Query: They're so cheap, I had to give them SOME stars

I bought these mostly because of the relatively low price compared to other active noise canceling earphones. They do a somewhat reasonable job of reducing airplane/train noise, but the audio quality is pretty bad (unless you listen to everything at low volume and your musical selection has a low dynamic range.) With the volume set loud enough to hear the soft passages, the loud passages are totally distorted. And the double wires coming from the control box to the earpieces just adds to what is already a tangled mess with almost all earphones. Save your money and get some decent earphones; you really do get what you pay for.
