And so, here will be purely my opinion and experience.
1) Sound. After airpods 2, it will memorize as if there is a film / door between me and the music. Fuck knows how, but they sound like Chinese junk for 300.
2) Connection. Without a market, I opened the case for 3-5 seconds and on your screen the coveted connection window, but that's where it ends. If you still use Apple Watch (I have 4) and how I answer the phone from them, then here is the next minus. If you connected them to one device, then these headphones will only be with him. That is, they, like airpods, do not spin in this ecosystem. If you listened to music from the watch and suddenly you received a voice message on your phone, then you will either have to take out the earpiece and bring the phone up to listen, or reconnect the headphones to the phone and back.
And yes, be prepared for interference and disconnections.
3) I don’t know what to call this item, let it be independent 😂 If you listened to music and put one earphone into the case for charging, then when you turn on the music, the music will play both in the case and in your ears. I don't know why they don't cut off. And I don’t know if it’s important to you or not, then if you take the earpiece out of your ear, then you are not the owner of it and it will continue to play music, even if you put it in a case, you cannot defeat it!
4) Management. The on under the glossy surface of the earpiece is located on the corner of the earpiece, where above the letter b. When you want to switch something, your finger slips, so you have to hold it.
5) Convenience. The size of this g case will take up 1/2 of your pocket and your living space in the apartment. And the headphones stick out of your ears as if you want to catch a connection from space.
6) Communication. Be prepared for the fact that the connection between the headphones and the phone / player / watch will disappear for 15 seconds, while they themselves will reconnect SEVERAL TIMES.
7) Functionality. There is nothing to say about noise reduction at all, because it is simply not there. Earplugs for 15 better deal with this. And the transparency mode is like a child with a bag in his hands is playing near your ears.
The rest is in the comments.
