Порадовала быстрая доставка курьером- пришли в Воронеж менее, чем за неделю. Звук средний, мягкие крючки, держатся неплохо. Из недостатков могу отметить то, что временами звук проваливается куда-то и излишне выпирают. За такие деньги неплохо, на ближайшее время пойдёт.

Хорошие наушники, доставка в мск феноменальная, прибыли через день после заказа, курьером до двери, звук отличный, но очень громкий даже на минимуме, немного непривычно, bluetooth практически не разъединяется, пришли в коробочке с сумочкой, черно-красной, правда, но всё равно отлично, в наборе 2 пары амбишур и usb-кабель для зарядки, коротенький, эдакий трэвел вариант, заказом довольна, буду брать.
