Audio Technica ATH CKS30TW Plus have stereo speakers, devices with stereo speakers deliver sound from independent channels on both left and right sides, this creates a richer sound and a better listening experience.
Both Sennheiser Momentum True Wireless 4 and Audio Technica ATH CKS30TW Plus have stereo speakers
ANC uses advanced technology to reduce ambient sounds. ANC works when, it studies the sound pattern of incoming noise and then generates a mirror signal to cancel it out. In simple terms, it's like having +1 (sound from your surrounding) and adding -1 (inverted noise) to make 0 thus "diluting" the noise.
Audio Technica ATH CKS30TW Plus have Active Noise Cancellation allowing you to listen at lower volume levels, causing less ear fatigue as you don't have to crank up the device volume to overcome background noise.

Both Sennheiser Momentum True Wireless 4, and Audio Technica ATH CKS30TW Plus have passive noise reduction this means that both reduce ambient noise without using ANC to cancel it out. The Audio Technica ATH CKS30TW Plus have a unit size of 9mm in diameter, the bigger the unit the more powerful, therefor producing better bass.
A driver unit is the component that makes sound in the earbuds, the unit size dictates the sound made by the earbuds. Sennheiser Momentum True Wireless 4 driver unit is 7mm in diameter,
which implies that they have a smaller driver unit than that of Audio Technica ATH CKS30TW Plus by 2mm
, many people have a misconception that driver units of a bigger size automatically produce better sound quality.
However, large drivers usually have difficulty producing high frequencies so yeah, larger drivers can generate louder sound, but this does not imply that they deliver better quality sound.
Audio Technica ATH CKS30TW Plus's lowest frequency is at 5Hz, low-frequency response measures if and how well a particular audio device generates low audible frequencies and if it alters the signal on its way through. Sennheiser Momentum True Wireless 4's lowest frequency is at 5Hz, this means that
both devices can produce equal bass
Audio Technica ATH CKS30TW Plus's highest frequency is at 20,000Hz, high-frequency response shows how well an audio component produces high audible frequencies and if it changes to the signal while at it. Sennheiser Momentum True Wireless 4's highest frequency is at 21,000Hz, this implies that
Sennheiser Momentum True Wireless 4 produce a clearer and crispier treble than the Audio Technica ATH CKS30TW Plus
SPL, is the pressure level of sound, in decibels, dB, Audio Technica ATH CKS30TW Plus's measurement is 110dB/mW.
Devices with a higher sound pressure level are generally louder when supplied with any given audio source. Sennheiser Momentum True Wireless 4's sound pressure level measurement is 107dB/mW. The sound pressure level, something is can be perceived differently by different persons, so we need to have the means to get a standard measurement of sound level expressed in numerical terms.
Audio Technica ATH CKS30TW Plus's battery life is 7.5 hours, these last longer than 5 hours of listening which is considered average for a single charge. A device's battery life is commonly given by the manufacturer, and with more battery hours, you get to use it for longer and have to charge the device less often. Sennheiser Momentum True Wireless 4's battery life is
equal to that of the Audio Technica ATH CKS30TW Plus
. Each time you recharge your earbuds, they get a little less listening time.
