sequence: Thanks again to Zhang Da Ma for giving me this opportunity. I would like to take this opportunity to also pay tribute to everyone in the old age here. I wish you a happy New Year and all the best. When I saw the text message, my heart was really embarrassed because I was afraid that I could not write it well as a fungus, but I also thank Zhang Aunt for letting me never know it until I knew it. Therefore, I still accepted it. We shouldn’t be surprised if we don’t write well here. Unpacking: This time due to the New Year, arrived express delivery, Zhang Aunt chose to express the boss inside, indicating the intentions of Zhang Aunt. Open The poor side did not shoot, and the blank side Throw away my film product description: Above Product model: W2090BT, from the out of the box to see this time for the dazzling black, the contents of the box I will not be introduced one by one, say "super comfort", personal feeling is that the corresponding eight pairs of earplugs, how are you think. The right side is a brief introduction, out of the box for magnet adsorption. The above is a design that facilitates suspension, and how many can still see the design's intentions. The back full of text, you see it is offensive. (It's no wonder that learning is not good) It is also a very simple design with security code and advertising 4 sets of ear plugs, a headset, a take-up box. Look at the box first. English is not good. It does not help translation. Open place, easy to open. The desiccant was thrown, and the rest was the entire contents of the box. Again The cloth inside the box feels so The protagonist appears. Looks so comfortable. It's not good to shoot yourself. Find a picture to make up. Is there a daring hurry? The specific use of these buttons, etc., will be described in detail later. One of the details above should be mentioned. The plus and minus buttons are different, and they are very intimate. This is the charging hole, you can also see the microphone hole, where we have to consider different things, where the battery installed. Such a small battery is also a core component, and the contents of the specific battery will be introduced next. This thing I feel a bit redundant, this thing is glue, personal feeling it put a line into the need to use a lot of effort, it takes a lot of effort, relatively new pain line. Packing List Headphone*1, Audio Cable*1, Micro USB Data Charging Cable*1, Storage Bag*1, Ear Plug*8 Features: Light As a sports headset, you still need to consider how the headset does not come off in the case of doing great sports. The total amount is of course the first step. It's really light to get it, but it's not weighed. Simple button It is true that there are only a few simple buttons with only three buttons. This is also difficult and difficult to use! To be honest this stop button is enough for me. Bluetooth This headset is using the Bluetooth 4.1 version, but also Baidu about the Bluetooth version of the problem, the result is a 4.1-bit 4.0 software upgrade, the difference is that for 4.2 does not have to upgrade the firmware, of course, the transmission speed is not 4.2 fast, the other is not different . However, there are two points that need to be addressed. One: The transmission distance is not as good as the publicity. If I actually use it, I don't feel like it is 10 meters away. I may need to test the environment (such as empty space), but this is just the actual situation. II: The connection effect is very good. This point is a bit deep to me. The effect of the bracelet is not good, and the headset is relatively effective. Electricity Sports headphones, or to say the power, the official introduction of 8 hours of long use, after a few days of personal use, it will use a day, the specific time and did not test, charging time official introduction 2 hours, the actual charge of about 1 and a half hour. The specific battery capacity can not be tested, but the overall performance in terms of power is also good. waterproof This does not count as a highlight, but a feature, IPX4 waterproof rating, as shown below. In other words, do not rinse with water, but as a manufacturer, I think there will be a bit of a conservative rating, personal feeling may reach the IPX5 level (do not pay for damage) H After looking at the official introduction, there was a drag and drop feature and try it out. Well, I can't figure it out. Take a look at the manual, and for a moment I still haven't done it. The original default one-two is closed. I need to hold the stop key and the next key for 4 seconds at the same time. After successful opening, two mobile phones are connected simultaneously. When two mobile phones are tested, they will only ring one mobile phone at the same time when the music is played. The first ring will ring, and the music of another mobile phone will play after the music is paused. It is not played at the same time. Here also mentions the issue of backlinks. The problem with the smartband is to connect back, but the headset's backlinking function is relatively strong and the backlinking works well. Colorful The color is reflected in two aspects, one is color, red, black, and white, and then the painted ear shell is very much liked. Here I feel that this headset is a bright spot, a multi-color choice and very stylish, very popular with young people. Sound quality This problem is not too much to talk about for two reasons. One is their own fungus, poor ability to distinguish sound quality. The second is also looking for a few headphones compared to what is not particularly ideal. In the spirit of Zhang Ama, I will tell you about the situation. Contrast headphones 1. SOMIC SC421 Ear In-Ear 2. Sony (SONY) MDR-XB650BT Headset Compared with the first soprano, bass and midrange, the sonic quality of Somic was slightly better, and it did not feel much better. However, after all, this is the difference between Bluetooth and cable. Nothing compares with the second weighted bass. I don't feel like a price. I don't think it's comparable. Basically I don't have to think about it. to sum up: Look good, multi-color choice, fashion, battery life is no problem, the phone can promptly see when the Bluetooth power is low, it will prompt, sound quality performance in general. As a Bluetooth sports headset, the overall performance is still quite good, cost-effective, the ideal price of 220 yuan. But still need to remind, sports and music are good, but still pay attention to safety. Note: The above point of view only represents personal opinions. Improper points are also expected to be pointed out.
