OMG…Let's start with the setup: It's practically plug and play. I went for the fiber optic hookup, couldn't have been easier. My hard of hearing wife, loves loves loves these headphones, I do too. Our kitchen and living room is in the same room, needless to say, we have to keep the TV at deafening levels (sorry, use to) to watch TV. We can listen to TV with headphones and simultaneously, without headphones. Each person can set their own volume level and each can mute at any time. OK, here's what I found annoying but fixable: Headphones are very snug, you're phone will help you find a fix. Wife's is fine, my are opened up across a few books to help "wear them in". The warning online is, don't stretch them too much at a time. Next, luckily I have two USB outlets on my old TV for power to charge the headphones and power the transmitter. Avantree doesn't put power chargers in the box, because of some crap about saving E-waste on the environment. Very noble and very inconvenient for the consumer. I had to buy them anyway. Next, the charging cord for the headphones is a 1 cord split 4 ways, and each headphone cord is 1-2 feet too short. ALL FIXABLE.
No major issues. How did I live this long without this Quartet (probably be a sextet before long). Thanks so much for the great product. I can't imagine every needing a hundred headphones but, 4 is a great start, add on anytime. If I had kids at home, we'd each have our own. Phone rings, don't care, barely hear it…LOL….JT
