Beats Flex Black
Score: 73/100
Tozo NC9 with ANC
Score: 82/100Rankings
The TOZO NC9 earbuds deliver hybrid active noise cancellation, six microphones, and an IPX8 waterproof rating, backed by a massive 59-hour total battery life. Trade-offs include the absence of wireless charging, modest single-earbud runtime, and no high-resolution codec support. They are ideal for fitness enthusiasts, travelers, and budget-conscious users who want ANC and rugged durability.
Beats Flex are lightweight neckband earbuds that provide 12 hours of battery life and a convenient magnetic design with fast-charge capability. They lack ANC and have an unclear water-resistance rating, which may limit use in sweaty or rainy conditions. Best for active users who value simplicity, Apple integration, and long battery life over advanced noise-control features.
