Within a week, one of our headsets broke - my husband pressed the "on" button (maybe too hard, he used his fingernail) and the button popped into the headset and could not be retrieved.
He called the Customer Service number and spoke to "Dave." Dave was very understanding and immediately offered a replacement. He emailed me a return USPS shipping label, and we packaged up the broken headset in the original shipping box with all the paperwork.
I received confirmation from Own Zone when they received my package, to let me know they would be shipping a replacement. Within 10 days, the replacement arrived.
As far as my experience with their Customer Service, I feel they did an excellent job. We solved the problem with the loss of sound in the headset when we mute the TV. Our soundbar is now connected to the 3.5mm headset jack, which kills the TV speakers and provides sound through the soundbar. The headset transmitter uses the optical cable, providing sound only to the headset. If we don't want sound in the room, we mute the soundbar; this leaves the headset sound on.
We are very satisfied with this purchase and the service we received, and I am upgrading my rating to 4 stars.
Bottom Line: Yes, I would recommend this to a friend
