Feiao i1 Evaluation: A Good Choice for iPhone Audio Adapter

IMG_5362.jpg


the most painful thing for iPhone 7 users is that they do not provide a 3.5mm earphone connector and cannot plug in your favorite earphone. Fortunately, Apple provides audio patch cord and a choice of 3.5mm interface output. Originally, mobile phones tried to listen to songs simply and conveniently, but now it is really cumbersome to have a "little tail" to listen to songs.


also brings a benefit: originally, many direct pushing parties did not want to replace the front end. Now, due to the embarrassment of the iPhone 7 without earphone holes, they have to seek another alternative. Previously, the small number of Lighting interface portable decoding earphones has aroused the interest of many users.


portable decoding earpiece products with traditional silly design can hardly conquer users who pay attention to portability. This is not flying proud to take a fancy to the absence of this product, to meet the user's requirements for portability and sound, and to introduce its first decoding earpiece with Lighting interface -- i1.

Since Apple is forcing users to use audio conversion lines, how can third-party transfer lines attract users to buy if they don't make some features? Feiao i1 is a powerful driving force for decoding and earring, which can significantly open the sound of the original adapter lines from Apple, and I believe it can satisfy you who are picky.

Feiao i1 is quite simple, with a Lighting plug, a 3.5mm standard earphone jack, a three-stage wire control on the front and a highly sensitive microphone on the side. The headphone jack can automatically identify three-segment and four-segment headphone plugs. Several self-controlled plugs have been tried, and none of them can be used by wire.


In order to ensure the durability of Feiao i1, Feiao abandoned plastic materials and made of integrated aluminum rods. Its length is about 9.5mm, using a screwless design, plus a full-textured matte black color scheme. Feiao i1 has a very delicate feel when touched, which complements the matte black color matching of iPhone 7.


Feiao i1 is quite exquisite in workmanship, the accessories in this package have somewhat failed to live up to the name of "big accessories factory. In addition to i1 itself, there is only one small plastic clip and two instruction manuals. The most basic storage bag does not come with one, which is really not considerate enough.

Feiao i1 is impeccable in workmanship. The measured length of the wire from the interface to the body is as high as 80cm. In addition, the length of the wire of the portable earphone is basically 1.2m, which can be used as skipping rope with a total length of 2m. You can't listen to songs when you go out without a clip.

Feiao i1 is a little embarrassed when it is attached to the earphone. The plug-in earphone plug is integrated, but it is a bit unsightly to try to plug in the "L" earphone plug. Especially for the earphone line changer party, it is really bad to insert the "L" plug of Euryad.

worth noting that when Feiao 1i connects the device for the first time, a prompt will pop up and it is recommended to install FiiO's management software. However, it is embarrassing that this software only provides Feiao i1 firmware upgrade function at present, while common EQ adjustment and other functions have not been added. I hope that these functions can be added in the later software update.

, because Apple's own tuning concept is too bland, many direct pushing parties don't sound good. This situation has improved a lot after owning Feiao i1. The most direct change is to make the voice more enthusiastic and full.


thanks to the use of a NAU88L25 decoding chip in Feiao i1, which supports playback of audio with a frequency response range of 20Hz-20KHz, the output power can reach 30mW under 16 ohm impedance. The gap with the direct push of the mobile phone is equivalent to the difference between a full meal and a half-full meal, and the output sound is solid and powerful.


decoding is a bit embarrassing, because Feiao i1 is certified by Apple's MFi and is suitable for all Apple's devices equipped with Lighting ports. Limited by the sampling rate of Apple LAM module, it currently supports audio sources up to 48KHz, which is higher than the CD level of 44.1KHz, making it difficult to give full play to the powerful decoding capability of Feiao i1.

data is one aspect, how the sound still needs to be actually listened to before a conclusion can be drawn. This test earphones are tested by NF2 under NF AUDIO. It is well known that the earphones produced by NF AUDIO are famous for their poor driving. I believe that such a combination can experience the strong strength of Feiao i1.


Compared with the audio patch cord of iPhone 7, the most intuitive improvement of Feiao i1 is to make the sound more pleasant. Compared with Apple's plain boiled water tuning, Feiao i1 is dynamic and clear and bright. I believe that such sound is difficult to experience on Apple devices..

Feiao i1 has the characteristics of completely bringing hi music, but its tuning defects are also quite obvious. In order to ensure that the person's voice is warm and cordial, Feiao i1 can only choose warm voice training. Of course, warm sound is not a disadvantage, but the problem is that while the bottom of the sound is warm, the low frequency is too fat and not clean enough. It's okay to listen to this kind of tuning and popular, but it will only make you feel a mess to listen to piano solo or new world music.


a closer look at the market that Feiao i1 faces, that is, some users who hate the tuning of Apple's plain boiled water, such popular tuning can gain a lot of favor. After all, on the basis of limited materials and quality, it is better to completely become popular, at least to make users sound more refreshing.

praise is that the price of Feiao i1 is not expensive, and the cost-effective pricing can be said to continue FiiO's consistent style. The Lightning connector it uses has passed Apple MFi certification, so there is no need to worry about the risk of failure with the iterative upgrade of the device system. This is the biggest difference between it and the products used by system vulnerabilities on the market.


get a complete use experience, which is the charm of Feiao i1. In view of the high requirements of some users for portable decoding earphones, there are also many products like Senyun Lancea on the market, but the price has increased a lot, and there is no wire control support.


Low Threshold Lighting Decoding Earrings

compared with the same type of products on the market, the biggest advantage of Feiao i1 is that it can provide a complete experience on the basis of a lower threshold. It can actually solve the pain of users using headphones at ordinary times and give them simple and convenient wire control support. There is also a perfect software upgrade firmware to meet the room for upgrading the audio output of Apple's Lighting interface in the later period. The only inconvenience is that the wire design is too lengthy.


looking at the audio devices for Apple's Lighting interface in the market, there are only a handful of MFi authentication devices, and there are even fewer products that can add wire control function for users to carefully consider. Now Feiao has given all this to i1, and such a value-added product is actually the first choice to replace Apple's original audio adapter.


on the other hand, according to Feiao's initial introduction of the X3 portable player routine, maybe with the popularity of Lighting interface audio equipment, or will launch a higher-level version of i3, i5? With the current comprehensive use of Feiao i1 experience, I believe that the subsequent upgrade will be favored by more people..
