The JBL does work on some things other than the case...
Features of the JBL Tour PRO 2:
● True adaptive noise canceling with customizable ANC and ambient sound
● 10mm dynamic drivers powered by legendary JBL PRO sound
● Customizable sound experience with Personi-fi 2.0
● Immersive JBL Spatial Sound
● 40 hours total music playback - 10 hours in the earbuds with a further 30 in the case
● 6-mic perfect calls with VoiceAware
● Bluetooth 5.3, LE Audio compatible
● Oval Tube design with multiple ear tip sizes for comfort, performance and the perfect seal

Says it has the voice aware so I'm assuming it does the auto pause and activate ambient and resume your music and ANC when done talking. The press blurb says it for the M2 headphones but not for the TWS but voice aware should work the same in both.
