1. Generally, the Bluetooth headset itself does not have a power display function, and if you make another display in the case of a small size and limited power storage, it will inevitably lead to a shorter single use time of the earphone.
2. Bluetooth headset to see how much power can only be seen from the matching mobile phone, but the premise is that the Bluetooth headset must have power display on the mobile phone to display this function (can be seen in the top column of the mobile phone), and not all mobile phones can be realized, it depends on whether the merchant has done this function in some mobile phones when designing this product.
Bluetooth headphones. Bluetooth headset is a small device based on Bluetooth technology, Bluetooth headset is the application of Bluetooth technology to hands-free headphones, so that users can avoid the stumbling of annoying wires, and easily talk in various ways. Bluetooth headsets not only liberate people's hands, but also avoid the pain of hands and necks caused by long-term handheld calls, and can also effectively reduce the harm of electromagnetic waves to the human body.
Since the advent of Bluetooth headsets, Bluetooth headsets have been a good tool for mobile business people to improve efficiency. In 1995, Ericsson was the first to propose the concept of Bluetooth. The Bluetooth specification operates in the microwave frequency band, with a transmission rate of 1m bytes per second, a maximum transmission distance of 10 meters, and can reach 100 meters by increasing the transmission power.
Bluetooth technology is open to the world, with good compatibility on the global scale, and the whole world can be connected by low-cost invisible Bluetooth networks.

Advantages of headphones: When I first got started, I heard that this is an entry-level artifact, maybe the ears are relatively wooden, and I don't think it's particularly brilliant when I use it, but after a long time, I found that there is indeed a mellow feeling. I tried my classmate's recording engineer and tried the magic sound in my ears, but I think that in addition to the heavy bass, it is indeed a good headphone.
Disadvantages: The line is relatively short, and I don't know if it's a quality problem, the arc rubber ring on the top of the head is not strong enough, and sometimes it will fall off a little and clip the hair.
Summary: As the review said, three-frequency balance, at first glance, I think that's what it is, but after a long time, I can't do without it.

Don't be superstitious about Canon's low-end device, which has neither stabilization nor a wide angle. Actually, most small cameras can handle the things you want to shoot. Sony's camera image quality is so poor, and most of these things are shot indoors, so the accuracy of color reproduction and stabilization are important.
The only ones with anti-shake of about 1,000 yuan are Panasonic FP8 and FH1These two are perfectly suitable.
It's better not to use it, wrap it up. Take it out and soak up the sun when you have time!
