Cros aid has loud background (white) noise

Hello,

I saw a few posts about some people experiencing background noise with Oticon devices. Has anyone specifically experience with oticon CROS? Is the noise absolutely unavoidable?
I am testing right now and the audiologist took a lot of time to fine tune it for me but the noise still so loud.

Are there any devices from other producers that have the same amazing sound but less or no white noise?
