  1. I***a

    Reasonable price. Fast shipping and delivery. Everything works as expected. I recommend this seller.


  2. Shopper

    Compact beautiful device. Not a very good photo turned out with a beautiful blue backlight. Quickly caught the headphones. On a three-storey house I go everywhere the signal does not change qualitatively!


  3. O***K

    It’s fine. AptX, aptX HD in stock. When the first connection of a pair of headphones, the second headphones were connected for a long time, subsequent times quickly. Between optics and aux switching by Button. If the device is not used, it turns off itself.


  4. A***y

    Cool thing! Everything works fine!


  5. v***n

    Guys W Super 1) the sound quality does not change at 70 meters from the house (Cottage), at all barriers for the signal wave. 2) headphones pair works. 3) the volume increases on the device even if the Eels are quiet. 4) delivery is very fast from China surprised, the seller is sociable. Recommend MEP


  6. Shopper

    Good product indeed with very detailed and helpful manual.


  7. V***v

    Perfect machine, the sound is not changed for the worse, connected via optical, aptX supported. Recommend.


  8. j***z

    Todo correct meets its function,, fast shipping


  9. S***v

    Goods arrived. Works, but I ask a good package. normal packaging plastic film in this case all wrinkled. Damn even simple cable for 100 rubles pack lutshe.


  10. j***n

    Configuration : Tx,
    1) tried optical output of my Pioneer AV amplifier on which my fiber tv box is connected, Output : Dolby digital…No success, no sound in the connected/paired/recognized earphones.
    2) Tried optical output of the tv box, still Dolby digital plus, Still nothing…
    3) Forced the tv box to output a stereo signal and now it works ! the (small) issue is that when i want to get the sound on my amplifier it is PCM stereo and i loose the cinema effects unless i change the settings again and loose the earphones…
    Otherwise all is ok


  11. I***v

    Not fully understand the functions, but the phone connected to the amps for a few seconds, quality excellent, the background is not observed.


  12. S***o

  16. G***o

  17. N***i

    Found at this shop had arranged flash sale. Quick response and Super Fast delivery(11 days to my place). Packed the item in safety bag. The box was not damage much. The product have complete equipment and used normally. The signal distance and clarity depends on the obstacles. Recommend seller.


  18. P***v

    Everything works, the quality is at the level. Recommend!


  19. V***t

    Very good product, good quality sound, very little latency when used with TV (optical output) + 2 Bluetooth headphones. Be careful, the case does not recognize the Dolby, you have to set the sound output on Stereo. Perfectly suited to my need. Fast delivery. I recommend!


  20. A***y

    Works perfectly, but there may be problems with the quality of the optical cable because of this, there may be clicks, polishing the ends is solved.


  21. D***r

    Very fast shipping, works well for my use as a BT reciever and in bypass mode, haven’t been able to make it work with optical input/aux output even though instructions show this as an option. Loud beep on changing modes is a bit annoying but otherwise happy.


  22. E***s

    Beautiful and easy to use and very practical. Only missed one application.


  23. J***z

    The product is according to the description and has a right design. Good salesman.

  26. g***e

    Works great
    Thank you seller


  27. Shopper

    Everything is kind of honest… when transferring from a computer through a penny whistle turns on aptX


  28. J***A

    Very fast delivery.
    Quality sound. I use it to listen to TV. If I use the headphone jack on the TV I can regulate the sound and but with the optical salda I can’t regulate it. Matching the first headphones very simple but the seconds cost a little. Once paired they always connect themselves happy with purchase and seller.
    All right.


  29. D***k

    high quality sound, easy to connect


  30. V***v

    Bought for headphones to watch the TV, but the headphones need more assistant and with volume control on them, or you constantly need to adjust the volume. Other functionality works, but also need to be suitable to switch manually, every button is not less than 2 seconds to press. The app would come up with.


  31. A***n

    The order came to Norilsk quickly enough-in two weeks, everything is whole, well packed. The devices haven’t checked yet.
