# Ear Evaluation# Summer Solstice Is Not Arriving-Pindu Feiao M7

order

we all had dreams, but we were already past the age when we woke up.......

strictly speaking, the author started burning from feiao. With the age of working hours, the pockets are no longer as cash-strapped as they were when they were students. So my brains got hot and I bought one for a lot of money.HTC's flagship "M7", domestic version 802W. At that time, the author still liked this mobile phone, even downloading tens of GB of music files in the memory card, and specially equipped it with the well-received "high-end" earplug GR07. However, unfortunately, although this mobile phone was still of good sound quality in those days, it could not push the plug with an impedance of 80 euros (in fact, it is not as good as the mobile phone can push it now). It coincided with the promotion of Feiao E18 on the Internet: this is a professional decoding ear device specially designed for Android phones. In view of the fact that the OTG function of mobile phones was not yet popular, even the matching recommendation was based on HTC M7. Therefore, in line with the "vanity" mentality of loving my dog and Wu, the author gritted his teeth and took down E18 like a ghost, starting the so-called "fever journey".

in those days, Feiao's earphones were far more famous than players. AndE18, as a "cost-effective" decoding product, is said to have a quality that can even compete with the hot-selling player X3. In a sense, this is also a veritable "youth trendy product". Therefore, for a long time since then, in addition to being too large to carry, the author still loves this earpiece product. Look around for relevant evaluation articles to satisfy your winning psychology. In the long run, I started my "post bar" career by the way. There is no doubt that at that time, I was definitely the "iron powder" of Feiao, and I often made up some so-called experiences and felt in Feiao Bar. Occasionally, I will be excited for a long time when I meet some bosses such as Zhong Gong and so on. That kind of mood is like the kind of worship from the bottom of my heart when fans are received by idols. So I bought X5K and X7 products one after another, and slowly got to know Tangtang, Xianghe, Alice and other bosses. It can be summed up in this way that although the author loves audio equipment for a long time, it is still necessary to count the period of time when I really go deep into the bone marrow and cannot extricate myself from this period of enlightenment. Later, I participated in a joint essay solicitation organized by Feiao Bar, Guozhuan Bar and Dayinke Bar. By chance, I got to know the big brothers such as balls and vaguely one after another. Later, I found that Xianghe was also quite active here... So, I slowly took root in the brick bar.

, there have been many interesting episodes. Thanks to Feiao Guan Bo Niang Tangtang, this kind child has given me a lot of selfless help. Without her help, there might not even be a post bar trip. Therefore, I sincerely thank her from the bottom of my heart. Later, for some reasons, she left her post. Later, perhaps it was because there were fewer and fewer familiar friends. As the topic became less and less, she slowly disappeared from this bar.

get back to business

I wrote an evaluation into a long-written memoir. Looking around, I think it's just me who is so shameless.

more than a year of light is like a white horse crossing a gap. During this period of time in the National Brick Bar, the author has participated in many rounds of auditions, and finally the eye (ear) circle has opened up. Although the fallen flowers are intentional and the flowing water is merciless, perhaps because they are unknown, the author of Feiao's products has always been difficult to get audition opportunities. Fortunately, through the friendship and help of many friends, Feiao's follow-up products also listened to 7788. It can be regarded as witnessing the growth of Feiao from the side.

this time, after several years of absence, it is really an honor to participate in the tour audition of this new product in Feiao for the first time in his life.

to be fair, this product is not summarized at its high end.the X series, but the M series for mass consumers. However, at the beginning of the registration, this product has several selling points that have deeply attracted the author's desire to find out. The first is Samsung Exynos Dual 7270 processor.: As Samsung's first mass production14nmprocess,7270 integrates two ARM Cortex A53 cores to achieve a good balance between power consumption and performance. thanks to the advanced 14nm process, Exynos 7270 can improve its endurance by at least 20% compared with the 28nm process. with the help of Samsung's SiP-ePoPlaminated packaging technology can be integratedDRAM, NAND flash memory, power management IC and other components, the package size is smaller and the power consumption is further reduced. In view of this,FeiaoM7can achieve up20 hours duration.

M7is actually a pure oneAndroidpedigree. Familiar with FeiaoX7, X5 Ⅲ or X7 Ⅱ are absolutely familiar with M7 UI. Although it uses a very streamlined native Android systemIn-depth customization,UI stylealso adopts today's mainstream flat design. In addition, in touch interaction, FeiaoM7even canceled the traditional virtual key design and switched to similariPhoneX gesture control scheme,can realize the function of traditional virtual keys by drawing on the lower sides of the screen. Accordingthe details of UI and secondary menus, it is still not difficult to see that the underlying operating system is a fake native Android. Through the menu font and color matching style, the author dared to guess that the Android version of the machine is probably the mainstream Android 5.X. However, in order to ensure the absolute smoothness of the system, the government deliberately limited the APP to a simple level and did not open the relevant user permissions to install or uninstall the APP.

