Sony MDR-V6 Studio Monitor Headphones with CCAW Voice Coil

The good

The Sony MDR-V6 closed-back, full-size headphones sound great and are comfortable to wear for hours at a time. Their sound is also very well-balanced and crisp -- they sound great for the money.
The bad

With its coiled, pro-style cable and lack of an inline remote/microphone, some will find the V6s less mobile-friendly than more modern headphones.
The bottom line

They may be close to 30 years old, but the comfortable fitting Sony MDR-V6s are arguably the best-sounding headphones for under $100.
