The personal cinema system is always a trend that will not be eliminated. Since Sony launched the first serious personal headworn cinema system and stopped production and retired from the market, Heijing should be the most visible headworn cinema brand in China. Maybe Heijing is not the first team in China to start developing SONY mini OLED headworn cinema, But at least it is the first company in China to launch a headworn 3D cinema product using SONY mini OLED LCD. Since the end of 2015, it has launched Hi Mirror H1 in JD crowdfunding, which has been popular among players. Of course, the original product has also been somewhat criticized. So at the end of 2016, H2 was born, and new appearance design, new optical design, and new control scheme were crowdfunding again in JD.

The Hi Mirror h2 in this evaluation is the second generation of 3D giant screen cinema with headwear launched by Sea Whale Technology, and it is not a crowdfunding batch product, but an improved version based on the feedback of crowdfunding users, let's call it the new h2.

The new version of h2 has changed the crowdfunding batch, which has a strong sense of plastic appearance and is different from the 3D rendering in terms of workmanship and other slot points. It has improved the surface structure and eyepiece optics, and has adopted a large area of rubber paint coating, which can be said to truly reflect the level of the second-generation products.

Unpacking: Extreme details

Hi Mirror adopts the iterative replacement product line mode, and there is no obvious model identification on the outer package. However, considering that the core parts of H1 and H2 are both sony's micro oled LCD screens, H1 and H2 are theoretically the same product.

The outer package and the inner box are also coated with skin like coating. In addition to being easy to stick dust, they feel very good.

Remove the upper cover, you can see the accessories and main body. The main body of the H2 head display is wrapped in an anti-static bag.

Accessories are placed in the paper box under the Accessories logo on both sides, and the logo is UV printed.

The cartons under the Accessories logo are all packed with independent accessories with UV printing logo. In addition, there is a special note: if a single image is displayed for a long time, resulting in the residual image of the LCD screen, you will not enjoy the warranty. Of course, there is no need to complain about the harsh warranty policy here, because this is a common fault of OLED displays.

Hardware evaluation of head display part: exquisite design elements

  In fact, the whole structure of Hikvision H2 still uses the design elements of H1, but has made many breakthroughs in details, materials and coatings. It has mixed a variety of surface treatment processes such as highlight, mirror surface and skin like (rubber coating), making the overall appearance more layered.

The elastic knob of the headband still adopts the front structure, the diamond cutting appearance style, and the logo under the high gloss mirror acrylic material, which can be said that the design team has really added a lot of thought.

The front end of the head display is made of high light plastic material, giving the user the illusion of a transparent eyepiece, which is similar to the laser men's glasses of the X-Men. However, H2 did not design a light band inside, wasting a great opportunity to install X.

There are 2d and 3d switch buttons on the left side of the head display. It should be noted here that long press the 3d button is required to switch left and right 3d when connecting with a PC.

The right side is the brightness adjustment function, with single key switch and gear brightness.

The lower end of the H2 head display is the diopter adjustment and pupillary distance adjustment area. An aux3.5 stereo audio output is set. Officially, it supports the diopter adjustment of 1000 degrees. The actual test of 600 degrees is no problem.

The forehead support of H2 is made of polyester sponge. The main body of the eyepiece is fixed with the forehead support at a single point, and the angle is adjusted through the connecting arm.

For the surface sticker part, H2 abandoned the sponge design before and used the rubber material that is very skin friendly. The reduced surface sticker thickness has shortened the distance between the eyeball and the eyepiece, and basically solved the problem of blurred edges and corners of the crowdfunding batch images.

The optical part adopts a round eyepiece with upper and lower trimming, which simulates the proportion of the user's eye socket. The actual measurement is 26mm from left to right, 22mm from top to bottom, and 12 pieces of Japanese ZEON resin lenses (6 pieces on one side) are built in. Compared with H1 eyepiece, the size of eyepiece has made great progress. The eyepiece is equipped with a light sense in the middle to realize standby power-off and save energy consumption.

Handle part: shaped and cored

Different from SONY HMZ series, Hi Mirror and other domestic head mounted cinemas are mainly portable, using a control handle with its own lithium battery The system can provide local and online video playing experience.

