I bring to your attention an overview of an interesting device - a bluetooth speaker, which can also be a card reader and a usb sound card, a bluetooth headset (free hands).
For the lazy, a short summary: I liked the sound very much; as an external usb sound card, bluetooth, connection via audio wire, mp3 from a card - everything works; the card reader is working, but very slow; Free hands works, but microphone sensitivity is low.
In general, I liked the device, especially the sound - I recommend it for purchase.
Well, now for the details ...
Foreword:
I was looking for the cheapest bluetooth speaker offline. I wanted to output the sound from the android TV box through it, so that I could hear calls on Skype when the TV is turned off, the sound does not go through it, respectively.
Alas, I didn't find anything decent cheaper than 2-3 thousand. And this is in Moscow ... maybe it was worth driving to the radio market, I would probably find there some kind of Chinese analogue of the monitored column at a price of 1300-1500 rubles. But I was frankly lazy and then I bought ordinary wired speakers for 600 rubles. And here, by the way, came a coupon from a panda for $ 25 for a review of the phone. For him, having paid a couple of bucks and ordered this column.
So, let's begin.
This device came in a rather nice box made of thick cardboard with magnetic snaps. The box was immediately taken away by his wife to store all the small things.
The column itself was found inside the box, pasted over protective film, 2 wires (usb-mini usb and audio 3.5 jack) and detailed instructions on English language.

Appearance
At the top there is a metal speaker mesh, in the center of the mesh there is an insert with an eagle.
The speaker is declared 5W, it was not possible to check it, I could not get to it: (The case is metal painted in one of 3 colors. The lower part is plastic. It has connectors on the side - miniUSB for charging and connecting to a computer, 3.5 minijack for wired connection to a sound source, a microSD card reader and 2 LEDs for status indication.
Now we turn the column over and see the control buttons at the bottom - the on / off button in the center. Around it are play / pause and answer buttons using the speaker microphone when connected to the phone. Well, 2 buttons ± - short press - scroll through tracks, long press - change the volume.
The buttons are pressed clearly. Because the main purpose is passive music reproduction, the location of the buttons does not cause any particular inconvenience. A silicone ring is located around the buttons, designed to enhance the contact of the speaker with the surface on which it stands. The fact is that the column uses the system low frequency resonance which uses the surface on which the speaker stands to improve bass transmission. A lot of debris and dust sticks to this gum, but it can be cleaned without question with a damp cloth.
We include
When turned on, a short pleasant melody is played. The same sounds are emitted when connected to a computer, inserting a memory card, and in some other cases. The main disadvantage, I would say, is the impossibility of adjusting their volume, it's okay during the day, but quite loud in the evening.
Work declared within 4 hours, but to be honest I did not check
Sound
The main thing in a speaker is sound. My hearing is not musical. But I really liked the way it sounds. The sound turned out to be much better than I expected from a mono speaker. According to my feelings, it is "deep" and "juicy". Placing the speaker on a suitable surface dramatically improves bass performance. The surface of a wooden table works best. By the way, at full volume, the mouse cursor, lying on the same table, starts jumping across the screen from vibration. However, if you make it quieter, then there is no interference
About volume. The volume is good. It is quite sufficient for the room, it yells loudly. I have not tried it on the street, but there are suspicions that the volume will not be enough on a noisy barbecue. This speaker is clearly louder and more suitable for a noisy street.
Below there will be a video where you can try to evaluate the sound.
Connections
Unusual, for speaker Card reader, USB sound device, USB microphone, some kind of player.
The "USB audio device" is pretty cool - in fact, it is an external sound card connected via USB. This means that by connecting the speaker to your computer, you can play sound through it, even if your computer does not have sound card, what else is found on work computers in offices.
Defined as a stereo device.
Column is defined as standard USB audio device and does not require special drivers. Compatibility is declared starting with win98 as well as Mac OS and Android.
Well, I do not know, it worked in win7 without question, with android the same way.
By the way, if you have a laptop with an inconvenient external connection of speakers in front or on the side, where they interfere e.g. mouse then you can use this option as an alternative. Again, one wire at a time and sound and charging.
The second usable device, which was detected when connected to a computer, is a card reader.
Well, he upset, consider that he was purely so. The operating speed is very slow. Below is a comparison with a conventional MicroSD-USB adapter.
MicroSD-USB adapter to the same memory card
2) Audio cable connection
Well, everything is standard here, a standard 3.5 audio jack, a connection cable is included. By the way, the sound through the wire is louder than through the bluetooth.
Suitable for increasing the volume of laptops, phones, etc.
3) bluetooth
Here, too, everything is standard. Bluetooth 2.0. Supports profile music and profile conversation.
I tried to talk using the microphone built into the speaker, connecting it as a headset to the phone. The interlocutor can be heard normally in the column, but you can hear me only if you hold the hole, where the microphone is, 2-3 cm near the mouth. Perhaps it will help to pick out this hole more, it is much smaller than the microphone. or you can re-solder the microphone to a new one if you need this feature. I remember this advice (about soldering the microphone and business) I met in the review of some phone, but what did you really want from a mini speaker
4) Connect to android (TV Box with OTG function)
For some reason, the microphone was not detected (sound input), but how the external speaker was fully determined and works (sound output)
5) Autonomous work
We connect the memory card and the playback of the found mp3 starts. Scrolling - forward / backward, there is no inside the track. When turned on again, it continues where it left off. Support for cards up to 64Gb is declared. I got a max size card - 16GB. 32 and 64 chewed for a long time and did not go, maybe there were a lot of files or somehow it was necessary to format it, I don’t know - I didn’t understand.
We disassemble
We tear off the rubber band, unscrew the 3 screws ...
Unfortunately, it was not possible to reach the speaker.
Video

