As usual delivery times are met and fast .. I had heard that this helmet was heavy but I do not think it is at this point ... in fact it is above the arch of solid rubber that weighs a ton, one wonders why Koss has designed a hoop as heavy. The sound is good and quite dynamic but I do not have enough perspective to be able to give my analysis ... By cons it has avoided for mobile use because it impedance is too high and it will deplete your smartphone or other MP3 player
What irritates me most is that obviously the product delivered is not new .... in fact when we found hair stuck in the helmet headband that means he has been on the head of someone else before so I love that Amazon says when the material has already been used instead to indicate "new equipment" on his website !!! I find it a bit limited ....
