Review on Sennheiser wireless headphones CX 6.00BT, black by Adam Nowak ᠌

I've been using it for 1.5 years, no complaints. I was pleasantly surprised by the current price 😈, I bought it for 3890, but with a 50% discount, thanks to the previous large purchase, it turned out to be 1945 😋. What is a profitable investment? What I wanted to especially note: these are the only wireless headphones (I now have 3: these, philips and a fake for Airpods) that connect to two devices at once! It's a pity not by three :) It would be cool to have a bunch of MacBook-ipad-iphone. But it's so good too. I specifically found the characteristics to see how this function is called, but this is not mentioned. I would like to buy full-size ones with the same property, it's not clear how to define such headphones.
