Why Eonon can get your money’s worth? There’re thousands of car DVD players in the market, some of them are without brand and very similar to each other. We can hardly discover their differences if only based on the beautiful words and photos. But we would like to do this for you, since Eonon is so confident and proud of our decent products, through this detailed comparison, you can easily find real truth behind. Hope it really helps you to make wise choice.
External Design
1. Appearance
Eonon Non-brand unit

Looking from a distance, there is no notable difference between them. They’re both standard 1 Din units with a LCD screen. The streamline buttons, making Eonon look more fashionable and elegant.
2. Package
Package during delivery process is very important.
Eonon

Non-brand unit

Eonon:
Eonon D1001 is well packed:
A. It uses very thick pearl wool to protect the unit.
B. We specially prepare a plastic box for detachable front panel. Since it’s with glass screen, easier to be damaged. This box can help the detachable panel to avoid any possible damage during shipping process.

Non-brand item:
It also has pearl wool to protect the unit, but much thinner. And it doesn’t include the special plastic box. The possibility of damage will be definitely increased
3. Operation Panel
- Buttons:
Eonon Non-Brand unit

Eonon:
From the product design period, we started to consider how to make a prefect combination of both appearance and operation convenience.
We use high accuracy mould which makes every gap of the unit hardly to see.
The streamline design together with the metal decoration will make a top visual and tactile enjoyment.

Non-brand item:
The buttons are display at random both in size and position which make it not so friendly to use. And the mould design is a bit rough, the gap is very large.
-USB & SD Card Slot
Flash disks & SD card are widely use nowadays.
Eonon

No-brand unit

Eonon:
unit has a special cover to protect the USB port, since if it’s exposed for too long time, it will be filled with lots of dusts, and will lead to uselessness.
Furthermore, you don’t have to worry about the cover will get lost, since it’s connected together with the main board.
We put the SD card slot behind the panel to protest against the dust. Much considerate.
Non-brand unit:
USB port and SD card slot are both located in front of the panel. Not so neat looking and will easily get polluted.
-Connecting base
Eonon Non-brand unit

The connector can easily get bad contact after a long time.
Here goes the open-close test:
Eonon:
Eonon unit uses gilt clips, which have been get through open-close test for 100000 times without problem. 100000 times! It is hardly reached the numbers before you would like to change for an upgraded model.

Non-brand unit:
The Non-brand unit uses the normal copper material to reduce cost. In this way, the connecting base will become the first component to get broken.
You can see from the photo, after several times take off and take on, one part have already get cracked. Both of the female and male connector will have the same problem.
-LCD Screen effect:
Let’s introduce how the LCD screen works firstly. LCD can not give light itself, but it depends on the LED back light to illuminate LCD screen, and the colors are designed in advance. This contrast design of the illumination point will largely affect the whole LCD screen display effect. If it’s not well designed, there will be shadows around the characters or images.
Eonon Non-brand unit

Eonon:
We use super professional design technology, you can read any content on the screen clearly.
Non-brand unit:
You can see the shadows throughout the screen, not so clear.
4. Input&Output
For those who are fond of DIY, please pay special attention to the interface of the unit. Since it plays an important part in the installation process.
Eonon Non-brand unit

Eonon:
Eonon unit uses standard ISO port, so you can install it at ease. In addition, D1001 has special Built-In 5.1CH Audio Output. Buyers can enjoy the top level 5.1CH Surround stereo with amazement.
Non-brand unit:
It doesn’t use the standard ISO port, which will bring much more difficulty to your installation, further, you need to cut the original wiring in your car, don’t you feel a bit pity? Traditional 4CH output only make a 3 star enjoyment.

Internal Assembly
All of the above analysis of external part. Let’s go ahead to discover the internal assembly technology.
5. Assembly technology
Step 1: Detach the panel, you will find a very clean and professional organized internal structure in Eonon unit.
Eonon Non-brand unit

Step 2: After taking out the deck mechanism, you will see Eonon’s main board is also quite clean and professional designed.
But you can even find tape on Non-brand unit’s main board. We don’t really know what will happen during usage.
Eonon Non-brand unit

Step 3, let’s take a closer look at their main boards:
Eonon Non-brand unit

Eonon:
As mentioned before, main board is the core part of the whole unit, Eonon has pick up raw material strictly, high accuracy of PCB design, and elaborate processing fabrication, which all stands for the top level standard and pass the vibration test

From the picture of the Non-brand unit, you can unbelievably see there are tape, unknown yellow dirt, black spot and inside it.
Can it stand a few days’ shaking on the road?
Step 4, let’s take a look at the wires connecting the deck mechanism and main board. Deck mechanism can read the data in DVD, while main board is used for decoding the data to audio and video signals. So the connection between deck mechanism and main board is significant. If the wires meet any problem, the DVD won’t work at all.
Eonon Non-brand unit

Eonon:
Our unit uses high performance connection wires to make sure you can watch the video even your car is in a bumpy road.

