Can anyone - from Canada or anywhere else - tell me why would you need to use this 3.5mm stereo plug to 3.5mm stereo plug adaptor? Joel Johnson has a possible explanation:
Yeah, I can think of a couple of weird scenarios (need to trick a jack that checks for stereo into accepting a mono plug), but nothing typical.
Seems like a very rare occurrence indeed. Other than that, any ideas before I file this under "Absurdly Stupid Adaptors"? [Thanks Karl!]
