I’ve a trusty paint of headphones I’ve had for ten years or so and used to use them when playing my electric drum kit, the long cable was particularly useful at the time but now I use them almost exclusively at my desk the cable is proving a pain in the neck. I have a Bluetooth headphone adapter I use at the gym so figured a simple hack may be in order.
I shortened the cable, added a loop for the adapter to clip to and job done. The end result is closed back headphones that, with an extension cable, can be used as normal and a headphone adapter I can still use at the gym.
Simple enough but fantastic sound quality and functionality by combining a few things I had lying around, saved my buying a new pair of wireless cans and gets more life out of kit that was underutilised.
