r/Nuraphone

Anyone know where I could acquire Nuraphone eartips or has an alternative eartips recommendations?

I'm in Australia.

I have no idea what the retail price of nuraphones are but there is a pair of wireless nuraphones in outlet for 50€, i have no idea what model etc. They just looked really intresting to me and just found this sub so might as well ask if they’re worth the price!
