A breakdown of the review per specifications

Design

Ingress Protection (Ip) Rating

Audio Technica ATH TWX9 IPX4
Sennheiser Momentum True Wireless 3 IPX4

Ingress protection ratings refer to the rank of protection offered by a casing, against dust and water. The letters 'IP' are followed by two values The first value of the IP rating represents protection against solids say dust, while the second refers to resistance against liquids (sweat).

Scoring IPX4, the Audio Technica ATH TWX9's rating for solids indicates that no data available to specify a protection rating, and of liquids that they can withstand low pressure spray similar to that of a shower head when tilted at 180° for 10 minutes.

In comparison to the Audio Technica ATH TWX9, Sennheiser Momentum True Wireless 3 have a rating of IPX4 meaning that we are not yet certain of their rating with solids (dust) and that of liquids is that, they both have the same rating against liquids

Weight

Audio Technica ATH TWX9 10.8g
Sennheiser Momentum True Wireless 3 10.6g

Audio Technica ATH TWX9 have a weight of 10.8g . We consider a lower weight better because lighter devices are more comfortable to move with.

The Sennheiser Momentum True Wireless 3, at 10.6g weigh less than the Audio Technica ATH TWX9 with a difference -0.2g

Has No Wires Or Cables

Audio Technica ATH TWX9
Sennheiser Momentum True Wireless 3

For a device to be true wireless it must have no wires linking any part of the device together, Audio Technica ATH TWX9 are true wireless for this matter since they don't have wires. This is an important difference as some wireless earbuds have wires linking the 2 earbuds .

Sennheiser Momentum True Wireless 3 also is true wireless since it doesn't have wires linking the two earbuds together.

Sweat Resistance

Audio Technica ATH TWX9

Sound Quality

Has Active Noise Cancellation (Noise Control)

Audio Technica ATH TWX9
Sennheiser Momentum True Wireless 3

Active noise cancellation uses more advanced technology to actively counter noise. 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) then adding -1 (inverted noise) to make 0 resulting in a reduced level of noise.

Audio Technica ATH TWX9 have ANC 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 noise.

The Sennheiser Momentum True Wireless 3 too have Active Noise Cancellation making either of the devices ideal for plane rides and morning travels. Each work with different noise cancellation types, pick the setting that suits your travel or that enhances your chill time.

Has Passive Noise Reduction

Audio Technica ATH TWX9
Sennheiser Momentum True Wireless 3

The Audio Technica ATH TWX9 stay tightly in place, this creates an acoustic covering that tones down your environment sounds well as preventing the device sound from leaking out .

Both of these devices have passive noise reduction this means that they tone down ambient noise instead of actively using ANC to cancel it out.

Driver Unit Size

Audio Technica ATH TWX9 5.8mm
Sennheiser Momentum True Wireless 3 7mm

The Audio Technica ATH TWX9 driver unit is 5.8mm in diameter, the bigger the unit the more powerful, and can produce better bass. The driver unit is basically a mini speaker that makes sound in the earbuds, the unit size determines the loudness of the earbuds.

Sennheiser Momentum True Wireless 3 driver unit is 7mm in diameter, making them have a larger driver unit than that of Audio Technica ATH TWX9 by 1.2mm , as many tend to believe 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 are capable of generating louder sound, but this does not indicate that they produce better quality sound.

Lowest Frequency

Audio Technica ATH TWX9 20Hz
Sennheiser Momentum True Wireless 3 5Hz

The Audio Technica ATH TWX9'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 alters 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 make sound with a juicier bass than the Audio Technica ATH TWX9

Highest Frequency

Audio Technica ATH TWX9 40000Hz
Sennheiser Momentum True Wireless 3 21000Hz

Audio Technica ATH TWX9's highest frequency is at 40000Hz, high-frequency response shows how well a particular audio component generates high recognizable frequencies and if it changes to the signal on its way through.

Sennheiser Momentum True Wireless 3's highest frequency is at 21000Hz, this implies that Audio Technica ATH TWX9 can generate a clearer and crispier treble than the Sennheiser Momentum True Wireless 3

Sound Pressure Level

Audio Technica ATH TWX9 102dB/mW
Sennheiser Momentum True Wireless 3 107dB/mW

The sound pressure level, is the level of pressure of sound, measured in decibels, dB, Audio Technica ATH TWX9's measurement is 102dB/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 perceived differently by separate persons, so we need to have the means to get a standard measurement of sound level expressed in numerical terms.
