Has Active Noise Cancellation (Noise Control)
Audio Technica ATH CKS50TW
✓
Sennheiser CX 500BT ✓
Active noise cancellation utilises more advanced kind of tech to actively counter noise. How it works, it listens to the sound pattern outside and inside the earbud and after generates a mirror signal to counter it. In simple terms, it's like having +1 (sound from your surrounding) then adding -1 (inverted noise) to make zero thus "diluting" the noise.
The Audio Technica ATH CKS50TW have Active Noise Cancellation allowing you to listen at lower volume levels, causing less ear fatigue since you don't have to crank up the earbuds volume to overcome background noise.
Sennheiser CX 500BT too have ANC making both devices ideal for flights and rush hour commutes. The Audio Technica ATH CKS50TW and Sennheiser CX 500BT work with different noise cancellation modes, pick the setting that you prefer for commute or that suites your relaxation time.
Has Passive Noise Reduction
Audio Technica ATH CKS50TW
✓
Sennheiser CX 500BT ✓
Audio Technica ATH CKS50TW stay well in place, creating a sound seal that tones down background noise well as preventing the device music from leaking out at the same.
Both of these devices have passive noise reduction this means that both reduce ambient noise instead of actively using ANC to cancel it out.
Driver Unit Size
Audio Technica ATH CKS50TW
9mm
Sennheiser CX 500BT ✗
Audio Technica ATH CKS50TW have a unit size of 9mm in diameter, the bigger the unit the more powerful, and can produce better bass.
A driver unit is basically a mini speaker that produces sound in the device, the unit size corellates with the sound made by the device.
Lowest Frequency
Audio Technica ATH CKS50TW
5hz
Sennheiser CX 500BT 5hz
Audio Technica ATH CKS50TW's lowest frequency is at 5Hz, low-frequency response inidcates how well an audio component produces low audible frequencies and if it alters the signal while at it.
Sennheiser CX 500BT's lowest frequency is at 5Hz, this implies that
both devices can make sound with equal bass
Highest Frequency
Audio Technica ATH CKS50TW
20,000hz
Sennheiser CX 500BT 21,000hz
The Audio Technica ATH CKS50TW's highest frequency is at 20,000Hz, high-frequency response shows how well an audio component produces high audible frequencies and if it makes any adjustments to the signal on its way through.
Sennheiser CX 500BT's highest frequency is at 21,000Hz, this implies that
Sennheiser CX 500BT produce a clearer and crispier treble than the Audio Technica ATH CKS50TW
Sound Pressure Level
Audio Technica ATH CKS50TW
110db/mw
Sennheiser CX 500BT 94db/mw
The sound pressure level, is the pressure level of sound, in decibels, dB, Audio Technica ATH CKS50TW's measurement is 110dB/mW. Devices with a higher sound pressure level are generally louder when supplied with any given audio source.
Sennheiser CX 500BT's sound pressure level measurement is 94dB/mW. The sound pressure level, something is can be perceived differently by different people, so we need to have the means to get an objective measurement of sound level expressed in numerical terms.
