Has Active Noise Cancellation (Anc)

Sennheiser Momentum 4 Wireless ✓

Adidas RPT 01 ✗

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 zero hence "diluting" the noise.

Sennheiser Momentum 4 Wireless 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

Sennheiser Momentum 4 Wireless 6Hz

Adidas RPT 01 ✗

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 while at it. Sennheiser Momentum 4 Wireless's lowest frequency is at 6Hz, the lower the low-frequency response, the stronger and juicier the bass.

Highest Frequency

Sennheiser Momentum 4 Wireless 22000Hz

Adidas RPT 01 ✗

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. Sennheiser Momentum 4 Wireless's highest frequency is at 22000Hz, the higher the high-frequency response, the clearer and crispier the treble.

Sound Pressure Level

Sennheiser Momentum 4 Wireless 106dB/mW

Adidas RPT 01 ✗

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 the means to get 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, Sennheiser Momentum 4 Wireless's measurement is 106dB/mW. Devices with a higher sound pressure level are generally louder when supplied with any given audio source.

Driver Unit Size

Sennheiser Momentum 4 Wireless 42mm

Adidas RPT 01 ✗

The driver unit is basically a mini speaker that produces sound in the device, its size dictates the loudness of the headphone. Sennheiser Momentum 4 Wireless driver unit is 42mm in diameter, bigger drivers are more powerful and can produce better bass.

Impedance

Sennheiser Momentum 4 Wireless 60Ohms

Adidas RPT 01 ✗

Impedance is the device's resistance to the electromagnetic current, as electricity flows through a wire, it experiences electrical resistance that counters the flow of current. The resistance of a wire is measured in ohms. Sennheiser Momentum 4 Wireless's impedance is 60Ohms, the lower the impedance, the easier it is to get higher volume and requires less power.

Has A Neodymium Magnet

Sennheiser Momentum 4 Wireless ✓

Adidas RPT 01 ✗

Neodymium magnets if 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 Sennheiser Momentum 4 Wireless have this type of magnet.
