The JBL Tour One M3 Smart TX in blue is a closed-back, over-ear headset designed for those who want high-fidelity audio and versatile connectivity. It features 40mm mica-dome dynamic drivers that deliver a wide frequency range from 10 Hz to 40,000 Hz, while the True Adaptive Noise Cancelling 2.0 system uses eight microphones to actively block out environmental noise. To make the listening experience more personal, it incorporates Personi-Fi 3.0 and JBL Spatial 360 Sound with head tracking for a more immersive feel. A standout feature is the JBL Smart Tx, a universal Bluetooth audio transmitter with a smart display that allows you to easily connect your headphones to various sources. The device is built for long-term use, weighing 278 g and offering an impressive battery life of up to 70 hours with noise cancelling off, or 40 hours when it is active. It supports modern codecs like LDAC, SBC, AAC, and LC3 via Bluetooth 5.3, though you can also connect using a USB cable or a 3.5mm mini-jack. Designed for comfort during long commutes or work sessions, the headphones include touch controls for managing volume, calls, and noise cancellation settings. The IPX2 splash-proof rating provides basic protection against light moisture. Along with the headset, you receive a carrying case and several cables, including USB Type-C to Type-C and an analog 3.5mm option, ensuring you can charge the 850 mAh battery in about two hours or connect to older hardware.
