Aunt's above about the headset has been more and more out of the box, I feel this time from some use to talk about this headset.
Purchase link
Why buy a Bluetooth headsetThe first time I used the Bluetooth headset, I used Sennheiser's cx880 before, and the line was killed by the Totoro inside the family. Head-mounted bought akg k550. The line of helplessness is really too long. Each time I go to the table, I feel that the entire desk is line, and the headset is really too big. It is particularly hot in summer and stupid to go out on the street. Later, it took a while for the iPhone's original headset. After Apple 7 came out, the married woman bought an Apple 7, but because he couldn't plug in the computer, he got the idea of ​​buying a Bluetooth headset.
About appearance

Button details
Button details, including a volume increase and decrease button, a button to answer the phone, a charging port.
About sound quality
The headset supports both Bluetooth and wired connection. Seriously, when we first started using Bluetooth, we found that the sound quality was not very good. When you listen to hebe, you don't want to think of me. It always feels like it's masked sound. It's boring and it's not very transparent. The sound of exercise also feels not strong enough. Feeling less than Apple's wired headphones before. Even once I had the urge to return. However, after comparing my coworkers' powerbeats, I feel that it is possible that Bluetooth headsets will do the same.
Fortunately, the 750bt provides a wired connection mode. Even after the line is connected, it feels like the stars in the sky are bright. The sound of the original bad news suddenly widened. It feels like the difference between the previous cx880 is not big, and it feels like listening to comparative data.
I generally listen to more pop music, and the vocal aspect is still quite comfortable. Let's go to judge the more metaphysical things.
About commuting and going to workThe soundproofing effect of the earphones is good, and in the case of music, basically the surrounding sounds can be ignored, and the situation that others call me may not be heard. When I'm at work, I can hardly hear other sounds when I put the headphones on the music. It's easier to immerse myself.
About sports Before I wanted to buy a Bluetooth headset, I felt I could barely use it as a sports headset. However, after use, it was found that this headset cannot be used for running. The design of the collar makes it easy to run into the clavicle and it feels sticky after sweating. After giving it up, it is abandoned. It's not a sports headset or a sport headset.
As a call headset, the voice of the other party is definitely still very clear, but after a relatively thick winter wear, if the headset is wrapped in clothes, it is not easy to hear the other party to hear clearly, which is quite terrible.
About life The official standard statement is 7.5 hours, but as a daily use (not too severe, but also used more, it should be able to represent the majority of people's use of it), basically able to meet the two-day impulse. Until now, there has been no use of electricity.
After I bought the headset, I was described as gay, but for the moment I thought I was praising me. Ha ha ha, but this color is indeed a show, from the storage bag to the headphones are very showy green. 
to sum up
The style is beautiful, the sound quality is acceptable, and it is not sporty. It is not a regret to buy it.
