The metal alloy construction on the Pioneers gives it a sturdier feel compared to the plastic on the Sonys

They have a Magnesium alloy that make them VERY light based on other Headphones, they have a Protein Leather that is very soft and give you a good feeling, the cable is very well build...(long lasting Product) and is GOLD plated!Quick comparison with Studio BEATS by Dr. Dre and Pionner HDJ 2000:Beats got more Bass responce -> Pioneer

The hi-hat frequency (around 7-8khz) is unchanged, giving DJs a better feel of the beat, and the bass is boosted a bit making these indeed great for DJing
