    el sonido que brinda es muy bueno solo tengo unos detalles que decir cuando estas escuchando música y haces una llamada con el SmartPhone el auricular derecho ya sea in ear o o over ear de tus audifonos sube bastante de volumen la primera vez que experimente eso senti que me reventava el timpano. no se si solo sea mi unidad.. Espero que si. de todo lo demas esta perfecto

  31. P***s

    product is awesome,,,. all codecs work great,, very loud also… but … never sent the leather case that I paid extra money for …. how do I get that now??

  32. AliExpress Shopper

    Shipping was fast and the product was genuine. I like the shanlng UP4 quite a lot despite some small flaws. First even if it is much more powerful than the previous model i had it is still lacking power for my AKG k 702 which are not considered as hard to drive, reviews on the wewb are missleading since they claim that it can drive anything, this is clearly not the case. Otherwise the volume knob is way better than usual push buttons but it has an infinite range so it is a bit hard to know what is the current power out put. Also while playing with the volume i often either pause the play or switch the device off. The volume button is the only that we use on such devices, i never ever pause or skip track with the device (i do it on the application that plays music). So it would be better to have a volume button just handling the volume, with a finite range and no other function.

    Anyway the sound stage is very nice and the sound quality awesome. I m happy with my purchse.

  52. AliExpress Shopper

    Fast shipping. Well packed. Great Sound. Seller and recommend!

  53. W***g

    Worked great till I downloaded the app and updated the firmware. once I updated the device could no longer be recognised over Bluetooth as a media device, only handsfree (calls only)

    Contacted the store, where they just stopped responding to me.

    Moral of the story, just buy from Amazon, it’s easier to return.

    (second time a UP4 stopped working)

  54. H***s

    Product as described

    Fast delivery, everything works, the sound is excellent. Comes with a Firmware 1.2.3.
    By Air did not update to 1.3.0, had to via Windows (Win10 need to disable driver signature check).

  62. AliExpress Shopper

    Smart device. There is only one moment-with a smartphone in USB-DAC mode does not work (with a computer all OK). Sound at the level, that’s only not very different by Bluetooth from USB (in comparison with Fiio btr5). The battery keeps much better Fiio

  63. s***o

    Shipping it faster and more like it was made, hifi Hi R5 3.5 single output than the nail.

  64. F***n

    Package arrived within 10 days! Great product. Good communication with the seller. I am very happy.

  66. O***o

    Surprise me very a device so light and so small have a amplification with this quality. Gave much difference in the quality of my Galaxy S9, because the sound plus win body, not show frequency and all sounded very well, same with my KZ ASX that has the medium pitched shrill and passed to bring more neutrality. Sensational.

  67. AliExpress Shopper

    와우! 2.5파이 3.5파이 모두 음질이 좋네요. 더불어 어플역시 한글지원이라 아주 편합니다. 케이스는 별도로 구매하지 않았는데 박스안에 있는 클립케이스를 끼니 따로 구매안해도 되겠어요. 어차피 아웃도어용으로는 블투이어폰을 쓰니 궂이 케이스는 필요없을듯.
    직관적인 인터페이스에 듀얼덱이 2.5 3.5에 다 있어 듣다보니 의외로 큐델릭스 5k보다 음색이 좋은듯 합니다. 가성비 좋네요
