Very bad purchase.
Let me start with the positives.

And now the negatives.
They have 3 audio channels. But they also have interference on all 3 audio channels. They are simply useless. The noise is frustrating even from a distance of 3 meters. The sound is not great anyway (I adjust the TV to maximum volume, hoping to finally hear all the sounds), it is not particularly convenient, and the battery life lasts an eternity. None of these would bother me, however, if it weren't for the countless interferences. We're not talking about a few interferences, we're talking about to the point of irritation. As if that's not enough, sometimes they turn off for no reason (fortunately, the sound does not automatically return to the TV). They just sit on their base and collect dust. They have no usefulness.

They are the best headphones without Bluetooth for TV audio output that does not have Bluetooth. Ideal for the elderly, the only negative thing I would say is that they are heavy as a headphone, but it is logical because it has a large battery

I have had them for a while, but I am quite satisfied.
The sound is quite good and the construction is great.
I use them so as not to disturb others while they sleep and to exercise, in order to stay focused without any other sound distracting me.
I would recommend them.

I have them for over a year, they are reliable and worth their money. Their main problems are that they become tiring after an hour of use and of course the radiation since they are wireless with a long range!

User-friendly. Good sound. You can distinguish the words well, even if the sound in the film is not clear. Very easy pairing. You can hear well even from a distance. They are worth their price. I bought them through Skroutz for 67 euros.

Sometimes there is a noise for a while while the green light indicating the connection quality of the headphones to the base flashes

I have had these headphones for about two years and they are very impressive. They have good sound quality and bass, as we are talking about Sony headphones which, for me, are a guarantee. Over these years, I have never had a problem with charging as they have an amazing battery life, and the most important thing is that they are wireless, so you don't have any issues with cables, they only have their base. The only downside is that they are not suitable for traveling as you will have to carry their base. I highly recommend them to anyone interested in high-quality headphones from such a good and reliable brand like Sony.

I was disappointed with their purchase. Mediocre sound with annoying noise when the voice is at high volume. Its architecture with the base - transmitter confuses more than solves the problem of cables. If you want to change the device from which you will listen to the sound, you will have to move and connect the base to the device of your choice, like a hole in the water. In hindsight, I would prefer headphones with a cable, and they would have better sound quality and be more user-friendly than this particular one. Considering its high price, avoid this product.

+ It has good sound for home use, it is comfortable, the sound turns off when you remove the headphones.
- It makes noise when there is no sound playing.

Although without previous experience in headphones and especially wireless, I think that these specific ones are very good and worth their money.
+Nice feeling in the ear
+Lightweight - the build quality seems very good
+The battery lasts long enough
+Very nice bass
+Good and very clear sound quality
+Very easy to use, install, and recharge
+Elegant

-After a long period of use, the ear gets a little warm, but it's logical
-I would like and believed that it would have more volume. You can easily handle having them at maximum when listening to music. I would like more dB (to the point where I can't handle having them at maximum), but obviously, it's because they are wireless. However, I don't think anyone will be able to handle it at maximum for movies.

I recommend them
