Sony IER-Z1R

The 5mm super tweeter in the IER-Z1R was developed to deliver ultra-high frequency extension with a new aluminium-coated LCP diaphragm and external magnetic circuit. Its ultra-fast response faithfully follows the fast dynamic transience of music, which provides you with live concert hall atmosphere.

At the other end of the spectrum, IER-Z1R's 12mm dynamic driver's diaphragm consists of magnesium dome and aluminium-coated LCP. 

Sony's full-range driver offers deep bass and fine mid-high sound – the perfect foundation for a balanced armature mid driver equipped with a magnesium diaphragm, silver-coated copper voice coil and gold-plated terminals.

These three drivers work harmoniously as one, realising high definition sound that reproduces even the smallest fading note. Sony's refined-phase structure ensures sound waves are aligned, through precision adjustment of the width and length of each sound path. 

Sony's acoustic work is bolstered by a crossover developed from thousands of listening tests. The dedicated film capacitors on the crossover give much lower distortion, while audio-grade solder is used throughout to ensure maximum signal transparency.

With a 4.4mm silver-plated copper cable included with a swathe of eartips and accessories to ensure a great fit, Sony's IER-Z1R stands to be an endless classic that will keep you captivated for the length of time.
