Astrotec is one of the well-known brands in the field of HIFI acoustics in China. It was founded in 2002 by several backbones with more than ten years of rich experience in the audio equipment industry. Some of these people came from the top acoustic research institutes in China, and some of them were important technical backbones in international acoustic factories. "Astrotec" is composed of Astro (starry sky) and Tec (technology), which means Astrotec's endless pursuit of technology exploration.
At present, there are several series of Astral products:
AM stands for Ashtree metal series, mainly dynamic units.
AX represents the excellent series of AstraZeneca, which mainly focuses on multi unit design.
The AS headset series represents the Astrid portable headset series.
BX Sport Series represents Astrid's sports Bluetooth headset series.
GX outdoor series represents the combination of Ashtree music and fashion series.
Lyra, which means Lyra, is also a high-end flat ear earplug series of Astrid.
Orion, which means Orion, is also Astrid's flat diaphragm earphone series.

The protagonist of this activity, Ashcui GX20, is an outdoor commuting headset, which is specially designed for the working people. It is comfortable to wear and can effectively filter out the external noise, so that the working people can experience the enjoyment of music on their way to work.

Of course, the first thing I saw was the outer packaging of the Astrid GX20. The first impression I got from this earphone was the packaging. You can see the picture. At the price of 149, the quality of the packaging is enough to show the seriousness of the manufacturer. The popular front flip design of the packaging box enables the buyer to preview the entity of the Astrid GX20 headset without opening the packaging, which is very user-friendly.

Next, we open the package. The earphones are inlaid on the sponge panel, which makes people feel very simple. A layer of translucent frosted protective cover is attached to it, which not only protects the earphones, but also makes the package of earphones look more exquisite.

The Neptune blue Astrey GX20 earphone looks very fashionable. The earphone shape designed according to ergonomics makes it look full of science and technology.

The ASTRI GX20 headset has a very comprehensive remote control function. It supports volume increase and decrease, answering and hanging up the phone, pausing playing music, the previous song and the next song, etc. In addition, there is a universal switch for system matching and switching. There is also an intelligent noise reduction microphone, which can accurately judge voice and noise, effectively reduce the interference of ambient noise, and maintain clear communication in street, bus, subway and other smashed environments. In addition, please pay attention to safety when walking on the roadside and listening to music with this headset!  

This is the product quality assurance card attached to the headset. In addition, a headset flannelette bag is also attached, which makes it convenient to store the headset when not in use, avoiding the trouble of headset damage and wire winding.

The quality assurance card of tall style adds a lot of power to the earphones.

The AstraZeneca GX20 earphone was previously a direct plug. After the manufacturer's improvement, the AstraZeneca GX20 earphone was changed to a right angle plug. This improvement can effectively avoid the disconnection of the earphone plug. It can be seen that AstraZeneca manufacturers are still serious about making earphones.

The earplug is equipped with 9.8mm strong rubidium magnet boron unit, the sensitivity is 102dB/mW, the frequency response range is 10-22000Hz, and the impedance is 16 Ω.

This earphone gives me a particularly good impression on the wire material. I like this kind of soft wire material that does not have creases. I see that the wire material that can not be straightened when it is folded is really annoying. The wire material of the Astrid GX20 earphone uses KEVLAR material of the same level as the parachute. It has excellent performance of strong pulling and strong bending. It has good flexibility. After daily folding, However, as long as it is allowed to hang naturally, the wire is straight, which I like very much. Such wire is not easy to tie.

Now let's take a look at the family photo of Ashtree GX20. In addition to the earphones, there are three sets of spare earphones. You can change them according to your own preferences, which is very good.

The wire control of the Astrid GX20 headset is regulated by the manufacturer and can easily be compatible with the systems of iOS, Android, Window and other smart phones. The microphone can effectively suppress external noise and make the call clearer and smoother. The touch of keys is also good, and there will be no misoperation.

In terms of sound quality, as for the classic song Ferry, the midrange is quite good and belongs to the high quality, but the bass is not honest enough. The sound enhancement effect of the mobile phone was changed to the bass mode, and the bass sound quality has significantly improved. In general, the sound orientation of this plug tends to be popular, and it is more suitable for listening to popular or ACG. However, considering that the Ashtree GX20 is a headset with a price of 149, This sound quality can almost kill other earphones within 200 yuan in a second, so the Ashtree GX20 is still a headset worth getting experience at the price of 200 yuan.

In general, the Astrid GX20 headset is one of the best earphones I have ever experienced within 200 yuan. In addition to its multi scene applicability, more comprehensive remote control function, and good sound quality, the Astrid GX20 is worth recommending as an entry-level full-time HiFi fever commuting headset.
