Because I wanted to participate in a local marathon in July, I decided to practice again. The first thing I had to solve was the problem of equipment. Because I needed to adjust my posture by understanding my pace, and I didn't like to wear a watch, I decided to buy it. Bluetooth headsets are resolved through the motion app voice prompts. The ensuing question is what kind of Bluetooth headset I need in the end. Think about Bluetooth headset that meets my needs at least need to have the following characteristics:
1. Longer battery life: Because it is a whole horse to run, it should have at least 5 hours of battery life, taking into account the impact of battery attenuation in the future, it is best to nominally more than 6 hours.
2. Higher waterproof rating: Although I only need to run without headphones for swimming, taking into account the amount of training for a single 30km, it will inevitably cause a lot of sweat, so the waterproof rating is not lower than the IP57 level (also precisely because of this Pass pass beats x).
3. No or almost no stethoscope effect: This is believed to be easy to understand if the stethoscope effect has been a nightmare for a long time running.
4. More comfortable to wear: Maybe my ear structure is a little more special. I haven't been able to wear ear for 2 hours without earplugs. It's not painful, including the Sony sbh70 I bought before, so I At the beginning, I didn't hope to buy headphones that didn't hurt me. I just wanted to be comfortable.
5. With the communication function, the best call noise reduction can be better: because a training can take 3-4 hours, the middle will inevitably have to answer the phone, and after running into the state, it is not willing to do too much action, so it can directly answer Best of all, the Sony sbh70 that I used before had communication capabilities, but there was no noise reduction. According to people who answered the phone when they were on the run outside, they all talked about the wind, but I didn’t notice any laps to notice The headset that meets the above 4 points has this feature, so it cannot be forced.
After selecting the requirements, the selection is much simpler. The first thing I think of is the Sony sbh70 I have used. Although it is not comfortable to wear, the battery life is about 5 hours, but other aspects are still satisfactory, but there is a big problem. When I purchased sbh70 in 15 years, I had a factory bag and sold it for only 278. Now Taobao is boxed, at least 450 or more, and spends so much money on an old one than on a year and a half ago. Headphones I was really uncomfortable, can only give up (feeling that various manufacturers still do not pay attention to Bluetooth sports headphones, update speed is too slow).
Followed by Plantronics backbeat fit, nominal 8 hours battery life, IP57 waterproof and have the call function to basically meet my needs, so I decided to buy, but just to catch up with and generation of big sale, hesitation It is the purchase of a cheaper generation (Jingdong several activity prices are around 350) or to buy a much more expensive second generation, and found a few laps as if there really is no second-generation evaluation, but fortunately, Taobao and Meiya's There are just a few people in the purchase evaluation who purchased the first and second generation at the same time. Through their comparison, they learned about the differences (all are network summaries for reference only):
1. In addition to canceling a generation of gifted armpacks, the second generation has only upgraded places and no castration relative to the first generation.
2. Second-generation sound quality, workmanship, materials better than a generation.
3. The second generation has the function of prompting the remaining usage time by the power-on voice.
4. It is more convenient for the second generation to switch different Bluetooth devices (one generation needs to be paired again).
5. Second generation with fast charge function
(It needs to be emphasized that the "generation" and "second generation" of this article are only used to distinguish between them. The Plantag official doesn't say this, and the names are all backbeat fits.)
After the comparison, because they are all upgraded, plus individuals buying electronic products have the habit of buying new ones instead of buying old ones, so Taobao chose a relatively cheaper one to buy the second generation, and then bargain with the store again. With the arrival of gold coins, the final cost is 621.94.
Like the first generation, the second generation of packaging is the same color as the headphones themselves.
On the back of the box, the bottom made for fear of using Android is not happy ~ 
Unlike the generation of Malaysian production, the second generation became the production of Mexico.
After opening, it is the back of a sexy lady and the headphone body. It can be seen that the headset itself is very soft, which is also the guarantee of comfort.
In addition to the body also comes with a usb line, but the work is very general, the wire is hard, there is a sense of the cottage, the official pricing given to Plantronics is 998, this price of the headset should not appear this wire, ah, it is estimated that Mexican workers are not To understand the Chinese language, there are two complicated manuals and no brief manuals.
Incidentally, this earplug sleeve has bright eyes, I first saw this color thought it was just a protective cover, after a closer look only to find that it is fixed to the headset, it can adjust up and down 20 °, can basically find their own Angle
experience feelings
Immediately after pairing a good headset, the mobile phone immediately prompts you to download the relevant app. It's very confusing when you go down. There is only one function for the two apps. One is to look for the Bluetooth headset and the other is to upgrade the firmware. You can select Putonghua as the headset prompt when upgrading. The main function of the sound is to give you the remaining power
Wearing the glasses as shown in the picture, although it looks very easy to fall out, but I jumped violently for 2 minutes are very stable, there is no stethoscope effect, so do not worry about daily exercise, and wearing comfort is better than sbh70 Many times, I was wearing only 3 hours of continuous wear and I was only slightly discomforted. This was a pleasant surprise for me, and the endurance time was basically the same as the official announcement.
Finally Tucao about the seller comes with two kinds of gifts, headset headset plug does not go in and the arm bag work touching
Overall, this headset is still satisfied with me, high battery life, high waterproof rating, good comfort is the most important feature of my Bluetooth sports headset (my personal feelings), and the backbeat fit is exactly the same, complete I met my needs, but I just looked at Taobao's cheapest second generation has risen to a small 700, and the cost has dropped further, unless the real budget is sufficient, or pay attention to Jingdong's next event to buy a ~
