Kai Bor K9 PLUS 4K Blu-ray Player Reviews: 4K Theater Upgrade

As early as June 2015, when the bank ran out of deposits, sold real estate, and purchased more than one million, it reluctantly upgraded the dwelling of the 87-square-meter meter of the Royal Park to the 130+ “well-to-do house”. The price of the Royal Park is always a pain.

It is with this dwelling that, as an uncle, it is only possible to realize the dream of my home theater. Ever since, after fighting half a year with "Lazy Cancer", it has only managed to publish my original "ASUS AC5300 Single-Road Diao Duo Smart Audio and Video Home Network" in "Aunt Zhang" (what's worth buying).

It turned out that high-definition video is a bottomless pit, with 1, thinking about 2, 2 with thinking about 3. Recently, it has started LeTV's Super 4 smart TV, split soundbar, and supports 4K and HDR. The original home network topology is like this:

The playing equipment used is a small box of millet. Have to admit that Xiaomi small box of software is still good. But for large-rate 4K video, the decoding capability is a bit overstretched.

As a result, he began tossing again. I remember three years ago, I used the Q9 of Bork, a high-definition player with a built-in hard disk. During the double 11th period, I heard that the new version of the KBolle K9 PLUS has been launched. . . . . .

Saying that this hardware is still very strong. A53 processor, 2G memory, 16G EMMC. Looks like the first high-definition player on the market using Android 6.0 system. Support 4K HD decoding, support 5G wifi, and Gigabit LAN. This is what I need, Gigabit LAN port with ASUS AC5300 router Gigabit LAN port, so that from the MyCloud 3T NAS transmission of high-rate 4K high-definition movies makes sense. At the same time support 4K and HDR, but also just with my LeTV.

Double 11 logistics is a pit, arrived around the 30th.

The packaging is similar to that of the previously opened KBoer Q9.

A big "1" character is a combination of various features of the product.

This versatility is also a cloud for me. I just want to use it for better local HD playback. Of course, there is HDR.


Supports 4K, 3D, H265 decoding

Family portrait:

Host, remote control, power adapter (too big), manual, HDMI cable, and a game gift card.

Compared to Xiaomi's streamlined remote control, I still prefer the remote control with a numeric keypad.

Unfortunately, the remote control is not Bluetooth-connected, or it is perfect.

Remote control button with backlight design. This is good for home theater dark environment operation.


HDMI cable

12V/2A power adapter, to be honest, a bit big.

"I am MT2 TV Edition" experience card

This stuff is useless to me.

Open Bor K9 Plus Host: The same appearance as the open Bor Q9. Brushed metal shell, black. Front panel with LED monochrome display, with hardware key and navigation keys. Generally use the remote control, these buttons are rarely used (actually lazy).

The rear interface is still very rich.

Gigabit LAN, TF card interface, optical fiber interface, DC IN interface, composite AV-OUT interface (without wiring).

Since the 3.5-inch hard disk can be built in, active cooling is arranged.

One of the features of the KBOR PLUS K9 PLUS is the “HDMI IN” which supports HDMI source input and supports picture-in-picture and video recording to the internal HDD.

3 USB ports on the left side

Right side drawer type 3.5 inch HDD enclosure

The hard disk box is opened like this.

Thanks also to Aunt Zhang, who has picked up two Seagate 5T mobile hard drives in Meia. Wait until the goods are removed to stuff the hard drive in.

Then greet my home theater.

100-inch red leaf electric curtain, glass beads.


Because there was not enough space to buy the landing box, the Swans M60 5.1 was started. The entire system bypassed the built-in power amplifier and was directly connected to the YAMAHA amplifier.


Kai Bor K9 PLUS hiding in LeTV, OK. Just blocking two small blinds.

Watching movies with projections is such an experience.


[Kai Bor K9 PLUS UI]

The Kai K9 PLUS UI has been used by KIUI, this time for KIUI9.0, card UI.

Built-in mango TV.

The remote control is a "poster wall" upwards - the features of the K9 PLUS have been for a while.

Down is "Apply".



Support 5G wifi

Support 4K@60Hz

Supports up to 12BIT video depth of field

Using Android 6.0 system

Application interface. This is not the focus of my attention.

But for a while, try the HDMI IN and Poster Wall, both of which are great features.

I don't care about the music player interface.

Built-in Mango TV.

The content is still very rich. But to members. The poor can't afford it. Not concerned.


Built-in file manager.

This is not bad, while supporting local, USB storage and network device reading.

Unlike other products, you also need an additional third-party app to support it, such as the ES file manager or the white file manager.

Poster wall!

This is my favorite feature.

At the same time support the retrieval of local, USB storage devices and network storage devices such as NAS video data, and automatically network matching posters and profiles.

In fact, the degree of match for standard movie data is still very high.

But because there are many test videos in my device, it is not a standard movie video. Therefore, the degree of matching has decreased.

The matching poster wall also supports classified search.

Networking automatic matching profile.

The poster assistant also supports the operation of the mobile app.

After scanning the code in the lower left corner of the TV, install it on an Android phone and you can operate it on your mobile phone.



Select "Sparta 300 Warriors" Play

Open Bor K9 PLUS HD Player

This has always been a weakness in box products.

Kaibol K9 PLUS positioning is local HD decoding, so for the local high-definition playback options must be very comprehensive.

For example: subtitle selection and special effects, 3D playback, audio track selection, etc. are essential.

For me, this lazy person, the most important thing is to automatically download subtitles.


HDMI IN function

This is also unique to the K9 PLUS. Supports HDMI signal input for picture-in-picture, broadcast, and recording.

I didn't understand broadcasting too much, but HDMI IN is very convenient for picture-in-picture and recording programs.

And program recording supports timing and retrieval over time.

Search by time

Real shot test:

Test music TV and open Bo K9 PLUS box, using the standard 4K test picture. as follows:




4K HD video decoding:

Chi Mei Demonstration - Roast Duck


Distorted big bit rate video - "Duck flew", can also play smoothly

4K demo video real shot



HDR high dynamic display demonstration contrast (note the middle dividing line)


Projection playback test:

Since the BenQ i700 only supports 1080P, the 4K display resolution problem cannot be seen. Only look at the situation of color smiles.

LeTV 4K TV and BenQ i700 Comparison Test

The display is good. LeTV 4K supports HDR, and the LCD screen brightness and contrast are better than the projector, so the display is better.


Just do so many simple tests.

For my classmates playing home theater, I may not even be able to catch the entry level. But for the average user, it is enough.

Through the recent launch of the Bor K9 PLUS 4K Blu-ray player and music as 4K TV, embarked on a 4K no return.

Playing HD is really a bottomless pit. Big sister's villa (Seagate 5T) arrives immediately. In the next step, it is estimated that it is necessary to pick up the 4K projector. Think about it, immediately feel that the wallet is tight.

Smart TV/box information can focus on smart TV information network sofa butler (http://), China's influential TV box and smart TV website, providing information, communication, etc. on TV boxes, smart TVs, smart TV software, etc. Answering questions.
