It's absolutely ridiculous that such expensive headphones (700s) come with no instructions whatsoever, and tries to force you to download this app (luckily you can just find instructions online). Have a look at how much this app tracks you, it's beyond belief. The audacity of charging a premium price for relatively mediocre headphones only to make even more money invading our privacy and selling our personal information. I will never ever buy a bose product again.
