The JBL Tour ONE M3 strikes a balance between lightweight construction and day-long comfort. Weighing just 278g, with a soft memory foam padding and intuitive headband adjustment, these headphones are built for long listening sessions. While the plastic finish feels less premium compared to rivals, the robust construction and smart folding design make them a reliable travel companion.

Beyond standard controls, the Tour ONE M3 shines with its Smart Tx transmitter, enabling wireless connections even where Bluetooth is unavailable. The comprehensive JBL Headphones app offers detailed sound adjustments, adaptive ANC control, spatial audio modes, and hearing profile customizations. Combined, these tools give users a deeply personalized and flexible listening experience, rare in this segment.

The Tour ONE M3 offers bold, punchy bass and a highly detailed midrange that brings vocals to life. However, the treble can become edgy, especially at high volumes, affecting long listening comfort. Spatial audio subtly enhances soundstage without losing coherence. At moderate volumes, the listening experience is energetic and detailed, but pushing the limits exposes some harshness and loss of composure.

The adaptive noise-cancelling system on the Tour ONE M3 impresses by reducing most external noises without disrupting sound quality. Thanks to eight integrated microphones and smart passive isolation, the headphones manage distractions confidently, although extremely loud environments still pose a challenge. Adaptive settings automatically adjust for optimal performance, creating a smooth and immersive experience overall.
