JBL x Under Armour - Tune 720BT

JBL 720BT. I'm in love with them, it's not overpriced for what is offered and can atend me just fine, bc it protects my ears but still allows me to listen if the dog is crying or growling and I can listen to music at the same time. I can't stand earplugs or anything that blocks my hearing completely.

I’ve taken good care of them for over a year, so this was unexpected. Is there any way to fix them without buying a new pair? They still work.

I have JBL 510BT or JBL720BT

JBL Tune720s, can’t do in ear so I go with over ear.

I also have some JBLs that I use daily: Tune 720BT. They wirelessly connect to two Bluetooth sources, have a built-in mic somewhere that works great for meetings, and have a cord that I can use on the airplane. They were <$50 on Amazon so I don't stress over them either.

I have JBL 720BT headphones. In calls they autoduck, ie they lower the volume of any non-call sounds whenever someone speaks in the call. I've looked everywhere to disable this. Is it maybe the case that turning off autoducking on my headphones? Or on JBL headphones maybe?

That's the way my HD350BT got a defect, bc I used them for running and gym. I have a pair of JBL720BT for workout but am looking for something better. I thought the Accentum would be a nice play but after reading the comments, they are also not the best bet?
