Tennmak Dulcimer Review – Noteworthy!
Tennmak Dulcimer—deceptively modest in appearance, these are actually very noteworthy. A slightly bright, well tuned, forward basshead signature; very detailed despite their huge, thick (though controlled) bass presence; mids are recessed but nonetheless crystal clear and uncolored Treble shows surprising extension; only a slight high-end graininess at higher volumes distinguishes them from much pricier IEMs. Bass is actually tighter and better articulated than the (slightly) pricier Pros or Pianos, although soundstage is considerably smaller. Light, very comfortable and easy to drive. A classic example of price/performance gone awry.
JK adds: The Tennmak Dulcimer is a single-dynamic driver earphone with a frequency range of 20-20000 Hz. I purchased mine for below $14.
