I bought a pair of 6ft cables because I wanted great cables for my new SM7B dynamic mic and the built in Cloudlifter preamp I bought it for. Although the cables fit the male side of the Cloudlifter, they do not "lock" together. (My old audio cables work.) I suspect this is due to the somewhat non-standard cable lock/unlock mechanism. This is disappointing! I love product innovation, but not when it violates design standards that ensure interoperability between devices. Now I have to decide whether to send them back or what.
