Sound Signature

The XP-2 sounds very linear and transparent. It doesn’t impede the sound of music at any point, whether it’s only using a passthrough amp or is actually using its DAC for decoding purposes. That said, Bluetooth mode does introduce some mild warmth into the low-end of the sound signature, though this doesn’t affect the overall stellar dynamics that the XP-2 presents. This could be due to any number of factors but is likely the result of some decoding artifacts introduced inside the XP-2’s receiver. I am glad to report that the shift in presentation is so subtle that switching between Bluetooth and USB/Aux modes isn’t disorienting at all.

Звук

Те пользователи, которые уже сталкивались с устройствами от xDuoo, хорошо знают, что эта компания умеет делать качественный звук. Не является исключением и данный гаджет.

Бас достаточно быстрый, упругий и достоверный. Однако для любителей тёмного звучания низких частот может показаться недостаточно, поэтому придётся задействовать эквалайзер. Средние хороши: все инструменты играют на своих местах, вокал звучит, как живой. Из-за недостаточной плотности низких частот ощущается небольшое смещение спектра в сторону верхней середины. ВЧ выглядят прозрачно и естественно. Здесь нет выпячивания верха, когда тарелочки и колокольчики парят где-то на недосягаемой высоте. В итоге звуковая картина выглядит максимально реалистично и, можно так сказать, даже несколько прозаично.

В целом звучание xDuoo XP-2 можно оценить на твёрдую четвёрку по пятибалльной системе. Устройство практически не вносит эмоциональной окраски, поэтому кому-то эффект может показаться несколько блёклым. Впрочем, многие как раз оценят беспристрастную и реалистичную подачу, которую демонстрирует XP-2.

Features:

I mentioned the modes the device can be used in during the intro, but lets look at these in a bit more detail.

The simplest mode is as a wired Amplifier. In this mode, input is via the 3.5mm aux in/out port and output is via the 3.5mm Phone Jack. Xduoo advertises the amp circuit as having ± 5V rails for maximum drive which provides roughly 250mW @ 32Ω.

I found the little unit had no problem powering most headphones including the 600Ω Beyer 990 and the T50rp which are notorious power sponges. While the t50rp couldn’t be pushed to ear-splittling levels, with the gain on high, it had more than enough power for reasonable listening levels.

Most fairly sensitive IEMs and even some low impedance/high sensitivity cans will be better served by the low gain mode as high gain leaves very little usable volume control before it gets loud enough to be troublesome.

Next up, USB DAC Mode. I tested this using the iPhone 8 with a camera connection kit, an HTC m11, the Cayin N3, and the Moto Z3 Play smartphone.

The Xduoo worked effortlessly with all except the Moto which refused to detect it as a USB DAC. On the Iphone and M11, all apps worked well and the unit’s battery held up well to all day work sessions.

I was also able to connect the XP-2 to a Windows 10 PC and use it as a DAC/amp using the native win10 drivers.

It should be noted that the USB Dac mode can be combined with bluetooth headphones so the phone can be left in a pocket or so the user can walk around the office and not be tethered to the DAC.

The third mode is the bluetooth mode. In this case, we are using bluetooth between source and the XP-2 and the XP-2 is providing both DAC and amp functionality.

In this mode, the gain switch is still in play since the headphones are wired to the XP-2 and the bluetooth connection is prior to the amp stage. (When using bluetooth headphones with the XP-2, the gain switch is bypassed). In this mode I was able to again pair the laundry list of phones and PCs to the XP-2 with no issues (even the moto works this way) and connectivity was solid as long as the XP-2 and source device remained within 5-10 feet of each other.

This is nice as a few devices I have tested have suffered from cut-outs when one was in a pocket and the other not. Battery life in bluetooth mode is lessened somewhat, but it was still able to put in an entire workday (8 hours without needing a charge). (When used as a wired amp, I was able to get 2 days out of it before it cut out).

