Hi all.
The column is available in 3 colors: silver, gold and black. Since the boy will use the column, I opted for gray (if it doesn’t matter to you, then gold can be found for a few dollars cheaper). The parcel was sent with a full track, so information about its movement from China to Belarus is available at the link.
The column is supplied in the original factory packaging, which is a cardboard box. At the time of receipt, it is in a polyethylene package, sealed on all sides. Like the rest of the packaging from Xiaomi, the box does not have a colorful design and an abundance of information. For example, on the lid, apart from the manufacturer's logo, there is nothing: 
Brief information about the object inside is printed on one of the side faces. True, the language here is Chinese. So little is clear at first glance: 
Opening the cover, you can examine the scope of delivery. And here it is simple and uncomplicated: a column, and instructions in Chinese. Not even a charging cable. Xiaomi saved in full. 
But before proceeding to a direct review of the column, I think it would not be superfluous to acquaint you with its characteristics (a free translation from Google, but the essence is clear):
DESCRIPTION:
This is a super portable Bluetooth V4.0 round design that makes it easy to hear whatever is playing anywhere. 2W, which produces sound louder than a normal speaker, giving you an extraordinary sound experience. The CVC6.0 noise reduction system is suitable for office, home, outdoor or party use.
Main characteristics:
1. Bluetooth V4.0 technology, compatible with most Bluetooth-enabled devices, including iPhone 7 Plus, 7, 6S Plus, 6S, 6, 6 Plus, samsung galaxy S6 Edge, S6, etc.
2. Powerful connection range can be up to 5 meters in open area.
3. Built-in microphone for hands-free calling.
4. With a rechargeable lithium battery that provides 4 hours of continuous playback.
5. Support song switch, volume control via your Bluetooth device.
6. Beautifully crafted with aluminum alloy body. speaker Xiaomi Bluetooth is strong and durable.
As for the other Xiaomi products there are no complaints about the quality of workmanship. Everything looks very nice, and from all sides. The aluminum case is qualitatively processed and covered either with paint or spraying. Due to the use of this material, you can not be afraid of the safety of the column even after a fall. Inside, nothing dangles, does not knock, does not roll. 
The column diameter is 5.2 centimeters and the maximum height is 2.5 centimeters. Weight about 60 grams. When I saw her for the first time, I had logical question about how it will sound. The dimensions seem too small.
The base of the column (back side) is rubber. It has a bunch of inscriptions in Chinese, a connector for connecting a charging cable, an on / off button, holes behind which are an information diode and a microphone. 
The rubber prevents the speaker from sliding on the surface and prevents it from "rattling" during sound. But at the same time, it perfectly transmits vibrations from the speaker located inside the speaker to the table. The indicator can glow red and blue: they flash alternately while searching for a device, blue flashes after connection, and red glows during charging. 
There are holes on the side of the case for attaching a cord, so you can wear the speaker even around your neck, even on a bag :) 
The column does not have any buttons (volume control, switching tracks, etc.), all playback audio is controlled from a smartphone or tablet. In addition, the column does not support memory cards, there is no radio in it either. In my opinion, these are its main shortcomings.
Now a little about the charging time and battery capacity. At the time of receipt, the battery was about 50% charged. Hoping to discharge it quickly, the column was launched and played for about 2 hours. Unfortunately, during this time nothing happened and the battery charge indicator displayed on the smartphone screen did not move much. So at the time of connection to charging, the battery in the column was not completely discharged: 
Charging began with a current of 0.35A, which gradually decreased. The whole process took about 45 minutes. After this time, 305 mAh was “poured” into the column. So there is no doubt that the actual battery capacity corresponds to the declared one and is 480 mAh. 
There were no problems with the process of connecting the speaker to the phone. Everything went great the first time. 
Now about the most important and interesting - sound quality. When ordering a column, I was sure that it would play perfectly. Seeing her live, my confidence has lost ground a bit. But after I turned it on, everything fell into place. Despite the fact that the dimensions of the speaker are more than compact, it sounds great. On maximum volume nothing wheezes, does not crack (but this is when listening to pop :)). It sounds much louder than a phone and certainly not quieter than bulkier speakers from other manufacturers. And on the table on which the speaker lay, vibration from low-frequency sounds was even transmitted, which no one expected.
Summing up everything that was written here, I will say that I personally liked the purchase. It is well-made, has a small price and, most importantly, it sounds great for its size. I hope its future owner will also like it (even though it does not have a radio and support for memory cards).
That's all. Thank you for your attention and your time.
I plan to buy +4 Add to favorites Liked the review +11 +22What you will not find in a wide range of products of the Chinese company Xiaomi. It seems that it has penetrated into all areas of electronics. Do not bypass the sound - portable speaker Xiaomi Mi Bluetooth Speaker managed to fall in love with a lot of people.
Pure sound
In a small aluminum case, Chinese engineers hid two 36 mm emitters with a total power of 6 watts. And the "baby" sounded with clear upper and middle frequencies with a pleasant and elastic bass. Moreover, with an increase in volume, the sound quality does not deteriorate, allowing you to comfortably listen to your favorite tracks on the street.
Broadcast
Music is broadcast either from a mobile gadget connected to the speaker via wireless connection, or from a microSD memory card, the slot for which is located on the left side of the portable player. To pair with a smartphone, just turn on the Bluetooth module on both devices.
Control
The right side of the speaker is occupied by 4 control keys: a large “Play / Pause” button framed by a light indicator, volume control and track rewind buttons, as well as a voice notification key and unbinding from the Bluetooth network. The sound of the remaining battery charge and other notifications is, unfortunately, exclusively in Chinese.
Long autonomy
Xiaomi Mi Bluetooth Speaker can work on a single charge of a 1500 mAh battery for about 8 hours(at medium volume). Fully charging the battery takes about 2 hours. To replenish energy reserves, you need to use a cable with a microUSB connector, which for some reason the manufacturer did not take care of in the package. But he carefully put a fabric storage case into the box with the device.
Companion
The model is available in various color variations that can satisfy the tastes of both the beautiful and the strong half of humanity. In addition, in comparison with a fellow Xiaomi Mini Square Box, it has much more functionality. If you do not understand your life without music, Xiaomi Mi Bluetooth Speaker will take on the role of a faithful companion in playing your favorite tracks in all suitable places (at home, on the street, on a camping trip, etc.).
Among the reproaches of the editorial board, one can meet, at first glance, a contradictory claim. Some reproach for vinyl tables worth a million, others are annoyed by multimedia novelties. Ideally, the magazine should tinker with some sort of weighted average price range and don't look where you shouldn't. How do I see this process when the main system has been assembled for a long time?
The development of D-class amplifiers and DSP processors marked the renaissance of compact audio. In general, I like to scale audio tasks. Why can't you listen to a Bluetooth speaker after some monstrous DAC? Each form factor is interesting to find its pearl. For example, the model considered here provided an almost esoteric experience in a twilight forest by a lake. First, the mixtape Tropic of Cancer played, then the Latvian wave of the early 90s, and the evening was summed up by the Ensemble of Christ the Savior and Mother Earth Cheese. Ok, the reader may not care about my music selection, but would it be right for the outdoors to drag any column?
