Sennheiser XSW IEM Set E-Band

I had high expectations when ordering this set from Sennheiser but I was very disappointed. There was a very loud noise floor that was as high as the signal itself. I tried all gain settings and multiple channels/frequencies with the same result. I tried it in four different locations and with multiple setups in regards of mixers, auxes etc. Nothing solved the issue.

I got a replacement for the first set and it had the same issues so I’m getting my money back and will upgrade to G4 or the Shure equivalent.
