The JBL Tour ONE M3 headphones and Tour PRO 3 earbuds are getting a quieter but more precise upgrade. A newly tuned sound curve—grounded in Harman’s Golden Ears testing and validated by Force Technology’s SenseLab—delivers clearer bass, livelier mids, and finer high-frequency detail without overpowering the mix. At the same time, the Smart Charging Case interface gains a horizontal-vertical menu system that speeds up source switching and Auracast management.
This isn’t just a color swap; it’s a re-tune of what JBL calls its flagship sound curve. The change debuts on the new green edition—deep green with copper accents—but rolls out over-the-air to all current Tour ONE M3 models via firmware 4.8.0, already live. Earbud users will see the same clarity gains when the case’s UI update (version 4.9.x) arrives this week and the SMART Tx transmitter interface (7.x.0) follows on April 30.
For listeners who value precision over punch, the new curve is designed to feel more natural across genres—cleaner vocals, more defined instruments, and less bass bloom. The interface tweaks are equally practical: larger icons, refreshed typography, and a dual-axis menu that cuts through nested menus with fewer taps.
- Sound: Revised Harman-based curve (firmware 4.8.0)
- Case UI: Horizontal + vertical menu system (version 4.9.x)
- Transmitter: SMART Tx interface refresh (7.x.0, April 30)
- Colorway: Classic green with copper accents
The green edition is now available at select retailers and online for €349.99; the bundle with SMART Tx is €399.99. Existing devices receive the updates automatically, so there’s no rush to upgrade—unless you want that heritage-inspired green finish.
