Title: Total Trash
Review: The sound is terrible and noice cancelation simply doesn't work. Not a little. Do not buy! I wont be surprised if I find out that this thing that looks a mic for noise cancelation is not a mic. The only thing this thing does is to amplify the sound by using a battery, but if you turn off the music and keep it on, with ambient noise, you'll realise that is has ABSOLUTELY NO EFFECT.
