JVC True Wireless In-Ear HAA4TB
12mm dynamic drivers and Bluetooth 5.3 power audio with up to 26 hours of battery life, and the lightweight body with pivot motion hooks provides a secure, sweat-resistant (IPX4) fit. Touch controls and three sound modes—Normal, Bass, High—offer useful customization, but call performance is notably poor, scoring just 32.9. Best for budget-conscious workouts where battery endurance and secure fit matter more than clear calls.
