Has Active Noise Cancellation (Noise Control)
Sennheiser Momentum True Wireless 3
✓
JLab Go Air ✗
ANC utilises advanced kind of tech to actively cancel noise. How it works, it detects and analyzes the sound pattern of incoming noise and then generates a mirror signal to cancel it out. Simply put, it's like having +1 (sound from your surrounding) and adding -1 (counter sound by the device) to make zero hence "diluting" the noise.
Sennheiser Momentum True Wireless 3 have Active Noise Cancellation 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 outcompete background sounds.
Has Passive Noise Reduction
Sennheiser Momentum True Wireless 3
✓
JLab Go Air ✓
The JLab Go Air stay well in place, creating an acoustic seal that reduces background noise while preventing the earbuds sound from leaking out at the same.
Both of these devices have passive noise reduction this means that they reduce ambient noise without using technology to cancel it out.
Driver Unit Size
Sennheiser Momentum True Wireless 3
7mm
JLab Go Air 8mm
The JLab Go Air driver unit is 8mm in diameter, bigger drivers are more powerful, therefor producing better bass.
A driver unit is basically a mini speaker that produces sound in the earbuds, the unit size determines the sound produced by the device.
Sennheiser Momentum True Wireless 3 driver unit is 7mm in diameter,
which means that they have a smaller driver unit than that of JLab Go Air by 1mm
, 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 it's true that, larger drivers can generate louder sound, but this does not mean that they produce better quality sound.
Lowest Frequency
Sennheiser Momentum True Wireless 3
5Hz
JLab Go Air 20Hz
The JLab Go Air's lowest frequency is at 20Hz, low-frequency response measures if and how well a particular audio device generates low frequencies that can be heard, and if it makes any changes to the signal while at it.
Sennheiser Momentum True Wireless 3's lowest frequency is at 5Hz, this implies that
Sennheiser Momentum True Wireless 3 can produce a juicier bass than the JLab Go Air
Highest Frequency
Sennheiser Momentum True Wireless 3
21,000Hz
JLab Go Air 20,000Hz
JLab Go Air's highest frequency is at 20,000Hz, high-frequency response shows how well a particular audio component produces high recognizable frequencies and if it adjustments to the signal while at it.
Sennheiser Momentum True Wireless 3's highest frequency is at 21,000Hz, this implies that
Sennheiser Momentum True Wireless 3 can generate a clearer and crispier treble than the JLab Go Air
Sound Pressure Level
Sennheiser Momentum True Wireless 3
107dB/mW
JLab Go Air 103dB/mW
SPL, is the level of pressure of sound, measured 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 Momentum True Wireless 3's sound pressure level measurement is 107dB/mW. How loud a device is can be taken differently by different people, so we need to have a way of getting an objective measurement of sound level expressed in numerical terms.
