Android version of "National Brick" DX100 hands-on experience | Love Computer - 上海419贵族宝贝-上海后花园1314-上海品茶网-阿拉爱上海

When the term "national brick" is mentioned, the average netizen may not have a deep understanding of it. In fact, it is a nickname given by walkman enthusiasts to some domestic audiophiles. For example, the iBasso DX100 we introduced today is an outstanding player in the national brick market, and it also rarely uses the Android system.

Wait a minute, little editor. Don't you want to evaluate the walkman? How did you put some cell phone data? In fact, the configuration of DX100 is similar to that of the mobile phone a few years ago, and DX100 is equipped with 64G ROM, which is also "massive" in the flash walkman on the market.

Appearance design

The DX100 package is brown and looks retro, with a logo ▼ engraved on it

There are relevant accessories and warranty cards on the bottom of the box ▼

Not many accessories, from left to right are coaxial line, microUSB cable, charger ▼

The front of the DX100 is very similar to the Android phone. It is also a screen. It is equipped with three touch keys. The key functions are menu, home key and return. Everything is very similar to the Android phone. Of course, the DX100 has no earpiece, microphone or corresponding sensor ▼

Three touch keys without backlight, similar to Xiaomi 2 ▼

"Three section" design is used on the back, and brushed aluminum magnesium alloy material ▼ is used in the middle

Brand related information is on the nameplate of the fuselage ▼

On the right side of DX100 is the volume key and Micro SD card slot ▼

The workmanship is quite exquisite ▼

On the left is the switch and restart button ▼

It can be seen from the bottom that DX100 is very thick. From left to right, it is 6.35mm headphone interface, 3.5mm headphone interface, linear output and gain adjustment ▼

Gain is divided into three gears ▼

The top of the fuselage is the charging interface, Micro USB interface, optical fiber output and coaxial output ▼

UI

Since it is an Android system, let's also take a brief look at the UI design of the DX100. The DX100 uses an Android 2.3 based system. Unlike the native system, the DX100 launcher cancels the secondary menu. The settings of the launcher are also very simple. They focus on music playing

Set menu. Players who have used Android 2.3 should feel very friendly about it ▼

The system is based on Android 2.3.1, kernel version 2.6.32.27, and the total usable capacity exceeds 60G ▼

Since it is a walkman, the music playing function is of course the most important. The DX100 player is very powerful. In addition to the common equalizer settings, it can even set digital filtering and SRC ▼

DX100 is also the first player to use independent bottom driver, breaking the limit of Android system on audio 16bit/44.1kHz ▼

The running points section is simply skipped. We can't ask too much ▼ for a walkman with a single core processor

DX100 supports Google services, with Google Play ▼

It is difficult for ordinary consumers to understand these parameters, but it is certain that DX100 has reached the top level in the walkman category no matter which indicator it is.

The DX100 uses the top ES9018 as the DAC. In addition, its materials and circuit design belong to the highest level in the walkman. Its sound quality is also sought after by many enthusiasts. We also conduct a simple listening sense test here.

Test headset: UE10

Test song format: FLAC, WAV

Sound effect: off

Gain: middle range

PS: DX100 has been on hold for more than 50 hours before audition

The sound of DX100 is neutral and balanced when it reaches the ear. It belongs to the type with excellent quality and sense of hearing. DX100 has excellent analysis, and its sound field is larger and more regular than that of a typical walkman. It sounds much more comfortable than some horizontal sound fields that are pulled open, but vertical sound fields are very restrained. The neutral sound of DX100 enables it to play well in many different types of music. DX100 is more balanced and authentic than some products with distinctive voice, such as HiFiman series, and does not feel too stained. For some players with grand sound and suitable for musical instruments and classical music, DX100 will be at a disadvantage in this respect. The DX100 is slightly lacking in sound dynamics and momentum, giving the impression that the sound is very durable but lacks shock. For some analytical devices like the D50, the DX100 sound will be warmer and softer.

In terms of thrust, since the editor only used earplugs for audition, it is certainly no problem for the national brick of this level. Many people said that the sound level of DX100 with HD650, Q701 and other earphones is acceptable. In terms of bottom noise, the DX100 also performs exceptionally well. In the combination with UE10, there is no bottom noise even in touch operation. For a high-level walkman like DX100, the quality is believed to satisfy most people, and its high balance also makes it more flexible in matching earplugs and earphones.

We will also follow up the detailed sound test of DX100 and its comparison with other walkmans in the next article.

It should be noted that the DX100 is very hot when playing music (most national bricks have similar problems), and the tested surface reaches 41 ℃ (room temperature 27 ℃), so pay more attention to heat dissipation when using ▼

summary

In general, DX100 is an excellent "national brick". Excellent sound quality is the biggest significance of national brick. DX100 does a good job in this regard. Excellent quality, balanced and neutral sound style improve its sound endurance. But also because of the Android system, there are other problems on the DX100 that are not found in the walkman. For example, the touch operation is stuck, and the system bugs are all points deducted from the user experience. Of course, the DX100 player is hard to see on other walkman players in terms of intuitiveness and functionality. Digital volume control also allows us to adjust the volume more accurately. For the price of 5200, I believe that normal people will think it is not worth it, but if you are a fan with high requirements for sound quality and good money, I believe that the performance of DX100 will make you feel it is worth it.