Non-brand unit:
It uses the plain normal connection wires, which can not ensure you of the durability.
6.Electronic component
- Power supply IC
Eonon Non-brand unit


Eonon:
We use MP4462, MPS is one of the professional famous car audio power supply IC providers.

Non-brand unit:
It also uses non-brand IC, which is much inferior. The power supply IC cooling fan is not well connected to the ground wire. It may easily get over heated and burnt after long time working in high temperature condition.
- DVD decoder
The D1001 SUNRLUS 8202D decoder has passed the LSCD License from Philips Company, supports various of languages.
Eonon Non-brand unit

- DAC converter(Digital to Analog Converter)
DAC is used to transfer the digital signal on disks to real music melody.

Eonon:
In order to make outstanding sound effect, we have added additional DAC chip WM8766 to Eonon D1001, even it will get much higher cost. It reaches:
-6 Channel ，
-103dB SNR，
-32 bit ，
-192kHz Sampling Frequency
They are representing the first class of car audio sound effect!
Non-brand unit:
Except the low performance DAC, there’s no DAC chip.That’s why even if you bought the almost the same unit but without the same performance.
- Audio processing component
Eonon Non-brand unit

Eonon:
D1001 is famous for its high quality Hi-Fi effect.
We use TDA7415 audio processing chip, here’s typical parameters of TDA7415:
- SNS rate(Signal to Noise Ratio)110 dB
-Total Harmonic Distortion: ≤ 0.05 percentage.
-Input Separation:100dB
-Output Noise:15uV
As DAC, all of them are standing for a top-level car audio system.

Non-brand unit:
Without Hi-fi effect. here’s the typical parameters:
SNS rate (Signal to Noise Ratio): 89 dB
Total Harmonic Distortion: ≤.0.3 percentage.
Input Separation:80dB
Output Noise:100uV

As you can see, it can’t compare to our Eonon unit.
- Amplifier chip
Many Car DVD has built-in amplifier nowadays, including Eonon and this Non-brand unit. But are they using the same amplifier chip?
Eonon Non-brand unit

Eonon:
We use TDA7850 amplifier chip:
High output power:4 x 40W/4Ω max.
Signal to Noise Ratio: 80 dB
Total Harmonic Distortion:≤0.025 percentage
Non-brand unit:
It has TDA7384 chip:
High output High output power:4 x 40W/4Ωmax.
Signal to Noise Ratio: 65 dB
Total Harmonic Distortion:≤0.04 percentage

Although they’re both from ST company, but the performance of TDA7384 is much lower than our TDA7850
-Radio component
Eonon Non-brand unit

Eonon:
It uses highly integrated digital signal radio tuner.
-USABLE SENSITIVITY ：6dBu
-STEREO SEPARATION：50dB
-Signal to Noise Ratio: 80 dB
-Total Harmonic Distortion:≤0.1 percentage
-Operating Temperature Range:-40 to 85℃

Non-brand unit:
It uses half integrated, half discrete analog signal radio tuner.
-USABLE SENSITIVITY ：15dBu
-STEREO SEPARATION：35dB
-Signal to Noise Ratio: 70 dB
-Total Harmonic Distortion:≤0.2 percentage
-Operating Temperature Range:-20 to 75℃
Digital tuner is much more expensive than analog tuner, the performance of Eonon unit will be definitely better.
-Optical head
Eonon Non-brand unit

Eonon:
Our DVD uses Sharp HPD-61 professional optical head to read disks.
Operating Temperature Range:-40 to 85℃

Non-brand unit:
Also, this is a non-brand optical head.
Operating Temperature Range:-10 to 70℃

So now you see the big distinction. You can’t enjoy your in car entertainment in both too hot to too cold weather. Don’t you feel pity? So it’s necessary to take your local weather condition into account.
Never judge the car DVD player only by their appearance or the pricing tag. If the article will do good and help you to make a wiser decision with car audio unit. Then it will be our pleasure.
