I bought this product to bringing in a suit, but it will be difficult and that, because of the noise that the power box is, but once you are in a place with music, noise is inaudible.
I do not know if the housing of different vendor make the same sound, so I can not compare, I took the seller because I found his presentation of well-made products and its well arranged text, which changes the other.
MAJ:
after having informed, that noise is actually a high frequency necessary to clarify and varies with the color of the thread (verified because I took one pink and one blue and the sound changes) of large person tries to drowned coil in the case in the non-conductive adhesive for soundproofing, I have not had time leaned on an amendment of this type, I already put the electrical insulation tape and noise is already weaker .
attention this frequency is audible certain person, if you wire integrated in clothing, thought to others if you are in a place without music.
thank you note of this comment if you was helpful
ps:
video I made is not terrible because the imposed maximum limit is 100 mega, so I had to act quickly, as has the inability to make a video with the webcam I used my s5.
