The strength of external plug-in LG G5 Hi-Fi Plus module starting experience

LG has brought us a new flagship G5 this year. It can be said to be a big product with a â€œbrain holeâ€ because it has a modular design, and there is a module called Hi-Fi Plus . The G5's sound quality can be greatly improved, this time we will experience this product.

The LG Hi-Fi Plus package is small, with a white paper box design, there are some product descriptions, model AFD-1200 , is a LG and B & O joint launch of a component, support for the international version of the G5, Korean version, the United States Editions and regional editions such as Puerto Rico do not apply.

There are some internal instructions on the back of the package. You can see the body is made in Korea.

The inside of the package is very simple, with audio modules and protective covers, microUSB to Type-C patch cords, a portable holster and instructions.

The holster is nice and has a B&O logo printed on it, but if the audio module is placed in the holster together with the protective cover, it will be tight and the size control will not be good enough.

The back of the holster is provided with a sliver that facilitates the ejection of the module, and the details are carefully designed.

Hi-Fi Plus modules and protective covers are made of plastic, with a skin-like coating on the front and a metal B&O logo on the front, while the chin on the G5 is printed on the LG.

The logo on the back tells us that this product is manufactured by LG Electronics.

Open the protective cover, you can see the module's working standard is 5V 220mA .

Here is also a comparison of the G5's original chin, you can see the volume of Hi-Fi Plus is much larger.

With the Hi-Fi Plus G5, even on the length of the fuselage, the iPhone 6s Plus, which is known for its size, is tied.

Compared to the lower interface, Hi-Fi Plus has a 3.5mm headphone jack. Others such as the speaker, USB port, and microphone are exactly the same. However, when we used Hi-Fi Plus, we found a problem. If you use a player to play music, the whole module will have obvious resonances, which will not give you a good feeling. In addition, when using Hi-Fi Plus, there will be a 3.5mm headphone jack on the top and bottom of the phone, we can choose one to listen to music, both can not be used at the same time.

There is no difference between using the method and other modules. The battery is fixed on the module, then inserted into the mobile phone and fixed by a plastic snap.

The â€œfitâ€ of Hi-Fi Plus and G5 will not feel any different in normal use. When we insert the headphone into Hi-Fi Plus, Hi-Fi mode will be automatically turned on.

Looking at the joints between the metal body and the module, there is a clear "split sensation" and the fit is not very good, but it feels slightly better than the original module.

When you use Hi-Fi Plus to listen to music, you will find that the module itself has more heat , which is similar to many Hi-Fi players, and it consumes more power .

According to LG's settings, Hi-Fi Plus can also be used by other devices. The original adapter cable can be used normally. We connect the S7 edge and Hi-Fi Plus to decode it normally with Hi-Fi Plus. However, what's more interesting is that we need to plug the headset into Hi-Fi Plus before it triggers the "switch", then the phone will normally detect the USB audio device. At this time, we can use Hi-Fi Plus like a normal decoding amp. In addition, connecting to other mobile phones requires a specific player (for example, Seashell music player) to work properly.

After inserting the headset, Hi-Fi Plus will display "Preparing Hi-Fi Wizard" (left). After inserting the headset, the USB Type-C interface on the Hi-Fi Plus cannot transfer data normally and can only be charged.

After connecting Hi-Fi Plus, G5's system settings will increase the 32-bit high-fidelity DAC this option, which can adjust the volume and balance of the left and right channels, and will automatically detect the impedance of the current inserted headphones, this program and V10 is completely In the same way, I believe users who have used it will feel more cordial. The difference is that the V10 is a mobile phone that has an ES9018K2M chip inside, and the G5 needs to change the module.

LG's Hi-Fi Plus uses the latest mobile version of the top-level DAC from ESS Technology - ES9028C2M , and vivo X6Plus, Xplay5 use ES9028Q2M is the same series of chips, parameters are also very close, the signal to noise ratio of up to 129dB , total harmonics Distortion plus noise -120dB , even if this parameter is put into the high-end walkman can be considered a "parametric stream". In addition, Hi-Fi Plus also uses the ESS-equipped ES9602C op amp.

From the standpoint of sound performance, the sound quality of Hi-Fi Plus is definitely the top level in the mobile phone. No matter if it is the sound field, analysis or low frequency elasticity, it is the leader in mobile phones. Compared with other HiFi mobile phones, it also shows itself. Advantage. Looking at the sound, Hi-Fi Plus is a type with less audio and video, and it is a route of high-resolution and partial quality. Some users may feel that this style is too flat, but this will make it have a better front-end Adaptability. This orientation also reminds us of previous generations of iPhones, and of course its sound quality is by no means comparable to the iPhone. In terms of sound, B&O's tuning does not seem to highlight the common user's favorite vocal vocals and the "secondary" frequency of the low frequency. It is more about creating a sound balance. This may be High fidelity "pursuit.

From the preliminary experience, G5's Hi-Fi Plus is undoubtedly a very playable module, it can very effectively improve the listening experience of mobile phones, can be used alone as a USB DAC for other devices also let Its playability is higher, and we will continue to share more device gameplay and experiences with you in the future. Stay tuned.
