Oticon OPN 1 have been excellent hearing aids
I purchased a set of Oticon OPN 1 in April 2017 from an online retailer. I was told to expect the hearing aids to last 5 years. It has now been over 6 years and the hearing aid are still working perfectly. I love the Bluetooth connectivity with my phone. It is much easier to have conversations on phone via hearing aids. I would highly recommend these hearing aids. The only reason I didn't give these hearing aids 5 stars is because they don't do well with moisture - possibly that is the cause with all hearing aids. I can't wear them when exercising because sweating causes them to stop working. Otherwise, they have been perfect.
