  1. J***i

    Great Bluetooth connection and doesn’t really compromise sound quality. Arrived in 9 days, Very impressed

  2. D***k

    Fast shipment as always. Much more comfortable than ATPX-HD BT. Can’t tell about the sound quality as it has to be burned before actual testing. Will update later.

  3. F***a

    funciona muy bien con los KZ zsn como con los zs10 pro. Bonita presentación además

  4. Shopper

    Perfect shipping, just over a week in Spain. Very good quality is perceived in materials. Interact with the smartphone by simply opening the charger cover. I knew that, with the AAC codec, I would not get maximum audio quality-type LDAC or APTX HD-I was looking for duration and comfort, to use outdoors, and Very interesting the information you get from the LEDs. Good seller, I recommend.

  5. Shopper

    muito confortáveis e leves não senti nenhuma diferença de som mas tem ruído branco nos fones e se você coloca a mão nos ouvidos para tampar os fones ele corta a conexão ( não sei se é só a minha unidade ) mas se você não coloca a conexão vai até 15m

  6. R***S

    Loved! The best you can wait! The Bluetooth is excellent, no delay in videos, has a DAC ultra powerful built-in, the sound is extremely high and clean! 10 calendar days for delivery Asia-without fee

  7. k***a

    Broken say that this ET the door or go for at least decent living bonnie yet is not living as four EE You ever know Nina with at least on the ball.
    Yet is nicer. KZ series is safe from me with gum is well and get it.

  8. C***s

    Good connectivity and an elegant presentation
    A visible and large light indicator
    I even walked away pretty far and got good connectivity
    KZ luciendose year by year

  9. A***z

    Very happy with the product. KZ has never let me down, so I acquired this new Bluetooth module. I already had the other one wearing a cable connecting both headphones which, although the sound was good, the cable behind the neck was a little awkward. With this new module this does not happen, also the sound quality remains excellent. It’s worth the purchase. KZ is quality.

  10. M***s

    Took 10 days only to get was very fast not taxed.

  11. I***i

    Makes already nice phones sound amazing. No issues with volume and great battery life. The case is nice and they simply look awesome.

  12. A***v

    Fast shipping. In call mode, very poor quality, interrupting the signal.

  13. j***r

    caja pesada, buen producto, no comprar trn son muy malos, kz lo supera

  14. G***a

    Great, but i thought they would fit my BLON earphones but sadly they dont. This Sucks..

  15. L***u

    Very good quality and it is of those products that are better than they look by image and are very comfortable.

  16. D***v

    Looks like a quality product. The case is huge).
    Connected without problems, sound on the first impressions of OK.

  17. R***v

    These modules are very convenient, light and compact. Modules have voice notifications in English. Long communication range. Modules give out a little extra noise. The microphone has a noticeable noise reduction. Well, that’s the best thing I ‘ve ever seen so far.

  18. A***t

    совместимы с наушниками zs 10 pro. звук без провода , в модуле немного хуже, но пока обрывов не наблюдал. буду тестить дальше. пока всем доволен

  19. R***a

    Found excellent has one problem fails to put the phone in the pocket, do not delay to play, top product

  20. S***n

    Fast delivery. kz as always, everything is fine. for all the time of use, never interrupted communication with the smartphone

  21. M***o

    Well made product. Connected to the phone there is no problem. The audio is good and the volume also. Maybe the microphone is a little to improve for calls. Connected instead to pc via dongle bt, sometimes feel discomfort or lost for some according to the signal, but maybe it depends on the dongle usb bt 5.0, saw that connected to the phone, not rilevo no problem.

  22. a***r

    Good product, arrived in 2 weeks in Mexico, good value and price

  23. V***a

    A box of pleasant plastic, not luftitis. The only negative, the charging port is krivovat, but it only visually strains a little, and so everyone is happy

  24. W***k

    Excellent module. made qualitatively, there are no jambs. they are small and light on the ears almost do not feel. the sound is good. i was satisfied. delivery is fast.

  25. E***s

    Ótimo produto para quem já tem os fones. 38 dias corridos. sem taxa.

  26. f***r

    muy buen módulo, quema un poco el audio pero por el precio está genial, son bastante cómodos y ligeros

  27. N***a

    Currently surprised me with the quality of workmanship and charging speed, the magnets hold the two modules are very strong and hold them with full confidence, am enjoying using the wireless headphones because is a very pleasant experience to listen to podcasts and songs service, recommended 110% for everyone.

  28. R***s

  29. S***v

    великолепное качество kz, очень доволен спасибо!!

  30. l***r

    Excellent Product, excellent quality and very beautiful. Recommend! Delivery; not taxed, delivery lasted 20 calendar days for Teresina-Pi.

