They are not worth it. Sound quality is good, I like it, but not as nice as my old Bose Qc3's. The sound is much better than any Bluetooth headphone that I have tried.
But the biggest draw back is that you cannot charge while using them and these things use a lot of power, at least on my phone anyway. For me, about 10% an hour extra. If there was wireless charging then there might be a benefit. But you either charge or use the port for sound with a large discharge.
People cannot hear me when using them to make a phone call. I have to hold the mic up. Not happy about that either.
the noise cancelling is OK but I hear a constant sound like air blowing and I get a little of that pressure in my ear like you get from a cheap pair of noise cancelling headphones. The app lets you turn off that feature.
When I plug them in, I get a pop up saying something was plugged into the usb port and I have to confirm it. That is a joke and another pain in the butt having to deal with it.
I am sure this will be the problem with the iphone too when vthey do away with the headphone jack.
