Thanks. What is 5.1 and 7.1? I am using a MacBook Proi so I cannot add sound card. In this case, are Sennheiser HD 650 or if on a budget the HD 600 or the Momentum HD still the best one? They seem to be quite expensive. How about those cheaper Logitech ones such as the G933 or H51/H340?
Is it better to get a wired version in case wireless connection fails in the middle of the interview?
