Has Active Noise Cancellation (Anc)

Active noise cancellation uses more advanced technology to actively counter noise. How it works, it detects and analyzes 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.
Apple AirPods Max 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.
Has Passive Noise Reduction

Passive Noise Cancellation uses well-designed ear cups to seal out environment noise. This is used for both in-ear earphones and over-ear headphones where the headphone itself will keep surrounding noise out.
The Apple AirPods Max sits tightly in place, creating an acoustic seal that reduces background noise and prevents your music from leaking out.
Lowest Frequency
Adidas RPT 02 Sol
20Hz
Apple AirPods Max ✗
Low-frequency response measures if and how well a particular audio component reproduces low audible frequencies and if it makes any changes to the signal on the way through. Adidas RPT 02 Sol's lowest frequency is at 20Hz, the lower the low-frequency response, the stronger and juicier the bass.
Highest Frequency
Adidas RPT 02 Sol
20000Hz
Apple AirPods Max ✗
High frequency response measures if and how well an audio component reproduces high audible frequencies and if it changes to the signal while at it. Adidas RPT 02 Sol's highest frequency is at 20000Hz, the higher the high-frequency response, the clearer and crispier the treble.
Sound Pressure Level
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.
Driver Unit Size
Adidas RPT 02 Sol
45mm
Apple AirPods Max 40mm
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.
Apple AirPods Max 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 it's true that, larger drivers can generate louder sound, but this does not mean that they produce better sound.
Impedance
Adidas RPT 02 Sol
32Ohms
Apple AirPods Max ✗
Defined as the device's resistance to the electromagnetic current, when electricity flows through a wire, it experiences electrical resistance that counters the flow of current. The resistance of a wire 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.
Has A Neodymium Magnet

Apple AirPods Max ✓
Neodymium magnets when used in audio devices produce a higher sensitivity and substantial sound output using less power to do so. They can help produce music at quite a high sound pressure level, SPL, with the use of high magnetic flux. The Apple AirPods Max have this type of magnet.
