So far so good! Now…..still good! after a year using every day for hours!
It is perhaps too soon to do a real review, but as far as the initial testing, it just worked fine. The connectivity was very easy and fast, buttons and switches are very easy and straight forward, and the product comes with minimal-but enough instruction manual.The headphones are comfortable and I had it on (one of them) for a few hours without causing any pain or sensitivity in my ear. The quality seems very good and feels sturdy both visually and touch.The only thing that concerned me was that one of the headphones, sound differently than others, being a bit more dull, deeper bass, and losing some high frequency compared to other headphones, it seems like someone has pre-set them a little differently.I wish headphones woulda come with a pouch or best with fit case.I turned everything on and connected in less than 2 minutes, and played some different videos and music videos and there were no lip-lag. The sound quality is not top notch but acceptable for the price.By and large so far so good, and not disappointed at all.I will update honestly if something pops up and as i said, it’s too soon for any reviews on durability and long run quality and stability.Update: I have been using only 2 of 4 headphones for long time now, these really rock, have been fully functioning without a hitch without any drop in quality. In my humble opinion deserve full 5 star, and so be it , changed 4->5

Avantree Quartet
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

Would definitely buy these again!
These work great for replacing the IR headphones that come with the GM infotainment system at a much better price than those IR replacements from GM. Plug it into the headphone jack and you can add additional headphones if you want to. The sound quality is great and the batteries last long enough to keep the kids watching movies for hours in the car comfortably.

Great for TV without disturbing others
The headphones are comfortable, makes it easy to enjoy watching TV without disturbing the whole house. Also, can easily watch even with lots of background noise without turning the tv sound up to blaring.The charging cables are a bit short. I ended up purchasing longer cables.

Comfortable and work great
Work great. Daughter did initial setup for me. Super easy to transition between regular audio and audio on headphones. (I did have daughter put photo step by step on my phone notes. After 2nd or 3rd time I don’t have to look at the steps).I like being able to have regular sound on and headphones for myself too. That way I am not blasting the volume on others because I miss what is said when background noises are to loud (either from music on movie or grandchildren playing nearby).Hubby and I like being able to watch TV without disturbing grandchildren after their bedtime. This was the main reason I purchased the headphones.

Lower end headphones, pretending to be luxury
1. Value for money is not justified- this is the most basic headphone anyone can buy for a lot of Money2. Very uncomfortable non-breathable ear muffs- Ears start sweating in a few minutes after you wear the headset.3. No battery saver- even the most basic headphones have a feature that turns the headset off when you take it off, this does not turn off until the battery is dead.4. No charging station and Not easy to use and it’s the most basic push a charger into its hole – unmanageable destroys the clean TV space

Works as advertised – fantastic product – deep base – nice controls on headsets
I can run all 4 at once without interference. I could not do that with two separate dual TV transmitter/repeaters.You can also use these as regular bluetooth headphones. Remember to turn off the transmitter when you try to pair with some bluetooth device or it will interfere with pairing.I charged these overnight at the beginning. They are still going strong after 3 long days of use.Support has been very helpful both pre and post sale.I can walk all over a 1400 sq ft home and hear them anywhere. This allows ‘watching’ TV without watching it for quick breaks, interruptions, or listening to music channels.With low profile earbuds, you can wear these headphones fairly comfortably and monitor the PC while watching TV. Just mute one or the other or try divided attention.My only problem is that they are not water-proof. I cannot wear them into the shower. 😉

I purchased for my projector which is set up outside in our verandah which has a metal roof and gets very loud when raining. They are amazing, easy to set up lots of options for connections, Bluetooth, optical or aux 3.5mm and made very well. Very pleased with my purchase and recommend to anyone who need to share audio for tv.

Sounds best on the clear voice eq mode, the balanced mode is very muddy.In clear voice, they sound quite good. Range is fair. Latency is great!Build quality is shockingly nice, transmitter feels a little cheap but the headphones feel great in the hands and are very comfy.

Ho cercato a lungo cuffie con queste caratteristiche… Dopo averle provate un po’ di volte, posso senza dubbio dare un voto:10 e lode… Facili da usare, intuitive ma soprattutto dal sound fantastico… Le ho collegate al mio proiettore per guardare film in terrazza senza disturbare il quartiere…. Sono fantastiche… Consigliatissimo
