Sony WH-CH520
Up to 50-hour battery life and a 3-minute quick charge yielding 1.5 hours of playback pair with DSEE audio restoration to elevate compressed tracks. Multipoint Bluetooth 5.2, customizable EQ via the companion app, and a lightweight build with soft earpads and silent joints provide day-long comfort and seamless switching between devices. These are best for budget-conscious listeners who prioritize marathon battery life and casual all-day wear for music and calls, not fitness use.
