There?s a bar soap for comparison on size. Only suggestion to the manufacturer is the microphone head has some distinctive smell to it and it bothers a little when I was trying to sing to it. Not far from the sound that one of the very best headpones currently available would provide. Nicely made, warm, reasonable price. I adjusted it using the Stevenson protractor to make sure, but, the results were the same: flat low-quality sound. Also the buds come dirty with wax. They dont work and randomly shut off. The microphone, Ive been told by those I talk to using it, sounds great and is relatively clear. However the top of my feet feel like they have super deep bruising from them not fitting tightly around my feet. The traction seemed to have a nice grip on that surface.