Outcomes
Excellent sound quality
+ Low-frequency resonance system
+ External audio device for various devices
+ Workmanship
Slow card reader
- unregulated, loud enough sound for switching on / connecting
Would I buy this speaker again now at full price? I think yes. I really liked the sound, and offline I was ready to pay a large amount.
Hello! A short essay tells about a compact player in the shape of a minion figurine from the cartoon Despicable Me 2. The player was purchased from Aurabuy store along with other needs and a $ 20 coupon for winning the review contest on this site. Thanks everyone :). More details ...I'll start by packing the parcel, packed it - great, in a bubble wrap and a cardboard box, securing it with yellow tape. However, as always - well done.
I also note that this time the order was processed longer than usual, since one of the selected items was not in stock. The store's support responded to my letters in the second half of the day, in the traditional Chinese style :). As a result of negotiations, the replacement of the missing product was promptly selected and the order was sent by Singapore post, delivery took 20 days.
Player packaging:
Cardboard box with dimensions: 8.5 cm x 14.7 cm x 10 cm.
The cardboard is thin and dense, the inside is brown, and the outside is a glossy surface, decorated with: colorful illustrations of cartoon characters, a photo of the player itself, instructions for use and technical characteristics products. All sides of the box are involved in conveying useful information about the product, very good packaging, I think. 
Appearance:
The player has a name - mini speaker XC-01, in my humble opinion, is a multifunctional device, because:
1. Looks beautiful like a toy
2. Can work as a player (with flash drives and cards)
3. There is a radio function (FM band)
4. There is a mode of operation as a loudspeaker (line in).
Dimensions:
Height: 12.5 cm
Diameter: 6cm
Weight: 200 gr

Bottom: 
The arms, legs and hairstyle are movable, you can rotate them 360 °, in addition, you can also twist your palms.
Gloves, hairs, legs, glasses holder and pants are made of a material resembling hard rubber, they are attached separately from the minion's body, on top. The body and all other parts are plastic. The plastic is smooth and strong. There is no bad smell from recycled plastics. The workmanship of everything is very good.
Contents of delivery:
Player-minion 1 piece
USB-MINI USB cable (50 cm) 1 piece
Mini jack cord 3.5 mm - MINI USB (50 cm) 1 piece 
Operating principle:
1. Connect the required device to the minion, in accordance with the available connectors 
2. Place the player on a flat surface, taking into account that the sound will be broadcast from the flower-shaped holes located in the back of the minion. 
3. Switch on the device using the on / off switch. The minion will happily greet its owner, and the diode will festively illuminate it with a blue light. 
4. All controls are concentrated on the black wheel / button. Having studied its work, you can select the desired mode, and then enjoy listening and admire the flashing blue diode.
Description of wheel / button operation
Mode selection:
Press lightly on the wheel, and while holding it in this position push it up or down.
Modes are switched in turn: FM / USB / TF / Line in. Select the one you need most, release the wheel.
The player remembers the last played position and the operating mode.
Volume control:
Slightly turn the wheel up or down (quieter or louder, respectively), holding it in the extreme position, set the required volume level.
Switching between tracks, searching for radio:
Briefly turning the wheel up or down, fast forward or rewind (search for radio stations forward or backward). A short press on the wheel toggles the play / pause mode.
The antenna for the radio, apparently, is inside, since by changing the location of the minion, you can expand the number of received radio stations and affect the quality of their sound.
Output:
Excellent player / receiver in my opinion.
Pros:
+ First, very beautiful
+ Secondly, good sound quality, I dare say - clean sound. When listening to files with a bitrate of 128 to 320 kbps, a difference in sound is noticeable (the most optimal for clear sound is an average volume level, at minimum and maximum there are distortions)
+ Thirdly, it is capable of producing a very loud sound, it was a surprise to me
+ Fourth, long operating time from the built-in battery (arrived charged, already worked - radio and memory card, more than 9 hours without recharging)
+ Fifthly, there is a memory for operating modes
And most importantly, no one has such a minion.
Minuses:
Blue diode