The control handle of Hijing H2 adopts the four core ARMCortex-A7 rk3229 chip scheme. The main frequency is 1.4Ghz, the memory is 2GB, and the storage is 32GB. It supports Bluetooth 4.0 and dual band WIFI. The built-in 7000mAh lithium battery achieves 8-hour endurance.

The handle has followed the design layout of a generation, and has made great innovations in materials and interfaces. It uses three kinds of tactile materials. The surface is frosted plastic, the chamfer is high gloss plastic, and the bottom shell is rubber paint.

The silver frosted coating is still used for the operation key cap to simulate the material of aluminum alloy. The key feel is solid and the feedback is crisp. The voice keys are flat and concave to prevent blind operation and accidental touch.

The power button and indicator light are set on the edge chamfer, which complement each other with the highlight material of the edge chamfer.

The bottom cover is designed with two hollow heat dissipation holes, and the main function and parameter icons are screen printed to show the details.

The lower end of the H2 handle is equipped with a standard HDMI output interface, which can be connected to the head display part, or other display devices with HDMI input can be connected as set-top boxes.

The upper end is equipped with a TYPE-C interface and a standard USB 2.0 interface, which means that the H2 handle charging data cable can no longer be mixed with the micro USB data cable of conventional Android phones.

H2's head display and handle combination still reach the level of 3D rendering in the crowdfunding plane.

H2's TYPE-C interface supports quick charge, so the power adapter supports three output modes: 5V 3A, 9V, 2A, 12V 1.5A, to realize the charging power of the battery in different charge states.

For the HDMI expansion of the H2 head display part, an HDMI female to HDMI male+USB2.0 HD cable is included in the attachment to drive the two OLED LCD screens in the head display through the additional power supply at the USB end.

What is worth mentioning here is the customized earphone of Hikvision H2, which adopts a short line design and works with the aux3.5 stereo audio output interface of the head display part. It will not have the problem of ordinary earphone wire winding. The huge sound cavity provides excellent sound field effect.

System UI interaction: more than half of the peers

Hijing's system is based on the deeply customized whale os on the android platform, and adopts a colorful and flat design style.

The world os is mainly divided into: my app, online video, my content, app store, system settings VR， The system has a high degree of integration. The main menu is displayed at the upper end of the interface, and the subdivision options are displayed at the lower end. The system interaction is very friendly.

In the system setting part, it is worth mentioning that the color mode provides a variety of adjustment modes, and this mode directly acts on the driver board of the head display, rather than the simple Android system level. Therefore, using this setting must be connected to HIJING H2. If connected to a third-party display device, it will display: the device is not recognized.

Another setting function worth mentioning is audio output. The handle of Hikvision H2 is not equipped with analog audio output, while the digital audio output only has an hdmi interface that mixes audio and video information. Therefore, the handle of H2 supports source code output, which can be connected to other devices to achieve multi-channel output in the next era when working as a part-time set-top box.

On online content, in addition to downloading some mainstream online video apps, such as iQIYI and Tencent Video, Hijing has its own online video source, which is relatively rich in resources. The important thing is that there is no member restriction.

After actual measurement, the resources are well produced, there is no abrupt watermark advertisement, and the subtitles are well produced, and they can be played locally after caching.

MediaCenter is the default player of HiMirror, which has only one feature: it supports 3d original disc iso, which also makes HiMirror H2 the only one among all sony 1080p oled headworn theaters at present Realize the original disk 3d.

The last one is the VR function of Hijin H2. This function is a gift. A gyroscope is built into the head display. Watching panoramic video can change the perspective with the rotation of the head. However, as a head display product, Hijin's 53 degree fov is far from the 96 degree of VR equipment, so it will not have a sense of substitution. It can only be used as a dessert to experience VR functions.

Wearing experience:

The weight of HIJING H2 is only about 280g, which should be said to be relatively light among similar products.

In fact, the headset cable can be shorter. Of course, if the investment and power consumption are not considered, the Bluetooth headset will have a better wearing experience, and the appearance of the headset is not abrupt.

Since the depth of the head display of Hi Mirror h2 is not large, it will not form a fulcrum force at the face contact point. The main force points are the forehead support and head. With a weight of 280g, the pressure for long-term use is not large. It is more comfortable to use it half lying down.

