this is my 3rd pair in 3 years and they continuously tear in the same place below the thong area. In addition to cutting the hair to ALMOST skin level (it leaves behind stubble), it has a tendency to yank and pull which I cant imagine being very comfortable anywhere else on the body. Quality of construction is Solid, the metal band is sturdy, while the ear-pieces are made of thick plastic. Battery is also nice. I wear a 7 3/4" hat, so I dont exactly have a tiny head and these are still very comfortable. La confezione è molto bella; allinterno si trovano cuffie, tappi per le orecchie, caricabatterie e istruzioni duso. Instruments are well placed and easy to pick out. I plugged it in and it worked. No sliding off the back, no crunching of the foot. The FM Radio Stations are very clear and are so loud we had to turn it down a few times to talk to one another.
