Has Active Noise Cancellation (Noise Control)
Sennheiser CX 500BT
✓
JBL Endurance Peak 2 ✗
Active noise cancellation utilises advanced technology to actively counter noise. How it works, it studies the sound pattern outside and inside the earbud and after inverts the soundwaves to counter it. Simply put, it's like taking +1 (noise) then adding -1 (counter sound by the device) to make zero which results in a reduced level of noise.
Sennheiser CX 500BT have Active Noise Cancellation enabling you to listen at lower levels of volume, causing less ear fatigue since you don't need to crank up the earbuds volume to overcome background sounds.
Has Passive Noise Reduction
Sennheiser CX 500BT
✓
JBL Endurance Peak 2 ✓
JBL Endurance Peak 2 stay well in place, this creates an acoustic covering that tones down your environment sounds and also prevents the device music from leaking out .
Both of these devices have passive noise reduction this implies that they tone down ambient noise instead of actively using ANC to cancel it out.
Driver Unit Size
Sennheiser CX 500BT
✗
JBL Endurance Peak 2 10mm
JBL Endurance Peak 2 have a unit size of 10mm in diameter, bigger drivers are more powerful, therefor producing better bass.
A driver unit is basically a mini speaker that produces sound in the device, its size dictates the sound made by the earbuds.
Lowest Frequency
Sennheiser CX 500BT
5Hz
JBL Endurance Peak 2 20Hz
JBL Endurance Peak 2's lowest frequency is at 20Hz, low-frequency response measures if and how well a particular audio component produces low frequencies that can be heard, and if it alters the signal on its way through.
Sennheiser CX 500BT's lowest frequency is at 5Hz, this implies that
Sennheiser CX 500BT make sound with a juicier bass than the JBL Endurance Peak 2
Highest Frequency
Sennheiser CX 500BT
21000Hz
JBL Endurance Peak 2 20000Hz
The JBL Endurance Peak 2's highest frequency is at 20000Hz, high-frequency response measures if and how well a particular audio device makes high human frequencies and if it adjustments to the signal while at it.
Sennheiser CX 500BT's highest frequency is at 21000Hz, this implies that
Sennheiser CX 500BT can produce a clearer and crispier treble than the JBL Endurance Peak 2
Sound Pressure Level
Sennheiser CX 500BT
94dB/mW
JBL Endurance Peak 2 93dB/mW
SPL, is the pressure level of sound, in decibels, dB, JBL Endurance Peak 2's measurement is 93dB/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 considered differently by different people, so we need to have a way of getting a standard measurement of sound level expressed in numerical terms.
