  8. R***a

    Arrived in less than a month, without additional charge the mails

  9. Y***v

    Went to saratov for 2 weeks, their price is justified.

  10. I***v

    Sent quickly, beautiful packaging, good cable included, the sound is strongly dominated by high frequencies, equalized equalizer, the complete ear pads are quite tough and could not pick up anything from them, i took the soft usual from the old senhaisers, came up and sit in my ears perfectly. In general, the headphones are very good for their money.

  11. L***a

    Arrived quickly and in good condition, i hope to place another order again soon

  12. E***v

    Do not listen to those fools who say that the headphones are shit and bass little bass here just listen to the nut And most importantly, if you came here for hi-fi then you are at True one minus i took the kit with additional wire and it is not original but it does not matter

  14. K***y
