As more and more earphones become non-standard products of mobile phones, it has become a new task for consumers to choose a earphone that can listen to music and answer the phone. As a leading brand of domestic earphones, Astrid has made frequent efforts in the consumer earphone market in recent years. After the big sale of small steel guns, it launched the AM700 that listened to consumer suggestions, In order to meet the increasing call demand of consumers, this headset has now been upgraded to AM700M. While maintaining the original high level of music restoration ability, it has made a number of improvements. It perfectly adds the call function to see how this headset performs.

PS: Astrotec/Astrid 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. (Baidu extract)

In terms of packaging, the AM700M is also made of green pulp in log color. Compared with the package of an earphone, this paper box is quite large. Only the logo and slogan of Astrid are on the front, which is simple and generous. However, after seeing a large number of millet product packaging boxes, this kind of packaging is also a little aesthetic fatigue

The label on the back is rich in content, mainly including product features, earphone specifications and production information. From the earphone parameters, we can see that this earphone uses a 9.8mm dynamic drive unit. It is said that it is the same model as an international brand thousand yuan earphone, with impedance of 16OHM, frequency response range of 10Hz – 27000Hz, rated power of 3mW, maximum power of 15mW, sensitivity of 106dB/1mw, and Mic sensitivity of - 42 ± 3dB

The inner box is covered with damping sponge, and the earphone body is embedded in the sponge slot, but it seems that the sponge positioning is not very good. The earphone does not stay in place. Take out all the objects, including one earphone, three pairs of plugs, one storage bag, and one manual. The black leather storage bag is not very exquisite, but the manufacturer is full of sincerity

Attached are 3 pairs of plugs, 2 pairs of silicone sleeves of S and L models, and 1 pair of sponge sleeves, which are soft and said to meet the European food standard, and can effectively isolate external noise while improving wearing comfort

This AM700M earphone is rose red and full of air. The earphone chamber is similar to the gourd type split chamber structure, and is made of aviation aluminum. The front chamber is sanded and the rear chamber is metal wire drawing. Two different surface treatment processes appear at the same time, but there is no sense of disharmony, In addition to the middle groove connection and the bright surface chamfering process at the edges of the front and rear chambers, the earphone looks layered. There are air holes in the rear chamber on the side of the body, which can effectively reduce the rumble of bass. The smooth metal convex surface on the back of the rear chamber can also play a decorative role. The overall design is just right

The bottom of the earphone is marked with LR, which is convenient for users to wear. After the plug is removed, the air outlet of the front chamber can be seen, which is used to leak out the sound in the opposite phase and reduce its impact on the sound quality

The remote control of this headset has only one button, which can be played/paused by clicking, double clicking and triple clicking. The functions of the next song and the previous song can be played/paused. However, the speed of continuous clicking needs to be mastered. In addition, when the camera is taking a picture, clicking the call button can achieve the function of taking a picture. This function needs to be supported by the mobile phone. As an upgraded version of AM700, the Mic icon on the remote control is very eye-catching,

The plug is a 3.5mm standard plug with gold plating, which looks beautiful and has better connectivity. The wire is made of TPE material, which is slightly hard. The processing of the connector is slightly sloppy. White glue can be seen at several parts of the earphone sleeve

Seen from the actual use, the effect of Mic calling and recording of the AM700M is good, and the stethoscope effect is also very small. When listening to music while walking, it does not need a large volume to cover up the sound of footsteps and the sound transmitted by wire rubbing clothes

Since the earphone itself is equipped for mobile phones, Bug uses the mobile phone on his hand to audition. At the beginning, he feels a little stuffy, like listening to Adele's Rolling in the Deep In this song, the drumbeat sounds dry and inflexible, and the fast-paced place seems a bit chaotic. After 30 hours of machine burning, this situation has slightly improved. However, for fast-paced songs, the performance of this earphone is very general. In terms of bass, I chose several songs by Zhao Peng, and I feel that the bass is quite sufficient, There is still a few points missing from the excessive feeling. After listening to several domestic popular songs, I felt that this earphone immediately found a feeling. For example, Cai Jianya's When the Next Love Comes, the song interpretation is full of tension, Fan Weiqi's Silent Tell You, the voice restoration is accurate, Tan Weiwei's If There is an Afterlife, the climax of the layered sense of expression is in place, and Park Shu's The Flowers It's plain but not lose details. It's worth more than 100 yuan for this earphone

summary

The AM-700M retains the good sound quality of the previous generation of products. The tri band is more balanced and focuses on vocal performance. It is suitable for listening to songs with slow rhythm. As an in ear commuting headset, it also has a call function, which makes it easy to answer calls when listening to music. The Mic remote control and splitter are also exquisite. The three earplugs and storage bags are also very considerate, It can be said that it is a portable headset that is very suitable for daily use with mobile phones, and it is very competitive among products at the same price.
