You can probably tell from the logo that these are tilted in the wrong direction. Still, this shot does illustrate the point that the FreePulse headband is so light that it has a hard time lying down. Above and below the logo you can see the up and down buttons for volume control.
The headband on the FreePulse headphones is not adjustable, but don't worry. Because these headphones are meant to be worn behind the neck, all you'll need to do is adjust the ear straps to insure that the headband is projecting away from your head and neck.
Sure, this looks like some kind of futuristic head vise, but in actuality, the FreePulse headphones don't rely on pressure against your head to stay on. Instead, the straps keep them lightly draped over your ears.
