3.has a detachable cable
Brainwavz M2 IEM
Sennheiser IE 4
With a detachable cable you can use alternative cables, and if the cable is pulled it will pop out instead of breaking.
4.sweat resistance
Brainwavz M2 IEM

Sound quality

1.lowest frequency

20Hz

40Hz

The lowest frequency at which the device produces audio. The lower the low-frequency response, the stronger and juicier the bass.
2.highest frequency

20000Hz

15000Hz

The highest frequency at which device produces audio. The higher the high-frequency response, the clearer and crispier the treble.
3.has passive noise reduction
Brainwavz M2 IEM
Sennheiser IE 4
The device sits tightly in place, creating an acoustic seal which reduces background noise and prevents your music from leaking out.
4.has active noise cancellation (noise control)
Brainwavz M2 IEM
Sennheiser IE 4
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.
5.sound pressure level

115dB/mW

106dB/mW

Devices with a higher sound pressure level are generally louder when supplied with any given audio source.
6.impedance

20 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.
