Radio is a necessary entertainment tool for many middle-aged and elderly people to retire, with the progress of science and technology, new products of plug-in card type and intelligent radio are not uncommon, in this issue, Xiaobian shares with you a B850 model radio from the domestic King. It has a delicate and compact appearance, with galvanized metal and red plastic as the main color, which is very recognizable, and most importantly, the B850 is fully functional, and can last for 3 days with only one battery, which is very practical and easy to use.
The appearance is a highlight of the B850, and as a representative of traditional radio, its design does not have too many highlights, but it also cannot find a slot. Like the layout of the fuselage, it uses the familiar rectangular horizontal layout ID design, plus the fuselage volume is small enough, and the bezel is rounded and structured, like a pebble, which is super recognizable. The shell material of the fuselage is made of electroplated metal main frame, with plastic shell embellishment, which not only ensures the strength of the main body, but also controls the thickness. Holding the B850 with one hand does not feel cumbersome, even when it is put in a pocket, the feeling of carrying weight is minimal, and the presence of a metal frame can also improve the machine's drop resistance.
Specifically, the front of the fuselage of B850 is composed of three functional areas: external speakers, screens and buttons, among which, the screen and buttons are unified into two areas, left and right. The speaker has a black metal bottom plate as a protective cover for the components, and the opening is large, so you can see the speaker structure inside. The sound playback effect of the speaker was measured, the volume of the machine was turned on to 60%, and the local MP3 music was played, the sound quality was relatively average, and the treble part also had a probability of breaking the sound, and the quality was not outstanding. Considering that this is only an entry-level product, the B850's external effect is not to be expected.
To the right of the speaker is the B850's screen and button area, which are designed together and share a black bottom plate, which is full of luxury. On the bottom panel is part of the screen, and the border is not visible when the screen is off, and it is very pure. After the screen is turned on, I see that the B850 screen is only about 1 inch, horizontal layout, showing red handwriting, supporting plug-in status bar and theme bar, large font size, particularly eye-catching. At the bottom of the screen is the B850's key area, which contains 0-9 numeric keys, shortcuts for radio and loop mode. Not only that, at the bezel on the far right of the machine, a vertical playback shortcut key is also designed, they have up and down song switching, play pause button, which is equivalent to specially operating local music playback, which is more convenient.
Flip the B850 to the middle frame and back cover of the fuselage, these two designs are decent, and they belong to a set of public version of the scheme. Like the top of the middle frame of the fuselage, there are two TF card slots, guessing that one of them is a SIM card modification, because the cost has been replaced with a TF card, and it has been made into a dual storage expansion function, but the practicality is average. On the right side of the middle frame of the fuselage, there is a two-stage power button, a pulley-type volume adjustment button, and a mini USB data and charging port. On the back cover of the B850, there is a battery compartment cover in the lower position, which can be removed and replaced, and the measured battery can easily cope with the battery life of the B850, and it is no problem to use it intermittently for 3 days.
Boot to operate the B850, its main function is the radio. Click the FM shortcut key to enter the radio mode, the default program station is played, but the signal is unstable, you need to manually click the button to switch songs to manually search the station. From the logic of setting up the operation, B850 neither supports automatic search, nor does it have the concept of saving the station, and it is very inconvenient to manually search the station again after each power switch. In terms of radio signal and playback effect, the feedback is better in the upper floors, and there is a high probability that the program will not be received in the lower floors, and it is more smooth to use it during the day and at night. Xiaobian is in the urban area of the second-tier city, and you can find 4-6 radio stations, and the signal is unstable.
Adjust from radio mode to local player mode, and the machine will automatically read the contents of the TF card (if there is no TF card, it will automatically return to radio mode). Xiaobian tested and installed a 128GB TF card, but it couldn't be read, and it was replaced with a 16GB card, and the reading was normal. The mp3 files, wma files, and wav files in the card are all recognized and played normally, and there is no difference in sound quality, which shows that there is no HiFi chip in the machine. In terms of external amplification effect, because B850 is a single speaker, there is no stereo effect, just listen to a sound, and it cannot be used outdoors, its volume is too small.
On the whole, such a Jinzheng B850 radio, its performance and function characteristics are not outstanding. Like the effect of playing music outside, it can only be played indoors, the volume is not large, the sound quality is average, even if it is changed to local FM radio, there is no improvement in the slightest; and in the radio playback mode, its digital buttons can not realize the function of jumping to the corresponding frequency station. For Xiaobian, such a radio is only slightly prominent in appearance, small and easy to carry, and has limited use scenarios.
