Un-boxing and first impressions:

The box is well designed and made and printed in English and Japanese, it appears that Shure have intentions to make an impact on the Japanese market with this product. The extra ear pads are a nice touch. The headphones come with the usual standard leatherite pouch, a detachable cable (nice touch) and the standard gold plated adapter plug. Although this is a shure product it is only designed in USA and the headphones are made in China.


The manual is multi-lingual and easy enough to understand. The build of the headphone has a solid feel and does not feel flimsy.

Listening has not been executed yet and this will be done later with my Opera Consonance Cyber-30 (2A3 tube) headphone amplifier connected to the Elekit CD player. But I have already been advised by the supplier that these headphones will require 150 hours of burn in before they reach their full potential.