Compared with Japanese or KoreanAndroidplayer has already streamlined the system beyond recognition.UI design is obviously a compromise. For this reason, it also gives the author such inspiration: if users can obtain the relevant developer rights through ROOT and other means, it is still very likely to delete or add the corresponding APP. of course, it is an indisputable fact that M7 does not configure too much RAM for the whole machine due to positioning. In fact, at the beginning of X7's launch, there were quite strict restrictions on APP installation rights to ensure the stability of its system operation. Even at that time, only 1G of ROM space was allocated for APP installation. Of course, there is nothing absolute. Later, at the repeated request of users, the subsequent versions of Feiao successively opened relevant permissions. Therefore, it is not known that small partners with strong hands-on ability can obtain higher-level permissions through intelligence (ROOT). This is also the charm of Android. However, there is also the risk of "brushing bricks" or losing warranty rights due to brushing machines. ROOT is risky, so brushing machines should be cautious.

at the coreFor DAC selection, Feiao M7 uses ESS 9018Q2C this time. It integrates traditional DAC, earmuff and output selection functions. It not only effectively reduces the overall size, but also has bright performance parameters such as 121dB signal-to-noise ratio, 115dB distortion, and 384kHz/32bit, thus obtaining long endurance. It is not difficult to see that ESS9018Q2C also comes from the well-known ESS9018 series, which is famous. It adopts more advanced packaging technology to integrate ESS9018K2M + ESS9601K. In view of this, the sound quality of M7 can still be effectively guaranteed.

the compact appearance of 52mm * 109mm * 13mm, only 116g weight. There is no doubt that M7 is currently on sale Android.the smallest player in size, at the same timeCPU architecture and 14nm manufacturing process are undoubtedly the most advanced ones in the players sold. Therefore, this player can theoretically be upgraded all the way to the latest Android8.1 system. This is definitely a good thing for an Android player.

M7 has built-in Samsung Bluetooth chip, adopts Bluetooth 4.2 standard, perfectly supports 24bit Bluetooth aptX-HD protocol and backwards compatibility aptX standard, and creatively adds LDAC wireless transmission protocol,Compared with the traditional Bluetooth standardThe transmission bandwidth of 328kbps. The LDAC can reach up to 990kbps.fists in hand, for users who are used to listening with Bluetooth headsets, FeiaoM7 is greatly improved compared with the Bluetooth sound quality of traditional smart phones.

, as a major accessory factory, Feiao has always been ahead of friends. FromX5 era, Feiao has equipped the machine with 3M stickers with excellent fit and wear resistance. Since the X5 III era, it has also equipped the original tempered glass film with excellent workmanship, the transparent soft cover and the original leather cover with high fit, which can be said to arm the user's love machine to the teeth. It saves the dilemma of users searching all over the world for toughened films and leather covers to no avail, and truly achieves intimate service without dead ends. There is no doubt that this M7 is also equipped with pre-pasted toughened film and extremely slim transparent "crystal cover", and is equipped with multi-color original leather cover. It is really full of sincerity.

M7 is integrally formed by aluminum alloy die-casting, and only the upper part of the body is treated with window patch to ensure Bluetooth and LDAC.the stability of the signal. The design is in the same line as Feiao's design concept: Founder and dignified. All edges and corners are adoptedCNC small bevel cutting angle treatment and fine grinding, the whole machine is given anodized frosting treatment. The cutting process of the inclined plane of the left metal runner is exquisite, and the concave design is made on the edge of the frame, which not only effectively protects the misoperation of the runner, but also makes the overall design more flexible. The whole machine manufacturing process is in the forefront of domestic player manufacturers at present, and the top three are also worthy of the name. Although M7 was criticized at the beginning of its launch, its overall design style was "serious" and borrowed from a major international factory, and the design concept of "brain door" made this product quite top-heavy.

to be fair, if this player is appreciated upside down, it will really have to endure a lot. Unfortunately, if the pulley is placed under the fuselage, it will be quite cramped in operation. However, this product is Android after all, and the next version will be added casually.the "screen rotation" function? In this way, it is natural to "pay equal attention to beauty and talent.

worth mentioning that after several generations of product wheel design changes,M7 wheel seems to have a kind of high-end watch gear bite tight feeling when it is flipped, and the hand feel is outstanding. The key design style of "red circle and blue eyes" above the fuselage originated from X5 Ⅲ, and its blue LED strip was once reflected on X7. This also witnessed from the side the same line of Feiao's product design. There is no doubt that this time the M7 only provides 3.5 single-ended earphone holes, but intimately integrates the LO port function. There is no 2.5 balance earphone hole, which reduces the cost in a certain sense, and once again makes the product positioning clear.