  31. S***A

    Product arrived in perfect condition and works very well in my zsn pro!!

  32. A***v

    The module pleasantly surprised the possibilities. Pros: 1. do not hurt ears like from a standard KZ cable. 2. the workmanship is excellent. Work perfectly with the iPhone. The charge level is displayed in the standard widget. 3. good automatic connection. 4. long holds the charge! I checked when working in the office, I used it without removing the full time charge case for 9 hours! At the same time, only 40%! (This is not listening to non stop) disadvantages: Could not connect to the laptop and PS4. In the rest of the Not Critical: there is a minimum delay time, barely noticeable when viewing yutuba.

  33. J***o

    chegou antes do prazo tudo funcionando perfeitamente agradecido e índico para todos esse site show de bola

  34. V***a

    WOW the best purchase I ‘ve made in years, they listen very well, they look very good, everything is perfect.

  35. B***n

  38. A***o

    Excellent Product, good audio quality, works perfect with kz z10 pro

  39. I***s

    Product working perfectly and great quality.

  40. Shopper

    It works well the KZ earphone. Pairing was effortless, simple and straight forward. Wired cable or wireless with this KZ AZ09 cannot tell the different. Both sound equally good. Wireless you have the new found freedom moving your head and hand without worry of entanglement. KZ AZ09 good for outdoor or when you don’t want to have cable. Another plus point, reasonable pricing. Good quality and well made.

  41. J***y

    They have a good volume (I occupy it 35% and not 65%) and good sound quality (it depends a lot on the model of the in ear you connect it)
    Up to the hour they have a stable connection and range of the case as far as the module is concerned I haven’t heard it for more than 1 hour and according to the cell phone it has 80% to reach 3 others at 35% volume.
    The package arrived intact and sealed.
    It took almost 1 month to arrive

  42. E***n

    Very nice bluetooth module, although case not really suitable for ASX but no issue for ZS10 pro

  43. E***M

    I have a week with them and they’re great, they’re very hard on the battery. And sound quality is the same as with cables or even better

  44. I***v

    Mega gun prick, just super convenient. I highly recommend to buy!!! I’m delighted.

  45. Y***v

    The playback quality is excellent. Do not distinguish from wires. Connected to KX ZSX. Codec AAS. Quality of materials and performance at altitude ..

  46. h***r

    Exelent, I would like you to again aya discount to buy back

  47. g***r

    Arrived very quickly

  48. V***n

    It seems to work, then I’ll add a review

  49. W***e

    Fast connection & Not much loss on bluetooth. and dosen’t feel uncomfortable while wearing it and move. Charging cradle was a little big, so it’s hard to carrying inside a pants pocket. but totally satisfied.

  50. T***l

    Got the package today fast delivery good packing all items is good as described good value for money, recommended the vendor

  51. B***o

    This module is perfect! Do not delay, not noticed losses in audio quality, the connection is 100% stable is comfortable and the battery lasts as promises (5 to 6h).
    With this module MY KZ became my best true wireless!

  52. r***r

    Great thing! Everything works. Quality is fine. It’s worth taking. I have CCA c10pro headphones. everything fits. Price quality 10/10

  53. R***z

    Excelente calidad, yo había comprado anteriormente el bt de diadema aptx y la verdad no funcionó, al mes de uso empecé a tener intermitencia y a los 15 días se inflo la batería total muy mal, este se ve de buena calidad ya lo estuve probando y al menos encuentro mejor sonido que el otro adaptador y más cómodo, para los que preguntan si es compatible con el EDX les comento que no, no funciona subo fotos para que vean, lo seguiré probando y más adelante compartiré más impresiones sobre el equipo

  54. P***o

    They listen spectacular, and the best they are super light.

  55. Y***V

    Excellent quality! Very satisfied! Recommend! The talking microphone is also quite demolished. While everything works and pleases. Everything is light and firmly sits on the ears. Very convenient!

  56. A***n

    Delivered within a week. Paired with ZS10 Pro. Sounds great. So far so good.

  57. R***i

    Réception du colis impeccable, matériel de Qualité test à suivre. merci à toute l’équipe.

  58. S***z

    The quality looks very good, it was all well packaged, but I saw some rare signals from a product used in the Bluetooth receiver box, I am testing to see the sound quality and behavior of the product in Bluetooth. I’m in touch.

  59. A***v

    Looks great. The cover is large, and the headphones themselves are quite compact. The sound suits me. Delays are minimal and invisible. A great way to get TWS from wired headphones. I did not communicate with the seller. Recommend.

  60. M***s

    ! Excelente super leve você nem sente que tem atrás do seu ouvido,som perfeito.

