Original Retail Box WHAT IS IN THE BOX Sony MDR-EX650APT Earphones with Brass Housing, Smartphone Mic and Control - Gold/black PRODUCT DESCRIPTION Sony MDR-EX650AP Earphones with Brass housing and Smartphone Mic and Controls made in brass for a clear stable sound with reduced resonance - hear every note with more clarity and less unwanted vibration. Sony MDR-EX650AP headphones use brass housings to minimise distortion and wide brass ducts for high sound stability and with an angled earbud design that fits securely in the ear, you’ll hardly notice you’re wearing them. Minimises distortion in brass - with a similar density to steel, brass is an excellent metal for suppressing unwanted vibration and keeping sound stable. The brass housing used in these headphones resonates less than housings made from more traditional materials for clearer mids to highs and smoother low frequency sound. Clear and stable sound - in the search for higher stability and clearer treble, expanded brass ducts have been used with a 15 per cent larger inner diameter than those found in conventional headphones.