Optics&Color Calibration: Just a breath away

The optics of the new version of Hi Mirror H2 has basically passed the pass line. Although the distortion is more obvious in my opinion than that of the crowdfunding batch, in return, under the condition of perfect debugging, the four corners can be free of dark corners, the four corners are basically not blurred, and the mirror edge reflection is not obvious. The overall level is much better than that of the crowdfunding batch.

Of course, each user's face shape, pupillary distance and vision are different. They have a greater tolerance for optics. For example, their own pupillary distance is relatively wide, and they found some small problems when using Hi Mirror.

Hi Mirror's FOV is relatively large. When I adjust my 600 degree diopter, the picture is smaller in theory than in reality, but it has basically occupied the entire scope of the eyepiece. This also causes the eyepiece to be very narrow in the movable range after the adjustment is complete. A little larger action will create a dark angle. Of course, for users who pursue large pictures, We are willing to pay for some minor flaws in the experience as much as possible, but in the process of use, we still need to manually adjust the head display several times after shaking.

Another problem is that the pupillary distance of Hi Mirror is still a little bit smaller for me, which may be about 3mm to the opposite side. This causes that when the pupillary distance is stretched to the maximum, the left and right can reach the level of emptiness without blurring. If you slightly adjust it to the left and right, you will find that the single eye image will be much sharper, so it is a breath away, Of course, this tone is relative to my use environment and vision conditions.

Of course, this problem can be solved by a small function, which is to adjust the size of the picture in the setting. However, this adjustment function is not based on optics, but reduces the picture output by losing the physical resolution. Of course, with the SONY 0.7 inch 1080p oled LCD screen, the loss of some physical resolution will not make much difference in the appearance, Of course, this function is limited to playback devices that support image size adjustment.

In addition, in terms of light leakage, because the rubber surface is attached to the wider wingspan around, the surrounding light shielding is very good, only the nose rest part has a little light leakage. In addition, because the thin rubber surface is applied, the distance between the eyeball and the eyepiece is shortened, so there is still fog phenomenon in the non thermal state.

In the part of picture presentation, I have to say that the performance of Heijing black position in high-definition mode is very good. At the same time, it is connected to the popcorn a500 pro to play the original disc and remux where the assassin's creed and the magical animals are. There is no color block in the dark scenes. The transition is good and the color is rich. At least in terms of picture quality adjustment, I think Heijing h3 is still doing well.

Scalability: looking forward to the next generation

The actual test connected the popcorn A500 pro. The choice of A500 pro was also due to the fact that the A500 pro has its own ESS 9018K2M DAC and earphone, which can easily drive earphones with slightly higher impedance, and the image quality of SIGMA 8758 is the best in the contemporary player chip scheme.

In the actual test, the popcorn A500 pro can drive Hijin H2, and the 2d part of the playback is no problem, but the 3d original disc still cannot achieve the 3d effect. Instead, it is played by overlapping the left and right frames before and after, similar to the fast forward effect. Therefore, Hijin H2 only supports the left and right 3d of the original disc except that the handle supports the 3d of the original disc.

In the actual test, when the desktop PC is connected to HIJING H2, H2 will normally display as an independent display, where the copy mode cannot be realized, the expansion mode is normal, and the independent display mode also displays normally. When the PC is connected, HIJING H2 needs to press and hold the 3d switch key for a long time to activate the left and right split screen mode and achieve the 3d effect.

Therefore, it is necessary to wait for the support of the next generation of products to natively recognize 3d signals and support the 3d mode of third-party devices.

summary

In general, the new version of Hijing H2 has changed the decadent state of the product after the crowdfunding. It has made obvious improvements in product workmanship, technology and optics. Optically, it has been able to keep the four corners clear, and the edge reflection is very slight. The comprehensive effect can be said to be one of the benchmarks in many domestic headworn 3D cinemas. In addition, it has its own high-definition film source, which can be said to be a necessity for home and travel, In addition, Hijing H2 has a built-in gyroscope, which can experience VR panoramic video as a small surprise. At present, Hijing H2 has completed crowdfunding in JD and has launched sales. Those who are interested can learn about it by themselves in major e-commerce.
