Not really recommended for Porno Wanking – please keep in mind people still can see you even though you can’t see them.
Your Own Personal Private Theater–Anywhere, Anytime! Watch what you want, when you want, where you want. Slide your iPod®, iPhone® or most any MP3 player into the interior pouch and the attached 2.5x magnification screen helps give you a movie theater experience. Privacy side shields prevent others from seeing what you are viewing. Use on planes, while camping, at the beach, even at home in bed.
