Dongle Dangler Keychain

The Dongle Dangler is a keychain accessory designed to securely hold your Lightning or USB-C to 3.5mm headphone jack adapter cable (dongle*).

Dangle your dongle on your keychain and never be without your music.


Pretty much a requirement on any persons key chain now who has a phone with no 3.5mm jack.

I keep this on my keychain so I've always got an iPhone headphone to lightning adapter on me. It's useful so I don't have to ditch my existing headphones and can allow my iPhone to jack into my car and other speaker systems that aren't Bluetooth.

One day we will look back at the dongle and laugh about how ridiculous it was that apple made users carry around a dongle to plug in their headphones. But for now, this thing works! The dongle is so small and easy to misplace. With this device, I always have it when I need it! Definitely recommend!

*What's a Dongle?

A dongle is the band-aid of hardware. It's meant to make up for gaps in functionality or to add functionality.


The audio adapter cable that came with your phone is considered a dongle. The audio adapter dongle allows wired headphones to still be used. It does this by converting the 3.5 mm plug (found on the end of a headphone wire) into a Lightning or USB-C connector that can plug into a phone.
