And now the long version:
First, I have the headphones mounted together with the wraps and Velcro adhesives in the helmet. Although the helmet Extra holes for speakers has carried the cases to the speaker (off) so on that the helmet was no longer convenient to carry. At the time I had not yet connected the headset to the phone.
So to achieve again useful comfort I removed the covers of the speakers and pasted selbige into the existing recesses in the helmet. After I had installed all the interior upholstery back the next test. This time the whole thing was much more pleasant.
So now quickly retrieved my phone and plugged the jack. The result was sobering.
I was in the apartment, it was radio on low volume and I still could better listen to the radio as the music from mobile phone with fully opened volume. On the cell phone can not be, however. With standard headphones that does not happen namely.
Expanded so all that stuff back and disposed of safely. Pity for money and wasted time for multiple inputs, conversion and expansion.
