✓
Sennheiser Momentum True Wireless 3 ✓
ANC uses more advanced kind of tech to actively counter noise. ANC works when, it detects and analyzes the sound pattern outside and inside the earbud and generates a mirror signal to counter it. In simple terms, it's like having +1 (noise) then adding -1 (inverted noise) to make zero resulting in a reduced level of noise.
Sennheiser CX 500BT have ANC enabling you to listen at lower levels of volume, causing less ear fatigue as you don't have to crank up the device volume to overcome background noise.
Sennheiser Momentum True Wireless 3 too have ANC which makes both earbuds ideal for plane rides and rush hour travels. The Sennheiser CX 500BT and Sennheiser Momentum True Wireless 3 operate with different noise cancellation types, pick the mode that suits your commute or that suites your chill time.

Lowest Frequency
Sennheiser CX 500BT
5hz
Sennheiser Momentum True Wireless 3 5hz
Sennheiser CX 500BT's lowest frequency is at 5Hz, low-frequency response measures if and how well an audio device produces low frequencies that can be heard, and if it makes any changes to the signal on its way through.
Sennheiser Momentum True Wireless 3's lowest frequency is at 5Hz, this implies that
both devices produce equal bass
Highest Frequency
Sennheiser CX 500BT
21,000hz
Sennheiser Momentum True Wireless 3 21,000hz
The Sennheiser CX 500BT's highest frequency is at 21,000Hz, high-frequency response measures if and how well an audio component makes high human frequencies and if it makes any changes to the signal on its way through.
Sennheiser Momentum True Wireless 3's highest frequency is at 21,000Hz, this means that
both devices produce equal treble
Sound Pressure Level
Sennheiser CX 500BT
94db/mw
Sennheiser Momentum True Wireless 3 107db/mw
SPL, is the level of pressure of sound, in decibels, dB, Sennheiser CX 500BT's measurement is 94dB/mW. Devices with a higher sound pressure level are generally louder when supplied with any given audio source.
Sennheiser Momentum True Wireless 3's sound pressure level measurement is 107dB/mW. How loud a device is can be perceived differently by different persons, so we need to have the means to get an objective measurement of sound level expressed in numerical terms.
