The JBL Tour One M3 Smart Tx wireless over-ears are reviewed as a feature-rich option offering good comfort, long battery life, and strong call quality. Key features include LDAC Bluetooth for higher quality audio and an integrated Smart Tx transmitter, which provides controls usually found in the accompanying app. The battery life is substantial, lasting up to 40 hours with ANC and 70 hours without.
Regarding design, while the M3 maintains a similar silhouette to its predecessor, it offers more color choices, including blue, mocha, black, and a new deep green finish for 2026. Reviewers noted that the headphones are comfortable, citing no issues with clamping force or general comfort, and they feel light despite weighing 278g.
The model supports various wireless technologies, including Bluetooth 5.3, SBC, AAC, and LDAC. Additionally, it includes Auracast for connecting to public area devices. The Smart Tx transmitter is a standout feature, allowing users to fine-tune performance through EQ settings, playback controls, volume adjustments, Auracast activation, Spatial Sound monitoring, and battery monitoring, reducing the need to use a smartphone.
This transmitter functions as an alternative to the JBL Headphones app, supporting real-time functionality and eliminating the need for users to constantly access their phones. Furthermore, the M3 includes additional functionalities such as customizing a lock image with a personal photo and offering a Relax Mode and a Silent mode, which turns off Bluetooth notifications while activating noise cancellation.
Performance-wise, the headphones offer multiple noise-cancelling modes, including manual and adaptive Noise Cancellation. However, the review indicates that the noise cancellation is not the strongest in the market, letting through noticeable cabin noise on planes and more noise than expected on public transport lines like the Underground.
