Foreword
Everyone who likes to listen to music chasing American dramas is eager to find their own speakers, know each other and know each other. This is not a matter of fact, but it is not a matter of fact, so from time to time to buy new speakers to experience.
For those who like outdoor sports, outdoor sports and cycling, they like to listen to songs but do not want to bring headphones. A waterproof portable speaker is necessary, and music is not so boring.
Polar Night A5 is an outdoor sports portable Bluetooth speaker, can be used as a Bluetooth speaker, can be used as a radio, support Bluetooth, AUX and TF card three playback modes, of course, this is only standard, otherwise more boring, in the same product What are the competitive advantages? Extra points can be used as flashlights and mobile power, and can be used for emergency charging of mobile phones and other devices. In addition, as an outdoor equipment, it is also dustproof and waterproof.
As a portable outdoor device, the A5 measures only 1565151mm and weighs only 260g. It is shorter in altitude than the flashlight for outdoor camping. The accessory had only a white, short MicroUSB power cable, which was not available on the AUX audio cable at first, and was slightly disappointed.
Light bulbs use popular patch-type LED light beads (1W), which are yellowish in color, and the lenses use PVC light-transmitting sheets, which have good light transmission.
The figure below is a comparison of the actual outdoor photos at 4 o'clock in the afternoon. The brightness is brighter than the one on the hand, and the light color is really yellow.
As an outdoor flashlight, it is useful to ask for help. A5 also has three light modes, the default is the strong light mode, the brightness is high; press again to switch to ordinary light, more power saving, the brightness becomes lower; the third is a continuous flashing (one second per second) for help or Warning light. The yellow light looks more eye-catching at night.
Corresponding to one end of the flashlight is a horn end, and a speaker with an output power of 3W is used, and a double horn design is not used. The outer net is made of metal material, which is relatively smooth, without graininess, and it is more detailed in workmanship. Â Â
The A5's body is actually black, consistent with the black on both ends. The material in the middle of the blue is just a layer of rubber waterproof and dustproof silicone sleeve. It can be disassembled and more vibrant in color. But don't check it out and use A5 directly because the following buttons are bare. The surface of the silicone sleeve has a non-slip design, and the non-slip granules in the middle are symmetric and easy to hold. Â Â
The main buttons and interfaces of the A5 are all designed on one side, namely the top of TOPFEEL. The black part of the frame can be lifted. The corresponding M key on the left side is the mode switch key, and the +- key corresponds to the volume plus/next track and the volume down/up track. The small round hole is used to call the MIC hole. The right power button is the key to the independent flashlight. And so on, what about playing and pausing buttons? It uses the M key to achieve song pause and play functions.
After opening the middle silicone cover, you can directly see the interface below. TF interface, 5V-1A charging interface, power indicator, push-pull type speaker switch button, AUX interface and USB interface. In addition to powering the device, this USB interface can also be used? U disk, card reader play songs can it? The following verification. Built-in battery 4000mAh, although it seems that capacity is not big, but the emergency charge for the phone is still fully capable.
This is the way she streaks after the silicone sleeve is removed. Pay attention to the recessed part of the physical button, you can see the lower part of the sheet metal. There is only one LED, which is blue. Just after the seal is closed, the indicator light is not visible at all, but fortunately there are voice prompts to make up for this shortcoming. Â
In addition, the A5 is also designed with a diaphragm outlet hole, which is the hexagonal round hole below, and it seems to be designed in detail to enhance the bass effect. The middle jack is a standard tripod jack, which can be directly fixed on a tripod. Black screws with perforated screws can be hung on a schoolbag or bicycle and other equipment through a lock.
Enter the actual experience below.
product experience
Although it is an outdoor Bluetooth speaker, not even 2.0. However, out of respect for the speakers, or in accordance with their own way to carry out more than 60 hours of cymbals speaker, whether it is necessary to chant the speaker varies from person to person, different gameplay, cognitive differences, seeking common ground while reserving differences. However, the part of the sound quality review is placed last.
Let's talk about the speaker switch key, the first thing people think of is the same key design on the toy car, there is a sense of cheaper, more resistance, experience in general. There are English voice prompts at startup, which sounds like a tall feeling. The default is Bluetooth mode, long press the M key to switch modes for two seconds.
Note that the song playback in the TF card supports the memory playback function, which is a very practical function design.
