Sena 20s evo issue

[Shaunpaul]

Hi, currently have 3 sena headsets paired on our helmets running daily, however, at present we can hear machine/saw noise way more than verbal chat almost to the point they are useless for talking. I’m sure they’ve not always been like this. Anyone else had this issue? Do they need a reset or replacement? I’m at the point of throwing them through the chipper. Any recommendations for comms, are Protos worth the money?.

TIA.
