Хорошие наушники за свои деньги
24 February 2010 
Звук хороший, но нужно пробовать на свою голову.
Хороший звук, если подключить к хорошему девайсу
Уши начинают болеть после пары часов прослушивания музыки. Давит верхняя дужка
Pavel: use Koss UR21 more than year

Хорошая вещь
20 December 2011 
хорошие уши, но слушать в них рекомендуется музыку с битрейтом от 320 и больше)
качество звука отличное, вообще не "рыпят", хорошая звукоизоляция
тонкий привод, на ушную раковину действительно давит
Denis Stepa: use Koss UR21 month or more
