The sound quality and portability is excellent. It is a very comfortable but somewhat bulky fit. Volume buttons are very sensitive and allow for very high volume . . . be careful. This headset was accidentally fell from the dining room table, a height of about 35 inches and the retainer frame panels - held together with tiny screws - cracked. I spent 4 hours searching the internet beyond the manufacturer and could not find replacement panels. The inside adjustable arms on both sides that are plastic with a flat metal bar in the middle to guide the adjustable earphones also broke. It is made of very cheap plastic. Two years later it fell off the night stand, a height of 24" and the right earphone broke off completely. Very expensive for extremely poor material quality.
