The Tequila is a slight v-shaped sounding iem that has an engaging and smooth bass reproduction yet still retains crisp highs. The midrange is slightly recessed with good details retrieval. There is a lively presentation with an open feeling. In addition, it comes with a quality detachable copper cable and the shells are constructed well with CNC metal alumiunium. The TFZ Tequila 1 is an unique looking iem that exhibits nice musicality.
