Has Active Noise Cancellation (Noise Control)
Sennheiser CX 500BT
✓
JLab Go Air ✗
ANC uses more advanced kind of tech to actively cancel noise. ANC works when, it listens to the sound pattern outside and inside the earbud and then inverts the soundwaves to counter it. Simply put, it's like having +1 (noise) then adding -1 (inverted noise) giving 0 which results in a reduced level of noise.
The Sennheiser CX 500BT have Active Noise Cancellation enabling you to listen at lower levels of volume, good for your ears as you don't have to crank up the earbuds volume to outcompete background noise.
Has Passive Noise Reduction

✓
JLab Go Air ✓
The JLab Go Air stay well in place, creating a sound covering that reduces background sounds and also prevents the earbuds voice audio from leaking out .
Both of these devices have passive noise reduction which means that they reduce ambient noise instead of actively using technology to cancel it out.
Driver Unit Size
Sennheiser CX 500BT
✗
JLab Go Air 8mm
JLab Go Air driver unit is 8mm in diameter, the bigger the unit the more powerful, and can produce better bass.
A driver unit is the component that makes sound in the device, its size dictates the loudness of the earbuds.
Lowest Frequency
Sennheiser CX 500BT
5hz
JLab Go Air 20hz
JLab Go Air's lowest frequency is at 20Hz, low-frequency response inidcates how well an audio device generates low frequencies that can be heard, and if it makes any changes to the signal while at it.
Sennheiser CX 500BT's lowest frequency is at 5Hz, this implies that
Sennheiser CX 500BT can produce a juicier bass than the JLab Go Air
Highest Frequency
Sennheiser CX 500BT
21,000hz
JLab Go Air 20,000hz
The JLab Go Air's highest frequency is at 20,000Hz, high-frequency response indicates how well an audio device generates high human frequencies and if it makes any changes to the signal on its way through.
Sennheiser CX 500BT's highest frequency is at 21,000Hz, this implies that
Sennheiser CX 500BT generate a clearer and crispier treble than the JLab Go Air
Sound Pressure Level
Sennheiser CX 500BT
94db/mw
JLab Go Air 103db/mw
The sound pressure level, is the pressure level of sound, in decibels, dB, JLab Go Air's measurement is 103dB/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, a device 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.
Has A Neodymium Magnet

✗
JLab Go Air ✓
The JLab Go Air have neodymium magnets, if used in earbuds produce a higher sensitivity and substantial sound output while using less power. They can help generate music at quite a high SPL, using high magnetic flux.
