1More Aero ✓
ANC utilises more advanced kind of tech to actively counter noise. ANC works when, it studies the sound pattern outside and inside the earbud and after generates a mirror signal to cancel it out. Simply put, it's like taking +1 (noise) and adding -1 (inverted noise) to make zero which results in a reduced level of noise.
1More Aero have Active Noise Cancellation enabling you to listen at lower volume levels, good for your ears as you don't need to crank up the earbuds volume to overcome background sounds.

Highest Frequency
Sennheiser Momentum True Wireless 3
21000Hz
1More Aero 20000Hz
The 1More Aero's highest frequency is at 20000Hz, high-frequency response indicates how well a particular audio device makes high human frequencies and if it adjustments to the signal on its way through.
Sennheiser Momentum True Wireless 3's highest frequency is at 21000Hz, this implies that
Sennheiser Momentum True Wireless 3 can produce a clearer and crispier treble than the 1More Aero