Medium Review

The xDuoo is pretty compact for a device of its form-factor. The little device packs a good amount of tech within its aluminum frame. Said frame is constructed with precision, not presenting any unwieldy seams or uneven surfaces.

While I would have preferred to see xDuoo not use such difficult-to-remove screws so I could see exactly what’s going on under-the-hood, I can understand why they wouldn’t want the average-joe tampering with a device that is designed around creating high-voltages.

The XP-2’s buttons and sliders are all made of metal, and they are fixed to the frame well. While the buttons have a minute amount of shuffle, I can accept that for a reasonably-priced device such as this.

Beside the Select button is an LED that turns different colors depending on what connectivity mode it is in. To the left of the BT Link button is another LED that acts as a Bluetooth pairing indicator.

Mobiletechtalk Review

The xDuoo XP-2 itself is constructed from a slab of metal, with the only hints of plastic are on some of the buttons, and it’s just so sleek. Due to the fact it’s 85% metal, it’s incredibly sturdy as well which bodes well for the durability of a product that’s going to be out on the road with the individual in question.

On one edge is the Bluetooth pairing button, gain switch (low to high essentially), and a mode select switch to toggle the input source between Bluetooth, USB or Line in. Moving around the device, up top there’s a 3.5mm AUX input/output as well as a 3.5mm phone output port, alongside the volume knob which feels so nice when turned. Finally, on the bottom edge is the microUSB charging port as well as a microUSB input port, with associated status LEDs.

Build Quality and Design

The Xduoo XP-2’s aluminium CNC chassis feels very robust without being heavy (it weighs just 115g). Dimensions are 10.4cm x 5.5cm x 1.5 cm which is just slightly bigger than the FiiO M6 DAP.

On the front panel are the 3.5mm headphone out, 3.5mm aux in/out and volume pot/on/off switch. The volume knob is a lightweight aluminium with knurling and has a small amount of resistance. It has an enclosure on each side making accidental movement less likely while the device is on your pocket but I would have liked to see a little more resistance on the pot.

On the rear panel there are 2 Micro-USB ports. The first is for charging only and is accompanied by a very small LED which lights up in red to indicate the unit is charging. The second USB port is for data transfer and also has a small LED next to it to indicate when the device is connected to a source via OTG.

The right side of the unit contains the rest of the controls including (from left to right): Bluetooth pairing LED indicator, Bluetooth link button, hi/low gain switch, the source type select button and source selector LED indicator.

Multi-functionality

For hardware, the xDuoo XP-2 adopts a AKM AK4452 DAC chip (that if not wrong, is newer over the one used on the X3 II player) with support up to 24bit 192kHz, and an output power of 245mW (at 32 Ohm). Decent numbers for an entry portable device at this price point, but more important are the different features this device supports. It can be used as any standard portable amplifier or as external DAC, and also work as a Bluetooth receiver. As both amplifier and USB DAC the XP-2 works without issues, whether connected to a PC or portable player (and also with those that support DAC line-out).

As for wireless usage, the XP-2 uses the new Bluetooth version 5.0. Definitely a good choice from the company, however very limited regarding codec support with only AptX, AAC and SBC, but not the higher ones like AptX HD, LDAC and such. It is a downside, especially considering that various and much smaller Bluetooth receivers can support the hi-res options. Nonetheless, the wireless connectivity is very solid, maybe thanks to the 5.0 BT applied here and the range is very decent too.

The XP-2 lacks playback controls for wireless use. The 05BL module for Bluetooth addition on the XD-05 already had the needed three playback buttons, meaning it was not something impossible to implement on this model, especially as wireless option would be a selling point here. Yes, the XP-2 packs the better battery, more power and better built over compact wireless amplifiers, but it can result annoying to use the phone or player controls instead. In the end, it may be just getting stacked along the music device, making no difference over using the traditional ‘wired’ setup.

