  1. M***h

    Super. Free gift box. Thanks.

  2. V***o

    Thank you very much to the store!! Everything is super! Really liked! :))

  3. Y***r

    Best tws in this price range, and above all expectations, the store is very nice, there was a problem with the shipping and he answered all of my requests

  4. F***n

    Well, nice and cheap

  5. V***k

    Good headphones took for 1657r sound is dry, but if you pamper with the car, it will be better. With iPhone sound better. From the ear do not fall out, but stick out strongly. Easy. the sound is not ideal but for such money fire. And also, as a gift laid a cover for wired headphones. It’s been a month. Took back December 31st after lunch. I took it as a gift for the new year for myself (you will not please yourself, no one will please)! All with the coming!

  6. E***a

    Мне прям легли и по душе и для души.

  7. I***v

    Ordinary headphones, nothing supernatural from them is not worth waiting. Very narrow range by hearing. Fall out of the ears (who has the size of an ear cup s)

  8. M***m

    Really great ergonomic design. Incredible quality for the price.

  9. Y***a

    Delivery: 3 weeks to the Novosibirsk region (Berdsk). Track code: Tracked “to the House”. Packing: regular carton packing + postal bag. Communication: once wrote requests to the store, replied quickly. Sending did not take much time. Quality: The sound is good. Ear pads really need to be changed. When removed from the ears, turn inside out and white color in general with green is not comilfo. A couple of minutes the first time I connected to iPod touch 6. There is a small problem: connects and sings sometimes one earphone. It is treated easily, by simply pressing two fingers simultaneously on both headphones in the unit with charging. But when it is repeated, it is infuriating. The green color looks cool. As a gift, they put a case with a lock for these headphones. Basically thank you.

  10. G***g

    Already ordered here earlier headphones AS12 and just delighted with them. Here I decided to buy wireless, but not lucky married. The left earpiece does not really charge and it grows quickly. Opened the dispute, the store confirmed for which Thank you very much. In general, for its price, the sound is very much nothing.

  11. J***a

    Excellent sound quality and good volume, very happy with purchase

  12. Customer

    Money well spent.

  13. J***o

  14. S***n

    Headphones come with 3 audits with two contacts, without a button and with a microUSB interface. The store put a case for the charging case as a gift. Delivery was about 20 days.

  15. M***o

    Ooh, that’s a gun, of course! Not only that they look cool, but also the sound is awesome.

  16. M***A

    Exelent, arrived long before the estimated time and in perfect condition

  17. A***t

    I took it for home. They play great. Pretty big. For my tasks, an excellent option.

  18. A***o

    Good for the price

  19. A***A

    The sound quality is very even on top-I advise. But u guys!! Is it really hard to give a description of unpacking and preparation for the first start!? Hard yes?? So-I will write that immediately and did not understand that the contacts are stupidly glued with a film, that does not allow them to end up in case you came to you not fully charged ears!! Look on the back of the film you need to remove and put back in the case then you will be happy and lights red colors on both and only then they will see each other!! Do not say thank you)) good luck to all!

  20. M***v

    Everything is wonderful, put in addition a cover for Wired, just for my zs10. Thanks KZ. Sound and quality as always wonderful

  21. G***i


  22. H***r

    Aótimo wireless good bass great battery life comes up with a hood

  23. Customer

    sound is not very accurate to the original. way too much bass also everytime you accidentally touch earphone (to fix them in the ear for ex) – it silence the music and calls google assistant/alexa average I think it is still good for the price

  24. L***a

  25. E***a
