We have all damaged our wired headphones by accident in the past. JackSafe aims to change that. It is a magnetic audiojack that protects your headphones and reduces the wear and tear on your audio connector. The connection is strong enough to hold even when you are engaging in outdoor activities.
JackSafe can be connected to any device with a 3.5mm headphone jack. It also fits various phone cases. Expected to ship in April. More info is available here.
