Has Active Noise Cancellation (Noise Control)

✓
Audio Technica ATH TWX9 ✓
ANC utilises more advanced kind of tech to reduce unwanted ambient sounds. How it works, it listens to the sound pattern of incoming noise and then inverts the soundwaves to cancel it out. Simply put, it's like taking +1 (noise) then adding -1 (inverted noise) to make 0 thus "diluting" the noise.
Razer Hammerhead Pro HyperSpeed have Active Noise Cancellation allowing you to listen at lower volume levels, causing less ear fatigue since you don't need to crank up the device volume to overcome background sounds.
Audio Technica ATH TWX9 too have ANC which makes both earbuds ideal for flights and morning commutes. Each work with different noise cancellation modes, pick the noise cancellation type that suits your commute or that enhances your chill time.
Has Passive Noise Reduction
Razer Hammerhead Pro HyperSpeed
✓
Audio Technica ATH TWX9 ✓
Razer Hammerhead Pro HyperSpeed stay tightly in place, creating a sound seal that reduces background noise and also prevents the device voice audio from leaking out at the same.
Both of these devices have passive noise reduction this implies that both tone down ambient noise without using technology to cancel it out.
Driver Unit Size
Razer Hammerhead Pro HyperSpeed
10mm
Audio Technica ATH TWX9 5.8mm
The Razer Hammerhead Pro HyperSpeed have a unit size of 10mm in diameter, the bigger the unit the more powerful, therefor producing better bass.
A driver unit is basically a mini speaker that makes sound in the device, the unit size corellates with the loudness of the device.
Audio Technica ATH TWX9 driver unit is 5.8mm in diameter,
which implies that they have a smaller driver unit than that of Razer Hammerhead Pro HyperSpeed by 4.2mm
, 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 indicate that they deliver better quality sound.
Lowest Frequency
Razer Hammerhead Pro HyperSpeed
20hz
Audio Technica ATH TWX9 20hz
The Razer Hammerhead Pro HyperSpeed's lowest frequency is at 20Hz, low-frequency response measures if and how well an audio component produces low recognizable frequencies and if it alters the signal while at it.
Audio Technica ATH TWX9's lowest frequency is at 20Hz, this means that
both devices can produce equal bass
Highest Frequency
Razer Hammerhead Pro HyperSpeed
20,000hz
Audio Technica ATH TWX9 40,000hz
Razer Hammerhead Pro HyperSpeed's highest frequency is at 20,000Hz, high-frequency response shows how well a particular audio component generates high human frequencies and if it makes any changes to the signal while at it.
Audio Technica ATH TWX9's highest frequency is at 40,000Hz, this means that
Audio Technica ATH TWX9 produce a clearer and crispier treble than the Razer Hammerhead Pro HyperSpeed
Sound Pressure Level
Razer Hammerhead Pro HyperSpeed
95db/mw
Audio Technica ATH TWX9 102db/mw
The sound pressure level, is the pressure level of sound, in decibels, dB, Razer Hammerhead Pro HyperSpeed's measurement is 95dB/mW. Devices with a higher sound pressure level are generally louder when supplied with any given audio source.
Audio Technica ATH TWX9's sound pressure level measurement is 102dB/mW. How loud something is can be taken differently by separate persons, so we need to have a way of getting a standard measurement of sound level expressed in numerical terms.
