Repeat after me : Spark is my friend.

Why not choose an artist that you really do not like and never play, Justin Bieber, One Direction, Extreme Noise Terror, or whatever.  When not using your Phantoms for actual listening, repeatedly play tunes from your chosen artist that you really do not like, with the volume turned to almost zero, of course.

If after a couple of weeks you find Justin Bieber and Extreme Noise Terror in your Amazon 'Recommendations for You' section, then that's it, you've rumbled them!

(Please do not be offended by this post if you are a fan of Justin Bieber's music, I simply selected the name at random)

How shrewd is that!
