baby monitor Babymoov Premium Care

Hi! We recently bought the Babymoov Premium Care audio baby monitor. It costs €110 and Dreambaby recommended it because it's low-emission and has a huge range (1400 m). The product description also says it's noise-free. However... we're hearing a lot of static! Has anyone else had the same or different experiences with this monitor? If you've also had a lot of noise with this one, do you have any tips for a different audio monitor?

Best,
Annelies