Nobsaudiophile Review

SOUND :

OVERALL SOUND IMPRESSIONS :

With the Xduoo XP2, we have a AK dac that remind me of AK4490 dac from Xduoo X3II, but with more bass emphasis. When used as BT receiver we have a warm, weighty sound, that tend towards a smooth overall rendering. Sub bass is more emphased than mid bass, mids are quite linear, not bright, near organic sounding, treble is smooth but well layered with good tone and soft timbre.

The sound is quite energic because of weight impact, but still warmly rendered, far from being analytical, it can remind of analog type of sound, laid back but resolved and greatly enjoyable.

As well, there a sense of transparency to layers, which soundstage panoramic widness help to heard.

USB OTG DAC mode have the best sound rendering, it is clearer and more balanced than with Bluetooth. The bass have more control and details even if still slightly pushed fowards. Clarity of imaging is impressive. Details retreival are above average but not analytical, it feel natural and never cold or artificial sounding. The fact you can listen up to 192khz/24bit music files is a proof that the DAC is fully take advantage off in USB mode because there limitation to APTX 5.0 Bluetooth (48khz/24bit).

BLUETOOTH mode sound very similar, but little less agile and clear. The big difference is in bass warmness that feel less controled and stole some space in soundstage as well as clarity. Mids have little less body too, but overall sound is excellent, with a wide airy presentation and good transparency.

AMP mode is very useful and make this BT device stand appart because of this great feature. It’s quite powerful at high gain, and I think the amping section is responsible for extra bass and warmness we have with overall XP2 sound rendering, This is up to the pairing for getting excellent sound, but earbuds lover should really think about this Bt Receiver as the go to solution for enjoying full potential of earbuds on the go, XP2 is just from another league for amping earbuds, headphones or hard to drive iem.

Construcción, diseño y conectividad

Lo primero que destaca es su compacto tamaño (105x56x15mm) y su bonito cuerpo de aluminio, el cual se siente muy robusto pero no resulta pesado (115g.)

El su parte frontal encontramos una entrada para auriculares de 3,5mm, una entrada y salida de línea también de 3,5mm y la perilla de volumen, que también se usara para el encendido de la unidad con un pequeño giro hasta sentir el “click”. Sabremos que esta encendido y con batería gracias a un led situado en la parte inferior de los conectores que se iluminara.

La perilla, también realizada en aluminio, al girarla para modificar el volumen sentimos que es lineal ofreciendo una resistencia suficiente y progresiva, muy precisa y agradable al tacto. Por sus costados la perilla se encuentra cubierta para evitar un manipulado accidental cuando se encuentre dentro del bolsillo de nuestro pantalón.

En la parte posterior encontramos dos puertos micro-USB. Con el de la izquierda cargaremos la batería de la unidad y acompañado por un led de color rojo nos avisara cuando la batería este realizando dicha función. El puerto micro-USB derecho es el que usaremos para transferir datos de fuentes ya sea OTG o PC/MAC. Un led también a su lado nos indicara que se encuentra conectado.

Немного лирики

Первым моим mp3 плеером стал xDuoo X2 (До него, использовал для воспроизведения музыки телефоны. Ещё ранее, были касетники и CD). Поэтому бренд xDuoo занимает особое место, в моем сердце.

xDuoo X2 у меня был из самой первой ревизии. Той самой, где конструкция кнопок выносила мозг. Тем не менее, плеер радовал. И я нисколько не пожалел о его приобретении. Потом был куплен xDuoo X3. Но он у меня надолго не задержался. Так как в то время — я уже стал интересоваться устройствами, которые выше классом. На этом наши пути с xDuoo разошлись.

Но вот спустя несколько лет, у меня на руках опять устройство от этого бренда. И первое на что я обратил внимания, это сильно возросшее качество. Уже не возникает ощущения кустарности, или сырости продукта. Это уже не Х2 первой ревизии, собранный на коленке. Качество растёт. И это хорошо.

Что же есть ещё интересного в xDuoo XP-2 — будем разбираться ниже, в обзоре.