  61. S***o

    Excellent Product highly recommended quality price

  62. R***a

    Delivery fast, 10 days to central Russia. sent fast. Everything is packed well. No damage, everything works well. The module was slightly upset by the range, in the house through two walls does not get, cheaper ears were getting. The case is comfortable, moderately heavy. In the rest, I chase, I will try to complement the review. In a couple of days I did not have time to discharge.

  63. l***l

    звук отличный, связь держат хорошо, единственное что посадочное место отличается от стандартного наушников tfz t2.
    пришлось очень колхозно обточить его ножом чтобы адаптеры налезли на разъем. доставка довольно долгая.

  64. O***a

    Excellent! Really liked, comfortable, and compact.

  65. D***a

    Fast shipping and product as it comes in description. Switch cable to these bluetooth easily and quickly.

  66. D***n

    Excellent Product, meets audio and stability in connection, are small and do not sit in the ear, very light. The box is plastic but feels premium, has a space inside that allows hearing aids to rest and not crush, being able to occupy foam eartips. Hearing aids are connected to your cell phone when you open the box, removing them is easy and quickly accommodating when you keep them. The case has a battery indicator led as well as adapters. The button to answer calls/pause and play, etc., is physical and you have to get used to it so you can squeeze it.

  67. A***n

    Fast and safe shipping. New in box item. Excellent Bluetooth sound.

  68. F***s

    Love this Bluetooth module, it works very nice with my ZSXs, audio quality is very good (Although I can notice a better quality with the cable) and signal strength is great too

  69. R***v

    The sound transmission quality is not bad, almost not to distinguish from the wire. How much they keep depends on the model of headphones, they still do not test.

  70. J***a

    Delivery has been very fast the seller is excellent the modules sound very but very well no difference to using boussard cable the codec to do is good enough

  71. R***v

    Delivery ten days intact. Everything works fine. I recommend to buy.

  72. S***o

    That wonderful product, using in my ZSX and is only joy!

  73. L***z

    I was a bit concerned about possible discomfort, but they are just perfect and sound like thunders in your ears. I have medium size ears and each module rests almost imperceptibly behind your ears. I’m using them mostly with the KZ ZSN Pro and they kick ass. You sacrifice sound quality marginally for portability and convenience. At almost 15 dollars, they are a no-brainer for any IEM user.

  74. E***v

    They look good, they sit behind the ear comfortably. Length of the earhook, I would say optimal, as when planting them especially and not visible, while it is convenient to press the button to pause/answer the call.
    Through the wall works without problems.
    The microphone is bad, they do not hear me in a noisy place. I would like better noise reduction when talking. So, forget about him.
    When connecting/off/losing Bluetooth signal/calls-there are their voice alerts, which is convenient.
    Keep the charge for a long time. From morning to evening I listen to music and by evening to stay 80%. So you can not carry the case with you.
    We went to Ukraine for about 20 days. We arrived one day before the specified time limit.

  75. Y***N

    Excelente produto! Ficou perfeito no kz zsx! Recomendo!

  76. f***t

    Envío perfecto.
    La conexión bluetooth parece poco estable, seguiremos probando.

  77. P***z

    Super comfortable, battery life approximately 8 hours at a high volume. The connection is stable at all times until there are sudden movements

  78. A***v

    All good. The first impression of this product is positive. I listen together with KZ zsn pro. The case is certainly huge, even if compared with KZ S2. There are certainly minuses. Sometimes the signal is lost for a fraction of a second, white noise is heard clearly at low volume, on pauses and when watching movies and videos on YouTube. Again I compare with KZ S2. Meditation in these modules will not listen. The shape factor of the temples is very convenient. I think for the gym or jogging it is better not to find. Personally, I have KZ S2 fall out of my ears, and the replacement of the ear cups does not save. And with these things, all the rules. By the sound personally it seemed to me that all the same there is a difference from the wire. If you compare with KZ S2 and this, the first play a little dirty. Personally, I’m happy, I like the sound of zsn pro and have the opportunity to make them Wireless. I will test further, then I will complement the review. Good luck to all.

  79. Y***n

    Delivered quickly. Packing is intact. The quality is excellent! In the ears sits well, do not strain. The sound is excellent! Very comfortable. Recommend.

  80. a***r

    Not taxed and product arrived in excellent condition.

  81. J***o

    Excellent, surprised me by quality, fitting and connection. Recommend to everyone. Using with the KZ zsn pro, was perfect.

