In my experience, in a recycling company (hand cutting), the hearing protection contributes to a small Eingewöhungszeit very well to pleasant (including safety glasses). The noise (29dB EU standard) I feel very good. In digital radio does not is a digital radio within the meaning of DAB +, but it's an FM radio (stereo) with digital frequency display (AM / FM). Since I work mostly on the tape FM reception is not good to very good (MW I use not) the change of location may cause harmful interference. Through its four buttons plus knob to the radio while carrying is easy to use. Some users believe that the maximum volume (82dB) is too low, I feel more appropriate than the volume too low - one should not forget that it is this is a hearing protection and not a "disco equipment". It is also possible to connect an external device (eg MP3 player) to the 3.5mm "jack input" with the hearing protection. When connecting an MP3 player, the radio must be turned off, otherwise you radio and mp3 listening simultaneously, the volume of MP3 is controlled by the player here too the hearing protection allows a maximum noise level of 82dB. Those who do not like to depend any cable around the neck can connect the MP3 player using a mobile FM transmitter with the hearing protection is only reasonable in a stationary work (this option I myself have not tried).
Hearing protection I can, in my experience, fully recommend.
