Sound quality

1.lowest frequency

18Hz

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
Sennheiser OCX 685i
Sennheiser PMX 686 Sports
The device sits tightly in place, creating an acoustic seal which reduces background noise and prevents your music from leaking out.
4.sound pressure level

120dB/mW

120dB/mW

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

16 Ohms

30 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.

Connectivity

1.Can be used wirelessly
