to word it, so i might as well just ask

I've been thinking about buying a new earphone/headphones, and my friends recommend Blon or Moondrop, but both are IEMs and i notice that they can be disconnected from the cable

Does that mean that they can be wireless when disconnected or do i need to buy a wireless adapter for it? It's not that i necessarily want a wireless headset, but if it was it would be a bonus

thanks, and sorry if it sounds like a dumb question
