Sound quality

has active noise cancellation (ANC)
Sennheiser CX 300S
Sennheiser MM 70i
This type of device allows 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. Ideal for plane rides and morning commutes.
The lowest frequency at which the device produces audio. The lower the low-frequency response, the stronger and juicier the bass.
highest frequency

21000 Hz

22000 Hz

The highest frequency at which device produces audio. The higher the high-frequency response, the clearer and crispier the treble.
driver unit size

Unknown. Help us by suggesting a value. (Sennheiser MM 70i)

The driver unit is the component that produces sound in the device. Bigger drivers are more powerful and can produce better bass.
impedance

18 Ohms

16 Ohms

Impedance is the device’s electrical resistance to the current being pushed through it. The lower the impedance, the easier it is to get higher volume and requires less power.
sound pressure level

118 dB/mW

116 dB/mW

Devices with a higher sound pressure level are generally louder when supplied with any given audio source.
has a neodymium magnet
Sennheiser CX 300S
Sennheiser MM 70i
