Our Verdict
Sony WI-SP600N Wireless
TOZO NC7 Truly Wireless
The TOZO NC7 Truly Wireless are better headphones than the Sony WI-SP600N Wireless. The TOZO have a more balanced sound profile compared to the Sony's bass-heavy sound. They also have better noise isolation, especially against bass-heavy background noise, and their continuous battery life is longer. However, some listeners may prefer the Sony's neckband design, and they have more sound customization features thanks to the graphic EQ and presets in their companion app.