  82. n***r

    this product is amazing in build quality! it is very aestheticly pleasing, and functions as it should.
    there does happen to be a little white noise when no music is playing but aside from that and the poorly recorded and unnecessary startup voice, these sound great. the large bar light on the case is very clean and I like it a lot, however I do wish that the little blue lights on the individual units themselves would stop blinking once the headphones are in operation. my KZ ZSN PROS fit perfectly within the case and with a nice foam cushion, but I do wish that some of that foam or a rubber had been used on the underside of the lid because some rattling dose occur between it and the headphones when stored in a pocket.
    in short I really like this product but would love to see a revised model of it in the future :))

  83. Shopper

    Excellent headphone update. Much more convenient than the previous module, which was essentially wired. The connection is super.

  84. A***v

    Came in 18 days, charged. Includes a Type-C wire. The box was intact and not crumpled.

    + Type-C
    + Powerful magnet on the lid. Rest assured, you will never open)
    + Beautiful charge indicator.
    + Quickly connect to the phone
    + It is convenient to hold on your ears. True, I wear glasses and I’m a little uncomfortable.
    + Very good sound. Almost like a wire.
    + There are almost no delays, the sound is not interrupted.

    -Case. Beautiful, but there is a sense of unreliable plastic. Therefore, be careful when wearing, may not survive the fall (but this is not accurate, did not drop).
    -When you put the headphones in the case, the headphones do not turn off themselves, before it you need to press the button to turn off.
    -The lid is not credible. Oh, I smell, not for long the Hinge will last. If the hands are straight, you can not worry.
    -The case is not small, you just do not remove it in your pocket. Although for me it is not such a big minus.

    In general, the first look at the module is positive. Especially for 1.5 k rubles.
    I hope it will serve as faith and truth)

  85. C***s

    Very good material, they listen well and the battery lasts for about 4 days, so I ordered them again, they are comfortable and can be carried anywhere.

  86. J***z

    This is easily one of my best purchases of this year. Wireless connection establishes very quickly, no fuss, and it sounds just as good as its wired counterpart. Case charging is easy and the LED indicators are very helpful. The unit itself is light on the ears and not noticeable at all. Love this product, I highly recommend! Shipping was also quicker than anticipated which is great. Love this seller, would buy again

  87. C***r

    el pedido tardó 15 días en llegar, excelente Calidad de sonido y construcción, la conexión Bluetooth es muy estable.

  88. J***a

    Very good! Found that feel lack of use in MY KZ ZSX Terminator, but see that will lower lack now with this module. The sound looks even better with more serious… Bought 2021-06-23 18:26 and arrived 26-07-2021 16:20

  89. V***o

    The thing is cool and comfortable. The sound is chic as on the wires. In games, the delay is 2-3 seconds. For music and calls-a thing! Recommend.

  91. p***h

    на проводе конечно же лучше качество, но для тех кому мало громкости эта штучка может оглушить) прерывания и фризы присутствуют… в целом я доволен, рекомендую…

  92. J***z

    The module arrived in time and shape, the quality is very good, it is a good option to avoid using cables

  93. V***a

    Ótimo custo-benefício.

  94. v***g

    13.07-paid, 29.07-received, delivery free.
    Packed in a black bag with one layer of navel. Inside plastic ложемент, with sufficient space around to protect itself. (I have only a little angles смялись) if to take for gift, then ask for a pack получше.
    Included is a wire (typec) and quite detailed instruction in English.
    The sound quality does not fall critical, compared to the wire. There is a very quiet noise on the pause, calm and uniform, does not bother. A few seconds later.
    Transmission delay, felt about 0.5 seconds.
    On the ears sits very well, even in comparison with the wire, the Burr is very comfortable. The module itself is felt only if you actively shake your head from side to side.
    The case is very large (in the photo-medium pack of cigarettes), immediately think about where you will put it.

    I took myself, for work and a bicycle, so that the wire did not interfere. As a second “Wire”-definitely worth your money.

  95. L***n

    I received the goods promptly, but the headphones have not yet arrived, so I’ll add a review later.

  96. A***w

    OK, basically. But for some reason the module came in a slightly rubbed package, and on the lid there were also small rubs. This is upsetting.
    The modules themselves, in principle, are not bad. With KZ zsn pro sound good. But against the background, noise is heard, and the system sounds of the modules themselves are too loud (probably worth using headphones with them with less sensitivity). Communication with the phone keeps perfectly, autonomy, even in game mode, very pleased.

  97. P***s

    É um ótimo produto! Boa autonomia de bateria, baixo atraso no som, mesmo não possuindo AptX. Produto recomendado!

  98. A***o

    Excellent Product estimated arrive early, sound quality very accurate and battery lasts quite worth investing, this company is congratulated by products coming manufacturing

  99. C***r

    Perfect, sound much better q the traditional Bluetooth with cable, I loved them.

  100. I***v

    At first I turned on and I was terrible about the quality of the connection, then I put it to charge and everything worked out as it should. A couple of days I use and am very pleased. The interlocutors hear perfectly
