Foldable devices are easier to transport and take up less storage space.
6.travel bag is included
Brainwavz M2 IEM
Sennheiser PMX 685i
The device comes with its own special case or pouch, which is useful for safe transportation.

Sound quality

1.lowest frequency

20Hz

18Hz

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

20000Hz

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 PMX 685i
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 PMX 685i
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

120dB/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.

Power

1.has a rechargeable battery
Brainwavz M2 IEM
Sennheiser PMX 685i
