Review on 🎧 Sennheiser PXC 550 Wireless: Advanced Noise Cancelling Bluetooth Headphones with Touch Control and Long Battery Life by Chai Charoen ᠌

After the purchase, I could not synchronize them with the iPhone Xs Max, after long dances with a tambourine and using an old android phone, I managed to ate the firmware, and how to connect my iPhone as a second phone. Further, instead of synchronizing with androyd, I connected them to a laptop, and used it for almost a year. Today I received a notification about the possibility of ating the firmware. I tried several times, but I constantly get a notification that the headphones are not compatible with iOS 13.4. I had to reset all the synchronization again, get the old android ated, then dance with a tambourine to ate the firmware. As a result of the ate, I decided to synchronize them with two iPhones (personal and work) and it turned out that the headphones CANNOT work with two iPhones at once, only one by one. As a result, I will continue to use my personal iPhone and laptop.
