1Hz

3.has sound isolation/passive noise reduction
Koss il200k
Sennheiser HD 4.40 BT

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

100dB/mW

113dB/mW

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

Best
