Our Verdict

Sony MDR-7506

Beats Solo Pro Wireless

The Beats Solo Pro are more versatile headphones than the Sony MDR-7506. The Beats have a much better build quality and an ANC feature that blocks out an impressive amount of ambient noise. They also have a much more stable fit, so they're less likely to slide off your head during light physical activity like walking. On the other hand, the Sony are wired headphones with a bright sound, which may be preferable for audio professionals.
