Wanted: Sinch, A Magnetic Cord Clasp For Your Smartphone

Ever wound your headphones onto your phone? Sinch helps keep them there.

We’ve opined before about the pain of cord overload that makes our messenger bags look more like a vat of electronics spaghetti. But we still haven’t found a winning solution for making our headphones behave while keeping them close to where we actually use them. Enter the Sinch, a simple, good-looking solution for de-tangling our devices that’s designed by frog.

The Sinch’s magic is in its simplicity. An elastic band fitted with magnets slips through the audio connector on your phone or MP3 player. The strip flattens along the back face of your device, which means it won’t get in the way as you’re using it. When you’re finished using your headphones, simply wrap the cord around the device and use the magnetic strap to secure it.

Where most cord collectors allow you to bundle up your wires using spindles or Velcro, they don’t allow you to keep the bundle attached to your device, which is kinda the point—it only really helps to have your headphones orderly if you can find them quickly when the time comes to put them on. The Sinch allows you to wrap cords around your phones or tablets just like you normally do, but the elastic band helps the cords stay put. This idea is extra smart because it plays upon a certain action that almost everyone has done with their devices and it doesn’t add yet another bulky peripheral.

According to frog, the Sinch is also unique due to the firm’s collaboration with engineers at Dune Road Design. Instead of taking a completed concept to the manufacturers, the designers and engineers worked on an integrated team from the very early stages of development.

The Sinch is available in black or white for $15.99 at

    So now we have Sinch in Denmark. Excited to see how the design conscious and simplicity-oriented Scandanivian market will react to this product.

    The design looks cool but not necessarily useful on smart phones. We don't want anything obstructing the screen.  It would have been better if you could wrap the cord in a circular motion on the BACK  of the phone, not going over the phone's front. Also most user population uses some sort of bumper or cover that are non magnetic.  No clever device ever solved all the problems 100%. In this case this is another good cord bundling gizmo.

    I'm a fan of solutions in this space. I really like the design, I bet the magnetic action has that magical feeling too, very cool. 

    For me the kicker though is winding. Time spent winding is similar to time spent untangling.  If your point of view is similar, checkout, no winding, just slip, stash, done. there is a sale going on too..

    For smartphone users the answer is really quite simple - bluetooth! I was rather dismissive of the tech for delivering decent sound but was quietly impressed by the Jaybird designs teamed with my iphone are perfect for the London commute

    Tim is right. I wonder how the author Alissa couldn't see this flaw. Maybe it's only the design which counts ... practical matters are of no interest.

    I think this design is brilliant for an mp3 player...but I question how useful it really is for a smart phone. Wrapping the wire around the old iPod works great because with the old iPod you ALWAYS use the headphones; every time you pull it out you are do so with the intent to listen to something. But I would wager that most people with a smartphone, or even an iPod touch, utilize applications that don't require headphones  (web surfing, texting, email, etc.) as much as, if not more than those that do. So while keeping the headphones close by may still be smart, having them wrapped over the screen or dangling from the back may be solving one problem and adding another.

    Magnets on my smartphone? Nah... otherwise, love the rest of the design if it's well-executed in practice.

    hmmmm looks as if it could come off easily though, especially if it would be in my purse which it would often be.....  magnet or no magnet :-(
