Product out of the box
       The Astrid GX20 continues its concise and sturdy design style. The GX series are sports series. Accessories finally came with a headset storage bag, ear plug part comes with three sets, but two sets of silicone material, the other is similar to the memory cotton elastic earmuffs, may be the reason of the material is not high temperature, has been sticky station Together. So I still hope that the earmuffs will all be replaced with silicone, after all, I'm used to it.
       The storage bag is made of thicker velvet material, soft to the touch, fine workmanship, and not worth picking. Although it is a sports headset, the length of 1.2M wire also needs to be fixed. The KEVLAR material is used for the headphone cable. The resistance to pull and bend is excellent and the elasticity is very good.
       This headset has two colors, one is Neptune Blue is Crystal Violet, at hand this is Crystal Violet. The design of the GX20 is a bit special. First, it adopts a transparent design style. The internal structure can be seen through the plastic housing. The second is a slightly unique 40- degree inclined cavity design. The faint feeling is like a hair dryer. This design is not only for wearing comfort, preventing falling, but more importantly, improving the noise reduction effect and reducing noise interference. Plastic housings do not use screws, but are combined together by means of snaps, making it somewhat difficult to disassemble.
The GX20 uses a 9.8mm strong NdFeB unit developed by the Astrotec Acoustics Laboratory to provide a clear midrange and deep bass. However, the actual audition results are as follows.
       As a headset with 3.5mm standard plug, GX20 also uses a gold-plated technology, compatible with iOS , Android , Windows and other smart phones, of course, can also be used with notebooks and other equipment. 16Ω impedance with high sensitivity 102dB/mW , easy to drive.
       As a headset that can be called, the GX20 supports the remote control function, which allows you to easily answer and hang up the phone, pause or play music, and add or subtract volume to the next or previous song.
       The MIC hole is designed on the back of the line control, but the push-pull switch at the top has not found any effect in use.
The GX20 is designed with a cord retainer on the headphone cord, a large, fixed, and the other is a practical design that can be moved up and down to accommodate different lengths.
Enter the actual experience stage below.
product experience
       Headphones, like the speakers, are used to listen to sounds. But not the same, one is to stay in the head, and the other is to be placed somewhere. It is said that acoustics is metaphysics. It is indeed. But for our non-professional enthusiasts, it is to rely on their own audition experience to assess whether the headphones or speakers are suitable for themselves, whether they can meet their own audition requirements. For the headphone speaker, in fact, as long as there is contrast, the sound performance is easy to hear good or bad.
       The title and the opening mentioned are carefully adjusted for the iPhone because the contrast between the performance of the same song on Android phones and the iPhone is obvious, and the vocal part is like opening a movie theater or a theater mode. The voice sounds a bit empty and unreal.
       Regardless of whether it is an Android or an iPhone , the plug cannot be fully inserted into the headphone jack and cannot be inserted in the end.
Line control function
       The buttons on the remote are crisp and flexible. But the button function is slightly different experience
With Android or iPhone , you can use it normally when you answer and hang up. However, different phones use a long-press answer button to wake up different programs. For example, the iPhone will wake up Siri . During music playback, double-click the answer button to switch the next song. Pressing or double-clicking the volume button will not switch songs. The push-pull button mentioned in the front box is actually the hold button ( lock ) , and it works for the volume plus/minus key.
Noise reduction effect
       With the phone actually experience the QQ call, ordinary phone experience. Passing on the side of the road or in the crowded environment of the park, the other party can clearly hear the content of the dialogue. There is no current noise or obvious noise, and normal conversation is not affected.
       Whether it is talking or listening to music, in the normal setting of the volume environment, you can hear the sound inside the headphones more clearly, while the external sound is not completely cut off.
Listen to the song
       As a sports headset, what are your expectations for its sound performance? I only hope that the part of the voice can be stable, whether outdoors or indoors. In accordance with the old rules, one after another began quietly listening for 61 hours.
The performance of the high-frequency part of the resolving power is general, relatively stable, no obvious sharp feeling or burr sense, and there is not much surprise on the whole. The details are in place, such as the breath sounds of the players in "Mutter Violin." However, it is not suitable for listening to violin songs. The sound quality is lacking, and it is not clear and dull. It does not show enough depth in the high-frequency part. In contrast, songs like “High Mountains, Flowing Water†and “Jasmine Blossoms†are relatively clear and crisp, and high-frequency performance is relatively stable. However, the treble part of “Bamboo Flute†is slightly vibrato, and the ears are slightly uncomfortable.
In contrast, the vocal performance is remarkable, relatively clean and clear, the sound quality is solid and accurate, and the degree of reduction is high. Whether it is the singer Zhao Peng, Cai Ma, or a pop singer's song, the overall performance gives people a feeling of closer distance, no sense of distance or sense of separation, and a kind of sense of distance singing around. The degree of separation between vocals and instruments is moderate, and vocals are not overwhelmed or obscured by instrumental sounds, nor are they masked by instrumental sounds. For some of the background sounds can be accurately and easily realized, whether it is the singer's breathing sound or the cries and frogs in Tsai Ma's "Moonlight Serenade", can be clearly demonstrated. Only the sound of breathing or saliva is louder, and you will feel slightly uncomfortable.
The bass effect of rock songs is prominent, and the vocal part is easily concealed by the sound of heavy metal instruments, whether it is LinkinPark 's " The Catalyst " or "Rock disco" "Century 2000 ", 30s to Mars " This is war ", Some of the vocals are drifting far enough to express the passion and sense of power of the singer, so they are not suitable for listening to rock songs.
The GX20 's performance on points is also relatively good, and it is more than enough to show the kind of orientation on the scene. For example, in the “ Hotel California Live â€, “ F16 Fighter†and “The Wilderness of the Wildernessâ€, the far and near sound changes, and the change of distance can be felt more truly.
Compared to high-frequency performance, low-frequency performance can be said to be an unexpected surprise, excellent analytical power, sound quality and solid performance, deep dive. There is no challenge for the songs in “The Sad City†and “Drum Poetryâ€, even if the opening sound of the low instrument is enough to be easily demonstrated. In Tragic City, the convergence of different instruments is very natural and smooth. Even if the instrument changes from bass to treble performance, there is no sense of drag or suddenness. The deep drumming and crisp drumstick percussion in “Drum Poetry†is in stark contrast. The percussion sound is powerful, and the dense percussion sound in the latter half does not give people a sense of boring or chaos. Not bad.
Judging from the overall audition results, the GX20 does have a clear bias toward low-middle performance, especially with respect to vocal performance.
Wear experience
       As an in-ear earphone, one problem is the feeling of wearing ear for a long time. If it is unreasonable in design, it is easy to slip into the ears and the second is to feel sore. With the GX20's ergonomic design, it is more comfortable to wear. However, for in-ear headphones, do not use too much time for continuous use, so as to avoid hearing damage.
Experience summary
    More and more Hundred Dollars and more headsets are beginning to appear in an endless stream. Although some products are also made of strong magnetic NdFeB units, there will be relatively large differences in the tuning effect and design, and it will also bring about actual audition. Great difference in feelings.
As a headset with more than 100 yuan, comes with the line control function, to meet the needs of ordinary call headset, although not suitable for Android devices to listen to music, but with iPhone and desktop, the experience is still relatively good . If you just want to hear a sound, not wearing it for an extended period of time, then Estimer GX20 is also a good choice if you estimate that the ten-element headset will satisfy you; if you are accustomed to listening to music with your in-ear headphones, you must also answer the call. To wear running, but the budget is limited, then the GX20 is worth your consideration. But before buying, you must listen to the scene and feel it yourself.
