I'm looking for headphones that have a detachable cable, meaning if the cable gets caught on something it will detach from the headphones without causing any damage to cable or headphones. Do these have that feature? Thanks.
Asked by: Bob
Yes the cable for the AKG K240 MKII Professional Semi-Open Stereo Headphones is detachable.
