First, the application does not detect them as the model they are. This wouldn't be important if the battery didn't last for seconds. It can't hold a song: the headset on the right goes from being 100% charging to shutting down in less than a minute, the one on the left holds up a little longer but without finishing what lasts a song. The earpiece on the right many times or load. These headphones are completely broken from Origin and I don't seem to be able to make a claim. Total disaster. By the way, these are the rooms I buy and the previous ones work perfectly.
For the iPhone there is no rusified application, accordingly, it does not work to configure them for individual settings. Headphones "live their own life", put themselves on pause, the right earpiece often stops playing, have to get several times from the ear and back to insert. In the conversation mode of the incoming subscriber, it is audible very quietly. Whatever a good sound and noise reduction system, Bluetooth 5.0 and so on, and TP, if the headphones themselves become pause or turn off the collar, then the sound of the noise reduction is is is The general impression is latitude! And no matter how much they cost 10 or 1000 $ Must Work!!!! By the way, the box is different in design from other reviews. Maybe I was faked... I don't know.
Before Perm, the order was 3 weeks, the box is a little crumpled, but not critical. With 6 iPhones, they were quick, the sound is good, as in the conversation on the phone they show themselves while I can not say. In general, I like it very much. I did not communicate with the seller, but I can recommend it
