Got one of these... It's an A4Tech...
I don't know the exact model but it say's "TruBass" on the box...
The bass side is has a triple purpose for me...
One as an earplug when I play drums...
Two so I can hear the drum beats more clearly...
Three I can share the music to the people beside me...
Cost me P250 only... Too bad the wires aren't that thick...
It gives me the chills because so thin it looks it may snap in a wrong move...
