A:AnswerAbsolutely. My primary reason for purchasing these in the first place was to connect to my tv. I’m losing my hearing in one of my ears and had to turn the volume up on my tv and sound bar. I read a number of reviews on this and some other comparable headphones and although the reviews said that the sound reproduction was slightly better on one of the others (Sony), they also said that the Bose were the best for ear comfort (the pressure and weight of the headphones would not hurt your ears after a long period of time). That sold me and the review was absolutely correct...no ear discomfort. I was also concerned about the 20 hours of battery time vs the others but that has not been a problem. The headphones tell you how much battery time you have left each time you turn it on.
A:AnswerYes, my brother enjoyed listen to the sound & paired his as well. I'm really not certain about simultaneously. Maybe you can research that, sorry.
A:AnswerI owned the QC2 for many years and only replaced the ear cups after about 10 years. So my experience was better. These seem to be well made and sturdy, but hard to know if they’ll stand up as well or better than QC2 after just a few months.
A:AnswerCan't speak to the iPhone, but I've connected mine to at least 3 different Windows 10 laptops with no trouble at all. I've also had them connected to a couple of different iPads, an Air 2 and an iPad Pro as well as my Samsung Note 9 (Android phone). The mic works well for me.
Watch out for the well known charging issues though. https://community.bose.com/t5/forums/searchpage/tab/message?q=charge%20700
A:AnswerYou'll need something like this hooked to your TV to grab the audio channel and send it over BT.

A:AnswerI have charging issues with mine too. Looks like there is a well known issue with these. https://community.bose.com/t5/forums/searchpage/tab/message?q=charge%20700
