At the moment, I listened for several days and I didn't know how to open it. I felt that the sound field had been opened a lot. I felt that the performance was quite good at this price point.

Behind the test, there is a telephone answering function, corrected
Something was sent by a friend jokingly last week. I did not expect to send it.
Therefore, at the weekend, it was just enough to play it. By the way, I took a box out of the sun for reference.
JD searched, quite expensive, 899 one.
The packaging is designed to look pretty
At that time, I saw that Bluetooth 4.0 and APTX support sound quality should be not bad. 
List of all accessories. 
Appearance, this counts Hermes yellow? However, the appearance is quite unique, but also considered a fashionable style. 
The front surface of the network, vaguely able to see the audio unit inside. 
LOGO position, but fortunately not in the middle, or to estimate the ugly death. 
The back is also a mesh, vaguely see a passive audio unit. 
IO port, only the power supply with 3.5MM input. 
Bottom non-slip rubber. 
The top design is also very simple, that is, metal brushed body with keys 
The other part is this decorative board that looks like a leather effect, but it is actually a plastic. If it is real leather, it's just fine. 
Straight connection is very simple, no nonsense. 
Focus on the next audio and use it
The Bluetooth signal is normal and there is no problem from the wall between the basic common room. It is easy to break the signal after two walls or load-bearing walls.
Life time to see the official introduction of 4.5K milliamps, usually always plugged in, so the actual life is not very different for me, but the weekend out of the square with an afternoon to go home basically still have electricity.
Listening to see the official introduction of the 2+2+2 cell structure, the basic is the active audio + passive audio unit, the specific did not disassemble, so I do not know how the structure inside, but probably must have read the 2+N structure, Therefore, the sound quality of the Bluetooth box is better than that of the normal 2 unit, and the N is generally used to strengthen the low frequency unit of the Bluetooth box.
What is the actual effect? Really count it okay, low-frequency gain is quite obvious, a lot stronger than the 3.4 hundred ordinary box, a sense of a stronger range, but it is a bit loose, but after all, a small box, can not ask too much.
The high-frequency part has always been the strength of the Bluetooth small box, this box in the high-frequency performance is also OK, resolving power, but a bit toothy.
Actually used a D100 recording Dafa for reference.
The overall use feels okay
The volume level, personally feel that it is fully enough, but of course, PK can not square dance aunt.
In addition, the decorative part can be made of real leather, and the function is more, such as telephone answering or TF direct reading and the like.
Price 899 Feeling expensive, but anyway, someone else sent
