Has Active Noise Cancellation (Anc)
Audio Technica ATH ANC900BT
✓
Adidas RPT 02 Sol ✗
Active noise cancellation uses more advanced technology to actively counter noise. How it works, it listens to the sound pattern outside and inside the earbud and then generates a mirror signal to cancel it out. In simple terms, it's like taking +1 outside (noise from your surrounding) and adding -1 inside (counter sound within the device) to make 0 resulting in a reduced level of noise.
Audio Technica ATH ANC900BT allow you to listen at lower volume levels, causing less ear fatigue as you don't have to crank up the volume to overcome background noise.
Lowest Frequency
Audio Technica ATH ANC900BT
5Hz
Adidas RPT 02 Sol 20Hz
Low-frequency response measures if and how well an audio device reproduces low audible frequencies and if it makes any changes to the signal while at it. Adidas RPT 02 Sol's lowest frequency is at 20Hz, the lower the low-frequency response, the stronger and juicier the bass.
Audio Technica ATH ANC900BT's lowest frequency is at 5Hz, this implies that
Adidas RPT 02 Sol got a juicier bass than the Audio Technica ATH ANC900BT
Highest Frequency
Audio Technica ATH ANC900BT
40000Hz
Adidas RPT 02 Sol 20000Hz
High frequency response measures if and how well a particular audio component reproduces high audible frequencies and if it makes any changes to the signal on the way through. Adidas RPT 02 Sol's highest frequency is at 20000Hz, the higher the high-frequency response, the clearer and crispier the treble.
Audio Technica ATH ANC900BT's highest frequency is at 40000Hz, this implies that
Audio Technica ATH ANC900BT got a clearer and crispier treble than the Adidas RPT 02 Sol
Sound Pressure Level
Audio Technica ATH ANC900BT
103dB/mW
Adidas RPT 02 Sol 105dB/mW
Sound pressure is the average variation in atmospheric pressure caused by the sound, the sound level .i.e how loud something is can be perceived differently by different people so we need to have a way of getting an objective measurement of sound level expressed in numerical terms.
The sound pressure level, SPL, is the pressure level of a sound, measured in decibels, dB, Adidas RPT 02 Sol's measurement is 105dB/mW. Devices with a higher sound pressure level are generally louder when supplied with any given audio source.
Audio Technica ATH ANC900BT's sound pressure level measurement is 103dB/mW.
Driver Unit Size
Audio Technica ATH ANC900BT
40mm
Adidas RPT 02 Sol 45mm
The driver unit is basically a mini speaker that produces sound in the device, its size dictates the loudness of the headphone. Adidas RPT 02 Sol driver unit is 45mm in diameter, bigger drivers are more powerful and can produce better bass.
Audio Technica ATH ANC900BT driver unit is 40mm in diameter,
which means that they have a smaller driver unit than that of Adidas RPT 02 Sol by 5mm
, many people have a misconception that driver units of a bigger size automatically produce better sound quality.
However, large drivers usually have difficulty reproducing high frequencies so yeah, larger drivers can generate louder sound, but this does not mean that they deliver better sound.
Impedance
Audio Technica ATH ANC900BT
35Ohms
Adidas RPT 02 Sol 32Ohms
Defined as the device's resistance to the electromagnetic current, when electricity flows through a wire, it faces electrical resistance that counters the flow of current. The resistance of a conductor is measured in ohms. Adidas RPT 02 Sol's impedance is 32Ohms, the lower the impedance, the easier it is to get higher volume and requires less power.
Audio Technica ATH ANC900BT's impedance is 35Ohms. The impedance of earbuds is the electrical resistance of the driver unit present on the inside.
