- Screen size.
- Initial firmware with only a few faults.
- Gapless from the beginning.
- Battery life.
- Power.
- Peachy audio.
- A firmware with Rockbox is now available.

: The layout of the buttons is original but non also ergonomic.
- Shortage of accessories, not fifty-fifty a instance comes.

Packaging:
The packaging of the DAP is quite compact, it is only slightly larger than the thespian itself. The outer box is fabricated of cardboard, decorated with the player's paradigm on the front and with the specifications and features on the back. Inside is another box, quite robust and black. Afterwards removing the cover, you tin access the DAP, wrapped in a white semi-translucent bag. The screen is protected by a plastic protector. One time the DAP is removed, two openings can exist accessed to insert the fingers and remove the packaging. Underneath this is the USB charging cable, whose connector is USB type C, a 3.5mm male/male Jack cable, 5 adhesive tears of transparent plastic, 2 protectors of the iii.5mm Jack connections, another screen protector, the English/Chinese education manual and the warranty carte du jour.
The packaging is fair and simple.

Design, construction and other features:

The outer casing is made of aluminium alloy. All corners are rounded and the touch is pleasant. The shape and size of the X3II is reminiscent of the previous model, narrow and elongated. Otherwise information technology looks aught similar information technology. The 2.4" IPS screen is the primary protagonist of the new look of the DAP. At the lesser there are 5 buttons, with a somewhat strange distribution, two small ones on the left for the "return" and "bill of fare" functions. A central one for "play/interruption" and 2 small ones on the right for "rewind" and "forward". On the left side in that location are iii buttons, the top, in red, is the "off / on / lock", below it there are two buttons of the same size, only in color of the example, for the book. On this side is the SD card slot. On the opposite side there is nothing. On the underside, say, at the base, is the charge/USB connector, the line output and the headphone output, both 3.5mm. On the back side comes the brand but not the X3II model.

Battery

From my tests the battery seems to comply with the 13h specified. The control of the bombardment is very reliable and I have non noticed whatever jumps or anomalous notifications.

Playback

Gapless, yes, since the first firmware version. After turning on the playback continues from the indicate at which it was turned off, with the volume at which it was, but in paused mode. Later on pressing "Play" the sound starts with a adequately fast "Fade in".
There are no clicks between songs, neither at the get-go of whatever song, nor subsequently pressing buttons.

Volume Control

The volume is controlled past two side buttons and goes from 0 to 100. The maximum volume is configurable. It has low and high gain. The volume control with 100 steps is very precise and information technology is always possible to adapt it to the desired point.

Interface and usage:

The bill of fare is somewhat curious, has an initial mosaic with six "buttons", are as follows:

• Music Browser
• Music Settings
• Organization Settings
• My Music
• Bluetooth Settings
• Music Playing

Pressing inside each button will access each bill of fare:

As you can encounter, it has many options and features, it is non the subject of the following review to explain them all. It must be said that the operation is impeccable, at that place are no delays after pressing the keys. Everything works as it should, even being the first version of firmware.

I was able to test the Bluetooth with the car, the connection was fast. The reproduction was free of cuts and fluid. Yous can select the option "High Quality" to utilise the best playback quality via Bluetooth.

Audio and particular impressions

I'll kickoff, like other times, talking about the output impedance. As it could non be otherwise in a player of this category, is inferior to 1Ω.

The frequency response is quite flat from twenty to 10kHz, thereafter decays to 20Khz at a value below ii%. Co-ordinate to the specifications the frequency response is 20Hz to 20kHz ±0.5dB..

The profile of the new X3II is like to its predecessor, quite neutral throughout the range, with expert level of detail and separation, pulling to the analytical side. It's a different sound to the Fiio I've heard (X1I, X1II, X3II, X5III) and this has been the reason for me to buy it: to run away from that somewhat dark and duller profile. I had the opportunity to endeavour the xDuoo X3 a long time ago and its sound captivated me from the first listening, the awareness of clarity and openness, which I did not find in the Fiio, is what about defenseless my attending. After trying the DAC AK4490 in the Zishan Z3, I wanted the new xDuoo X3II to sound dissimilar from it, in the line of its predecessor, then I risked buying information technology. And it has been a success, everything I was looking for 100€ is there, even better.

