New JBL sound curve is the headline act in major upgrades to flagship Tour headphones and earbuds
London, UK, 23 April 2026 – JBL introduces a wave of updates to its range-topping
JBL Tour ONE M3 headphones and JBL Tour PRO 3 earbuds, delivering improvements in audio performance and user experience to new and existing listeners, as well as a fresh new colour drop.
The combination of premium design, high-quality sound and class-leading features has made the flagship Tour over-ear headphones and TWS standout performers since their introduction. But JBL isn’t standing still. Subtle yet meaningful changes reimagine the JBL sound curve for clearer, more accurate audio than ever before. This joins a powerful user-interface update transforming how you interact with the Smart Charging CaseTM and JBL SMART Tx.
Completing the updates is the introduction of a classic green colourway with refined copper accents, becoming the fourth colour option in the premium headphones lineup.
A more natural, more accurate sound curve
JBL introduces an update to its sound curve for JBL Tour ONE M3. Based on the industry-leading Harman Curve and extensively evaluated by ‘Golden Ears’ and controlled listening panels, the refined tuning has also been independently validated by Force Technology’s SenseLab.
The new JBL sound curve debuts in the Tour ONE M3 green edition and is made available via over the air updates for the current Tour ONE M3 models. Listeners will discover more controlled, natural bass alongside subtle enhancements to mid and high frequencies. The result is a sound that is clearer, more balanced, and truer to the artist. Immerse yourself in the music as voices feel cleaner, instruments more lifelike, and fine details easier to hear across the entire spectrum, setting a new benchmark for precision and clarity.
"The way people listen has fundamentally shifted with better hardware, higher-quality content, and smarter streaming making today's ears more discerning than ever. We are always striving to push the boundaries of sound performance and saw this as the perfect moment refine the JBL sound curve for our premium headphones. The new curve makes its debut on our flagship
JBL Tour ONE M3, designed to deliver the clearest, most natural listening experience we’ve ever created.” said Carsten Olesen, President of Consumer Audio at HARMAN.
A smarter, smoother, more intuitive experience
JBL introduced a new approach to the TWS earbud user experience with the launch of the
Smart Charging CaseTM and is rolling out an update to the interface of the JBL Tour PRO 3 case and JBL SMART Tx, designed to make interaction faster, clearer, and more intuitive.
The update introduces a combined horizontal and vertical menu system, simplifying access to favourite menu tiles. With enhanced graphics, larger icons, and refreshed typography, listeners will gain smoother access to advanced features, from switching sources to joining or creating AuracastTM broadcasts.
Key updates include:
- Larger feature icons with updated typography for clearer control
- Refreshed colour scheme for improved navigation
- Optimised layouts requiring fewer interactions

Inspired by heritage British motorsport and modern luxury trends, a deep green with copper accents brings timeless sophistication to JBL’s flagship Tour range. More than a colour drop, it’s a statement, designed for listeners who value performance, precision, and personal style in equal measure.
The green colourway will be available from mid May 2026 at select retailers and from JBL.com, JBL Tour PRO 3 for £279.99/€299.99 and JBL Tour ONE M3 for £329.99/€349.99 and JBL Tour ONE M3 with SMART Tx for £379.99/€399.99.
