Additional Information

1 x Headphones
1 x Cheholchik (seemingly imitation leather, smells a little, but very weak, and the cheholchik is chained with springy wire)
2 x interchangeable rubber plugs (there are three of them - small medium ones and more, for different ears, respectively)
Test Drive:
I put the headphones in my ears and there is no unpleasantrustling as it happens in cheap headphones. Now I “stick” the headphones into the player, turn on the player and ... There is a lot of high frequencies, but there is almost no bass ((((I took these headphones because the manufacturer (probably original) promised good bass, but this did not happen. I had to give headset wife. And how well it all began ...
Very nice and high-quality packaged, but the bass is almost absent.
More such I will not order.
