I’ve had my ES 500’s for about 6 months now. Both failed (dead mics) at about 3 months and were replaced (with used units). Now the right one has failed again - same problem= dead microphone or Amp. (The chimes and bluetooth phone and music connections are heard well in both ears.) Still waitng after 2 days for Jabra response.
I read that others are having the problem too.
I believe Resound got a bad batch of michrophones … I have had 4 aids replace because of that problem … I am waiting for two Jabras to come back from Costco at this time.
The second set of Nexia’s seem to be working fine at the moment … fingers crossed 
I am still waiting to see how Jabra reponds. Bad electret mikes can happen. Bad customer service cannot.
P.S. I’m an EE and use electret mikes frquently. They are no longer rocket science.
Hello.
Do you have any update?
I’m have the same problem on the left hearing aid.
1 - I have found that the best way to contact them is by phone. email or chat just gets delayed in circles.
2 - I finally got them to agai replacboth units. The new 9rebuilt) ones work well. We will see how long. This is now my third set.

I have the same problem (again) the first time it fails jabra sent me a replacement, they sent me a partir (left and right) the right transmitter does not work, I used the first right transmitter instead, but once again it fails, the left one. Does anybody know what is the problem with the microphones? I saw on Amazon a hearing aid vacuum to clean the hearing aid microphone, etc. It’s postpone that the problem is dirt or something in the microphones holes?
Hi there!
Well I could resurrect my left hearing aid, I put it on a dehumidifier 3 times for 8 hours and it works. I hope you can use it, because before I used a vacuum cleaner to aspire the possible dirt and debris and it didn’t work, I hope you can solve it too.
My experience with Resound / Jabra aids is that tiniest bit of moisture causes the microphones to play dead.
If you sweat a lot or wear the aids in bed, sitting or lying against a pillow this can exacerbate the problem.
The solution is to regularly clean them and put them in a dehumidifier often even when they are working normally.
when the microphone inevitably goes dead I find 1-2 days in a dehumidifier is better than waiting 3 weeks for a repair / replacement that will suffer the same issue before long.
Also if you need a quick fix putting the aid in a tiny air-tight enclosure like a pill box on full volume for 5-10 minutes often works too.
