Firstly, I want to thank to @Baycode and Havi for sending me a free sample of theHavi B3 Pro1 in exchange for my honest review. Btw, I am not in anyway affiliated with Havi. I've burned my pair for more than 100 hours and the sound didn't changed dramatically during this period.                          ABOUT ME:  I'm a 37 year old guy who loves listening music as my forum signature tells. I listen to a wide variety of genre and artist from classics to metal. My portable music journey started with an Aiwa walkman and...

First I want to thank @DJScope and @golov17 for making me aware of the Monk. I'm using the Monk as my primary earphone from the first day I've got them. Because this is not an ordinary earphone that is bundled with some Chinese mp3 players. It was a quite shock when I first heard them. Actually I didn't expect the Monk to be this good and addicting.
