Oticon Agil crackling noise

Just into day 3 of a 2 week trial of RITE Oticon Agil Pro’s with custom mold and it has started crackling. Changed the battery, and i noticed it is fine for a couple of minutes then it starts: bip bip, bip bip, bip bip,…

Anyone know the problem - will of course go back to the Audiologist tmr to get it fixed.

Could be a lot of things, doesn’t really matter what. Like you said take them back.
