I don't know where the 12" measurement comes from, but the cable length itself (minus both connectors length) is 10.5" Hope this helps. **Q: Does this work for a talkbox?** A: This is a passive adapter which simply allows an audio cable with a male 1/4in. connector to be plugged into any audio device having a 1/8in. socket. There is every reason to believe that it will work with a "Talk Box" if that device needs such an adapter. **Q: Can this work in either direction, i.e., 3.5mm to ¼" as well as ¼" to 3.5mm?** A: Dear Amazon Customer, Yes, this MillSO 1/4 to 3.5mm adapter can work in either direction (3.5mm to ¼" as well as ¼" to 3.5mm).
