They also tend to get dirty really easily, would not recommend. I am profoundly grateful to them and to him for the advances they made in technology and artistry. 1 (Center speaker, 2 side speakers and a subwoofer), go for Bose Smart Soundbar, otherwise, my recommendation is 3. I got this one specifically because there is no back rest, a lot of reviewers on other products complained about hitting them doing pull ups, I think I made the right choice and not having that bar doesnt affect the stability of the tower at all. My last NBs fit fine. This case is really nice. People could always hear me crystal clear on the other end. Thre barrett dies quickly and does not last a full day even with minimal use. My only real problem with these shoes is that I ordered the size I always wear and have worn for years, but yet these are slightly long, possibly slightly wider than normal too. Slight pulsing tone when ANC is on and nothing is being played.
