An update on my Vario Novo's is in order.

I sent them back,and asked for a refund, which was done without any problem. Full marks to Vario for that.

The issue that caused me to return them is strange, though. 

After wearing them for about four hours, over consecutive days, I noticed some white, powder-like substance on both units. My immediate thought was salt deposit from evaporated sweat, but highly unlikely. The weather had not been particularly warm, never mind hot, the part affected is outside the ear, open to air, and my shooting hat does not cover my ears. The batteries were new, from the pack supplied.

When I arrived home, and opened the battery compartments, the substance could be seen right inside the unit. I then thought battery fail, but two, at exactly the same time?

The decision to return them was made.

 

A shame as I was getting on OK with them.

This is something that can happen with zinc-air batteries.
I’ve seen this with multiple brands, incl. my own set from Siemens.

Always open up the battery compartment when storing them, this to prevent damage to the ear plugs.
Ever since I open up the battery compartment before storing them, it never occurred again.

The battery compartments were opened every time the plugs were not in use.

It seems to be dried electrolyte from the batteries, so I expect it was battery failure.
Did you get any reply from Vario, or didn’t you report this issue?
 

As I stated in the update, they were returned, and a full refund given, without a problem.

Vario said that they were unsure what had happened, but had sent the batteries somewhere to be checked for failure. I have not heard anymore from them.

I would agree that it does look like battery fail. It seems strange if that is the case, as it was both batteries, at the same time. They were the third pair of batteries, from a pack that came supplied with the plugs. No issue with the first two pairs. I changed batteries after 10/12 days, each time, before they dropped voltage below working level.
