ZiSin 340 IEM 10mm 1DD driver, suitable for mid to low frequency pop rock music, used for music and studio monitoring IEM.

ZiSin 340 uses a 10mm single dynamic driver with a pronounced bass shelf and forward, extended treble; sonically it delivers thick, meaty low end with sparkly treble but recessed lower mids and occasional treble peaks. For pop/rock monitoring the 10mm DD bass and treble extension make it engaging, though the lower-mid recession and treble peaks reduce mixing neutrality.
