Reasons to purchase In the hands of a Microlab M200 that has been in use for 10 years, a TDK A34, a no-name Bluetooth speaker, and the Sound Bar with Xiaomi's TV is also counted, there are 4 speakers, then X10, IE80, 9500 and PX100 (Yes, the first generation, it has been 10 years), for a fungus is already enough, but always feel a difference in a desktop speaker, think of just make a ring on the line. On-line saying that JBL snails are good, I went to the store to hear, the noise floor is actually so obvious, for I often work in the middle of the night could not bear to. Later, Taobao had a tens of dollars worth of horns. It felt better than many brands of small speakers, and there were no noises in a quiet environment. Of course, the sound quality didn't think too much. The MK and S1000 were actually considered at the beginning, but they were abandoned when they saw the volume. Some time ago I didn't know where to see the evaluation of the S880 (advertisement?). I felt I could try it. Yesterday, Dog East had 999 minus 260 coupons. The rare thing was that there was no increase in price, and it was decided to start. Arrived first looked at the packaging, EDIFIER's unopened tape intact, looks like not 2 hands, the heart of a stone landing. After the opening of the first layer is the first accessories, this cargo actually has an external power supply ... I have a headache Pick up and see 2 white boxes Look at the family portrait This remote control must have its own button battery installed inside the package. In turn, there is a knob which is generally a battery compartment. The main box's backboard (how can it not be rotated automatically? As you watch as the lower cervical movement) Comparing with the old M200, please ignore the messy things behind you. Match with SP4 The remote control is about the size of a mouse. How does it feel? It's not crisp enough, and it feels a bit soft. Look at the details The bottom of the left box is the EDIFIER logo, and the right box is the current mode display. This mode shows that the visual effect is really good, but not dazzling. However, visual inspection is not OLED. Look at the combined position, or can see the gap, work is not good enough. It was time to put on the table, only to find that there was no place to go, so it took more than an hour to clean up the table, repositioning the rows, and so on. This time the most time spent in opening the box was not to unpack but to clean up. In fact, I don't like this appearance. Why do people think it looks good? The monitor is 23 inches. The darkest right is Huayu's NAS. In the corner is Jimei. It can be seen that the box is not small, if it can be smaller. In the beginning, the driver was still out of the way. It was always said that there was no connection. Later it was discovered that it would be connected in USB mode. After everything is ready, connect the computer with USB mode, play it with Foobar, and output it directly to XMOS USB Audio. The sound is quite good. Those adjectives that use bad are too lazy to say it anyway. I like it anyway. After that, try the Fiio X3 coaxial output, because it is directly connected, and the minimum volume is great. Change the time and try Bluetooth again. This is a main-looking HIFI 2.0 speaker, but I do not like this color combination (looks like plastic), just want to find a small volume and sound quality of 2.0, at this point, fairly satisfaction. The sound quality is not good in this regard. Everyone has their own taste. There are many people who hope to have a comparison with the S1000, but I do not have it. However, listening to the fungus for a few hours is quite good. The vocals are comfortable and the bass sounds awkward. In use, a variety of input interfaces, comes with a good quality USB sound card, support Bluetooth aptx, can be considered more convenient. However, if you want to spit the remote control, there is only one button to switch the input source, and you need to switch in order. However, the song switching is not bad, and both Foorbar and Netease Cloud music can be controlled. In general, if you are like me, "I want to find a small but sound quality 2.0", or, plus a "complete function", then this speaker should be able to meet the requirements. If the size is not a problem, but also do not use the built-in DAC, of ​​course, recommended on the MK2 and the like, after all, tried and tested and has a reputation.
