MacBook owners are familiar with MagSafe, the breakaway magnetic plug design that prevents damage if the power cable is yanked away from the laptop. Replug can help do something similar for 3.5mm headphone jacks. It features a flexible elbow and a non-magnetic breakaway plug tip that can protect your device from undue stress. Available in black or white standard 3.5mm versions and an iPhone version $12.95 each. Also available are cable extension versions and replacement plug tips.
