Theres no question about it, Plattan is a staple in our headphone collection. The perfect on-ear headphone, Plattan features a rich & secluded sound in a sleek monochrome body. Use the Zound Plug to share your music with a friend, or the built-in microphone & remote to pick up calls while on the go. When youre done, fold Plattan down to the size of your fist for easy transport & storage. You wont know how you made it this long without it. The Zound Plug is not really a plug, but a socket that lets you share your music with a friend. Simply plug another pair of headphones in via the empty outlet on the ear cap & enjoy. We know you take your headphones with you wherever you go, so we made sure to design ours to be fully collapsible so you can easily fold them down & be on your merry way. Most music devices today are also cell phones. Thats why all our headphones come with a built-in microphone & remote. Use it to pick up calls, or fast forward or rewind your music.
