When we go out to play, we always take a lot of equipment, such as speakers, such as flashlights, such as power packs, and so on. There are many things that are not convenient to carry. It's easy to be in a hurry when using them, but these devices are indispensable for traveling, so it's really difficult to choose between them. Recently, the author found a good Bluetooth speaker, which perfectly meets the needs of my daily travel. This device comes from the polar night. For the polar night, the author's more understanding comes from smart hosts such as the polar night T3, T5, T7 series, such as the mini host T300, etc. The Bluetooth speaker from the polar night is the first time that the author has seen it. Of course, the author is more looking forward to its multi-function.

The polar night A5 outdoor sports Bluetooth speaker is packaged with environmentally friendly paper and printed with the appearance and basic technical parameters of the product.

In terms of product accessories, except for Polar Night A5, Polar Night only provides a data line for power supply and a simple instruction manual.

For Bluetooth speakers, it is necessary to read the instructions carefully.

In terms of accessories, the product is charged by MicroUSB, so a relatively short data cable is provided. As far as the author is concerned, if only one accessory can be provided, the author would prefer to provide 3.5mm audio pair wiring, because after all, the possibility of the lack of such data cable in the home is very low. Therefore, the author hopes that later manufacturers can configure the combination of data cable and audio cable as standard to facilitate users' use. Similarly, for the data cable, the author believes that the data cable provided by the manufacturer is slightly short, which is inconvenient to use. On the other hand, the FM reception function of the speaker makes it easier to receive FM signals when the data cable is longer.

The product I experienced this time is the grass green version. The product is made of black PC material, and the inside of the speaker is wrapped with grass green rubber pads. The logo of Polar Night is printed on one side of the product.

The two sides of the rubber pad are designed with special anti-skid particles, which have a very good anti-skid effect and feel very comfortable.

In terms of keys, it is very similar to an ordinary Bluetooth speaker. On the left side of the speaker, there are mode selection keys "M", volume keys "+" and "-", and on the right side is the power button of the flashlight.

As an outdoor speaker, waterproof function is very important. In order to achieve good waterproof effect, the charging port, power switch, TF card interface and audio input port are all designed under the rubber pad. The small round hole reserved on the left side of the rubber pad is the A5 audio input hole for answering calls.

meet The back of the mouth is located at the diaphragm air outlet of the speaker and the hook. Through the hook, the speaker can be easily hung on the bike, but to the surprise of the author, A5 does not provide a hook. Because the author does not have a suitable hook, so it is impossible to use the hook. The hook is made of plastic material, and the hook is fixed with copper threads. If the buckle is not added, the author is worried that it will be dirty. After it is hung, a piece will protrude, which is unnecessary when it is not needed in daily life. Therefore, it is recommended that the later products consider leaving a special rope hole on the speaker body.

The top of the speaker is a loudspeaker hole, and the bottom is a flashlight. One of the functions that the author likes very much about the A5 Bluetooth speaker is the flashlight function.

The charging current of the Polar Night A5 Bluetooth speaker is as high as 850mA, and the charging time is about 4-5 hours, which is consistent with the performance of the Polar Night A5 battery capacity of 4000mAh. As for the explanation of Polar Night, the continuous playing of music can reach more than 20 hours, but the author has not used it for such a long time. The author has played it for more than eight hours, which is completely satisfying for the author's daily use.

As an outdoor device, the Polar Night A5 can also be used as a temporary standby power supply to charge mobile phones. Due to its battery capacity, it can be used as a standby power supply.

The flashlight function of the Bluetooth speaker is still very useful. The A5 uses 1W LED beads, which is good in terms of brightness, but there is still a big gap between it and the glare flashlight. In addition, due to the author's work habits, the company's standard is that the flashlight at one meter has no light spot and is relatively standard round. As far as the author's personal habits are concerned, obviously the flashlight of Polar Night A5 is not too standard. But daily use is enough. Similar to the daily strong light flashlight, A5 provides three levels of strong light, weak light and SOS flash function.

Compared with ordinary radios, the FM function of the speaker is not strong in signal reception. The author can only receive a broadcast radio station at home without external wiring. After the charging line is connected to the charging port, more than eight radio stations can be clearly received. The radio with side feedback of Polar Night A5 must use an external antenna to achieve good results.

The A5 Bluetooth phone function is relatively convenient to use. The M key can be used to answer, call back and reject calls. The actual experience of the author shows that the call quality is very good. The call is clear without noise, and it is very convenient to use. However, the author is not used to answering the phone with a speaker, so this function is not very important for the author.

In terms of music playing, A5 provides three functions: TF card, audio input and Bluetooth playing, which users can choose to use according to their needs.

Of course, as an outdoor Bluetooth speaker, the Bluetooth playback function of the Polar Night A5 needs special attention. In my personal opinion, the playing quality of the music of the Polar Night A5 can only be regarded as average. If you like to listen to popular songs, it is OK, but its performance in bass is average. The author likes pure music such as Mystery Park very much. He likes to listen quietly when he is alone. The sound field performance of polar night is good. However, polar night is not suitable for listening to music at close range, and the speaker has a little noise. In addition, in my personal opinion, the polar night A5 sounds more delicious when placed flat. For a speaker with various functions and a price of less than 100 yuan, it is a bit too demanding for sound quality.

Summary

The polar night A5 outdoor sports Bluetooth speaker has waterproof and dust-proof functions, which is very convenient for outdoor use. At the same time, because of the built-in high-definition microphone, it can realize Bluetooth wireless calls. In addition to the Bluetooth play function, it also has audio input and TF card play functions. For users who like radio, it can also be temporarily used as FM radio. The author likes the A5 flashlight function very much. With it, there is no need to carry an extra strong flashlight. If you like to go out and play, you might as well try it.
