It’s funny.
When I started DJing, the only headphones most DJs went for were the Sony MDR-V6. When the silvery MDR-V7 and the copycats came out, everyone flocked to them…yet one by one they kept breaking easily at that one joint.
I’m strange now. After going through three sets of headphones in a short period of time (I don’t abuse them either), I look at construction as the most important thing. All the sound quality in the world seems meaningless if the design flaw found in most of these headphones keeps breaking them within 1-6 months after purchase.