If the AUX audio cable and the TF card are not connected, the switching is only switched directly between the Bluetooth and radio modes. The normal switching sequence is Bluetooth-TF card-radio-AUX-Bluetooth switching. When AUX is inserted, the priority is the highest, and AUX mode will be directly switched to. When you remove the TF card or AUX audio cable, you switch directly to radio mode. As a Bluetooth speaker, Bluetooth compatibility and stability are very important. Mobile phones, tablets, set-top boxes, TVs, and computers should all be connected properly. A5 did not fail during connection to the device.
As a speaker that supports TF card, whether to pick a card is also a question worth considering. Tried several existing TF cards on hand, there is no unidentifiable situation, of course, the format is to support the FAT format. The test method judges whether the song can be played directly.
The interface used to charge devices such as mobile phones and tablets is easy to use and can be used to charge the device when plug and play. With the iPhone 5c and ASUS Zenfone ZOOM for actual charging tests, charging can be performed normally, and the A5's body is not severely heated.
Then can the USB port used to charge the phone recognize the songs on the USB stick or card reader? I am sorry, but I can't. At present, I can only use it as a power output. I'm sorry to say that in principle it is possible to use a bit more.
The search efficiency of the radio is worse than that of the landscape. The number of radio stations in the same location is the same. The signal clarity of some radio stations is not as good as the landscape effect. The sound quality is not much different, but the signal reception effect needs to be improved.
Waterproof can only be regarded as waterproof, water rushing or short-term water immersion. It can be used continuously. As for wanting to throw in water for half an hour or remind you to take care of the safety of use.
As mentioned in the previous box introduction, A5 has a MIC design, which means that A5 can be used for dialogue. In the Bluetooth connection mode, the speaker's M button can be used to answer (short press) or reject (long press) an incoming call, and double-click to automatically call the last dialed call. There is no noticeable noise or current sound in the voice quality of the call, and it is normal enough to use.
Talk about the sound quality, the price is interested in the bass part, vocals, pop songs like a class is not a big problem, but if you want to achieve HiFi level effect, limited by the hardware design is not realistic. Comment on several representative songs. Device Bluetooth does not support APTX, so it is played with local music.
Take "Sad City" as an example. Although the ring tone is not very crisp, the beginning of a low prelude can be shown. The performance is not too bad and there is no sensation of oppression. The high-frequency part has been suppressed and cannot be fully displayed. In the switching of different musical instruments, relatively smooth transition can be achieved, which is better than expected, and there is no disappointment. The percussion of the drums in Drum Drum is more powerful, and the percussion of drumsticks is dense and boring but not chaotic. On the whole, the bass performance is quite satisfactory.
Taking “Alpine Flowing Water†and “Jasmine Blossoming†as examples, the sound performance is not crisp and the overall performance is relatively flat, but there is no burr or sharp sensation, giving people a feeling of being soft and slightly mellow. Can meet the requirements of less demanding listening. In contrast, the performance of the violin can only say that it is not recommended to audition.
In vocals, the performance of the sound of ventilation is more obvious, and the sound quality is more stable and excellent, and it is suitable for popular songs. Taking "Grandma's Penghu Bay" as an example, the sound of ventilation can be clearly heard, and Zhao Peng's voice performance is comparatively in place, but it is low but not boring. A-Lin's "Imagine You + Toast Song" is one of my favorite songs. The joy of the song can be restored fairly well. It's just that there is no closeness in the performance of the vocal. Rock was selected by Linkin Park's "The Catalyst." Background music and vocals are better separated, there is no mixed feeling of dullness, and some instruments are not shown in detail.
However, it is actually used to see if listening to popular songs is a good choice. For a Bluetooth speaker using a single unit, functional and practical sound quality sufficient for everyday use is sufficient.
Experience summaryWant to talk about the product
1. For A5, it is not easy to view the current playback content without a screen, such as song title, number, station information, and so on.
2. The design of the key under the silicone sleeve causes the silicone sleeve to be turned off every time the switch is turned on. The number of times does not know whether it will affect the sealing performance. If the key is directly designed on the outside, it will be much easier to operate.
3. The USB interface is currently only used as a charging interface, and does not have the function of reading the U disk to play songs. If the external memory card can be directly read and played, the usability will be even greater.
Compared to the market's main HiFi sound quality, aptx-enabled Bluetooth speakers, Polar Night A5 may not have the advantage of competing with them. However, as an outdoor portable Bluetooth speaker, in addition to the necessary waterproof and dustproof, A5's simple design with a variety of playback modes greatly improves the product's application scenario. 4000mAh battery power plus unique flashlight features also make the speaker unique, the sound quality is not too much disappointment, to meet the needs of outdoor use.
