JBL Tune Flex ✓
ANC utilises more advanced technology to reduce unwanted ambient sounds. ANC works when, it detects and analyzes the sound pattern outside and inside the earbud and then generates a mirror signal to cancel it out. In simple terms, it's like taking +1 (sound from your surrounding) then producing -1 (inverted noise) to make zero resulting in a reduced level of noise.
The JBL Tune Flex have Active Noise Cancellation allowing you to listen at lower volume levels, good for your ears as you don't have to crank up the earbuds volume to overcome background sounds.
Jabra Evolve2 Buds too have Active Noise Cancellation making either of the earbuds ideal for plane rides and rush hour commutes. Each work with different noise cancellation settings, pick the setting that you prefer for travel or that enhances your relaxation time.

Highest Frequency
Jabra Evolve2 Buds
20,000Hz
JBL Tune Flex 20,000Hz
JBL Tune Flex's highest frequency is at 20,000Hz, high-frequency response indicates how well a particular audio component generates high audible frequencies and if it changes to the signal while at it.
