A:AnswerIt is absolutely adjustable. This is a very nice headset. One of the best noise canceling. I have had the sony wh1000 xm3 and actually liked the sound of this set better (less bass but more up front mids and highs, the bass is adjustable to get pretty loud with the app though). Plus i like the build quality of this better (much less plastic) and it is smaller form factory (less cumbersome). The one thing i did buy was a hardshell case for this headset through a popular online website (cost about 15)if you purchase this headset you will absolutely enjoy it. Good strong bluetooth connection and connects 2 devices (which the sony's did not). For a great in depth video review jims review room for the pcx 550 is great and will give you all the info you need on this.
A:AnswerThey will work with a Bluetooth transmitter I used several transmitters with them and they still sound great remember when hooking up your TV to the transmitter use the optical the analog will give you a little bit of white noise
A:AnswerThey are suitable for your TV and it depends on your TVs Bluetooth rating if it's 5.0 4.1 there will be no lag anything lower than that you'll have lag
A:AnswerYou can't use the mic to communicate with playmates during game. But if you do not need the mic than Absolutely yes. I do not experience any log, and the sound quality is awesome.
A:AnswerI also have a small head and relate completely to your question. I have other headphones that don't fit me well and are frustrating to use. These Sennheiser headphones are adjustable and I find them to be snug on the smallest setting...very comfortable to wear. I would recommend them for sound as well as fit.
A:AnswerI haven't plugged these into the headphone jack of an AVR, but I have used the supplied 3.5mm cable with a number of other sources without issue.
