Build and comfort:   These headphones are built with quality materials. Original msrp of 149$ can clearly be seen here. A lot of metal is used. It doesn't work as well as it looks though. Part's that connect the hinges can be squeaky at times. It is caused by the spring inside the cups and metallic build emhasizes the sound. Headband is propably loose for most people. It is really huge. If Jabba The Hut was buying headphones, he would propably choose Pioneers. Luckily clamping force can be increased with easy headband mod.  It is explained here...