The bass is very deep, slightly emphasized simply never colored, not a warm DAP like the Fiio X3III, but seeks neutrality rather than warmth. This does non mean that the bass take a special bespeak. Ever nether control, the X3II offers the necessary ability in this segment when required, but with very good precision, item and a remarkable resolution. Thanks to these qualities, the xDuoo is able to correspond this range, from the deepest sub-bass to the lightest bass drum, with remarkable separation, something that is not within the attain of many DAPs.

The mids are reproduced under the same premises as the lower zone, where neutrality and openness over again stand out, as well as the ability to extract details. The level of transparency and separation continues to stand up out in this stage, without the precision of the mids pregnant excess brilliance. The command and smoothness are still there to at-home any wheezing. I insist that information technology is not a warm player and those looking for this kind of signature will have to buy something else. But it'due south not that information technology has a totally aseptic sound either, because the detail is displayed accurately but smoothly.

Trebles feel the same way, very slightly softened in the frequency bend but equally all-encompassing. The maximums are fragile and subtle, clearly perceptible merely gratis of any hardness.

But, in my opinion, the strong point of this DAP is the amplitude of the sound. In my quest to widen the phase, I go upward small steps with every € I spend. And I'm sure I'll get in. And that's where I savor the near, with the separation, clarity, transparency, cleanliness and naturalness of the remarkable scene of this DAP.

Comparisons

xDuoo X3II vs xDuoo X3I

The sound of both have a very similar contour, but is the qualitative leap to sound level between them very big? Not actually. The differences exist: the onetime version has a brighter sound, but also harder, treble is a picayune sharper, a niggling out of command. While in the new version they sound softer, less hurtful, more pleasant to my ears. Bass also differ, the sub-bass extends more, there is some accent on them, more than depth and definition. Bass in the erstwhile version are drier, it doesn't feel like they go down so much giving a slight trimming awareness, although perhaps they have more than of a presence in the eye bass. As for mids, the thing is very equal, I only find some incidence in the voices of the onetime version, due to that greater brightness it has. Globally information technology could exist said that the new version is a lilliputian warmer than the onetime i.

In terms of scene the new version is ameliorate, although not for long. There is also more clarity, more space, more than air and separation. The sound in the old version is more compact and tight.

xDuoo X3II vs Shanling M0

The M0 is ane of the DAPs to crush. For its cost, size, functioning and power, it is a tough rival. In terms of size you tin non compete with information technology. In addition to having a touch screen, good battery life, has a unique ability, reaching up to 1.4V output. The profile of the M0 is reminiscent of the kickoff xDuoo X3, but is more than refined and softer. And although I think they have many similarities, the sound of the M0 is besides an evolution on this first X3.

With respect to the new X3II, the M0 has the well-nigh nowadays treble, most marked, while the xDuoo X3II has the deepest bass. In the M0 it seems that the bass is somewhat displaced, brighter, the sub-bass does not descend so much.

In terms of separation and scene the X3II is somewhat better, the details are perceived more separated, somewhat sharper. I find the X3II more precise. The scene is bigger in the X3II, every bit there is more air between the details, yous perceive more three-dimensionality in the image. The audio is also wider in the X3II.

In terms of scene and instrumental recreation, also every bit separation, I adopt the new xDuoo because I find it richer in details.

In full general, differences in sound are based on subtle details in each other'due south sound profile. But the xDuoo X3II fits more into my personal preferences.

In the same style that the M0 gains in size and touch screen, the X3II gains in power, virtually doubling the M0, which is a barbarity.

It is clear that both are excellent DAPs for their price range, the choice of i or the other will only depend on our preferences, as neither of them will be disappointed, if we assume the price they are worth.

Decision

The new iteration of xDuoo's X3 is non only a step frontward from the original wonder that was its predecessor, but it is a fully-fledged evolution that adapts to new technologies, calculation a large scattering of features capable of competing without whatever fear with the rest of the segment's DAPs. But in addition they are immune to extend quality in the audio, advancing in the same sonorous signature, calculation even more power and better duration of the battery. And all this at a round price, around 100€, a psychological barrier that, for many, already represents a serious expense for a dedicated DAP.
