The amplifier is excellent, the sound quality and the volume increase changes dramatically for the better, listen to one enjoyment, thank you! I recommend to all music lovers who do not want to spend, but wants to get a fairly clean and clear sound.
Ordered 19.09.19, sent 20.09.19, received 08.10.19 in the Stavropol territory. Packing: a dense cardboard box and a layer of pup, inside a branded sealed box, and in it a branded metal box-extremely reliable))). Package: The adapter itself, the USB type C-USB adapter, the hires sticker. Wire is unthin, twisted, flexible, soft-copy wire nicehck B40. By sound: stitched with firmware (headset works) according to the instructions from the Office of the site, the result: On Mi Max 3 and PC total volume increase with increased detail in the direction of analytical and purity of sound. On the body used the player jetaudio, neplayer, Onkyo, Hiby and Fiio with 4pda. I will use it with the phone when listening to MP3 at least 320 and FLAC. Pay attention! I have a tight input on the adapter for 3,5. Initially, I did not fully insert headphones and as a result, the deterioration of the sound and heating of the adapter in the area of yusb, even sinned on the fault of the adapter. And in general I recommend both the product and the seller!
The parcel came in a month, well packed, listened to the sound of this amplifier and realized that the thing is good, but not as much as it idolize below the left comments .., wow effect did not feel, the sound became slightly louder and wider in perception, but on my subjective hearing the detailing fell, the bass almost disappeared, And the high frequencies were added and honestly to say such a feed did not really suit me, I consider the plus of this small amplifier in its mobility and minimal energy consumption due to the smartphone, in addition, you can safely connect to it large headphones, otherwise, if you have good armature or hybrid headphones, I think, It will not add much to your music, although all tastes are different ..
great transparent sound, even decent(not loud) sound volume on 300ohm headphone. happy camper here. keep in mind these baby's can be upgraded with other firmware to tweak your hearing preferences. A+ so far!
Rocked my marshall major ii from honor 10 percent by 20-25. Volume now with margin. Braided wires are very weak. Let's see how long it takes. It came in a cardboard box, the amplifier itself in a metal pencil case.
On the pc makes the sound louder. Less cod at high frequencies and overall the sound is more gentle. On the mi 9 se also percussion is more voluminous. Quality is satisfied. To moldova flew in 2 weeks. Inside there is a small hi-res sticker, glued by hand.
Listened through xiaomi 3.5 noise reduction hybrid in-ear earphone.
The purchase pleased. The sound has changed for the better. It is advisable to choose the right player for this device) onkyo, poweramp, etc. Well, headphones of course. Delivered in 2 weeks to the moscow region
Good product, sound on the stock firmware nothing
It is necessary of course to sew and will be better

I use an adapter (dac) with tfz king pro headphones and google pixel 2 xl phone, end up depending on the firmware
The seller is excellent, i recommend)
Quality of materials at altitude! But the sound even on the firmware d is not very pleased. If possible-take sabaj da2! A completely different level.
P. s. on oneplus to work the device you have to constantly turn on the storage (settings \ system) and turn on during audio playback
