Bluetooth headsets are becoming a product that people are increasingly favored because it can solve the dangers of the phone we started answering, but also let us not have to be wrapped around an annoying headphone cable, but do you know how to choose a Bluetooth headset?
On-demand optional Bluetooth headset
According to a salesperson of a mall's Bluetooth headset counters, Bluetooth headsets are based on the use of Bluetooth technology in hands-free headsets, allowing users to avoid the annoyance of the wires and easily communicate in a variety of ways. â€œNow there are more and more car owners. Answering the phone during driving is a very dangerous thing. With the continuous improvement of the publicâ€™s safety awareness, people like to wear a Bluetooth headset to facilitate the call and also ensure the safety of driving. In addition, many citizens like to wear Bluetooth headsets to listen to music, the current Bluetooth headset sales are very optimistic.â€ Sales staff said.
It is understood that the Bluetooth headset on the market is roughly divided into two types, a monaural Bluetooth headset and a stereo Bluetooth headset. Monaural bluetooth headsets are mostly wireless compact styles that can be worn directly on the ear. The main function is to answer and hang up the call for volume adjustment. In addition to answering hang-up calls, stereo Bluetooth headsets can listen directly to music and have good sound quality.
Sales staff suggested that the public should choose Bluetooth headset according to different needs. Business people need to answer the phone frequently, so they should choose a Bluetooth headset with good call quality and long standby time. Music lovers who wear Bluetooth headsets must choose stereo Bluetooth headsets with high quality and high quality. "Consumers may be confused by some concepts when buying Bluetooth headsets. Generally speaking, stereo headphones are not necessarily stereo headphones; stereo headphones must be dual-channel (multi-channel) headphones. To understand this little knowledge, you can Better choose the Bluetooth headset that suits you,â€ said the salesperson.
Bluetooth headset to be compatible with mobile phones
It is understood that Bluetooth headset specifications, there are HeadsetPro-file (HSP), HandfreeProfile (HFP) and A2DP three specifications. The HSP provides the basic functions required for communication between a mobile phone (mobile phone) and a headset. HandfreeProfile (HFP) adds some extensions to the HeadsetPro- file (HSP). A2DP (Advanced Audio Transmission Specification) allows transmission of stereo audio signals.
"Because of the large number of mobile phones and headsets, the most troublesome consumer is the compatibility issue between mobile phones and Bluetooth headsets. Consumers must first study what kind of specifications their phones support before purchasing, and then find suitable pairs of Bluetooth headsets. Among them, the HFP-formatted Bluetooth headset supports the complete function of the mobile phone, and the consumer can simultaneously operate the mobile phone to set the hands-free option such as redialing, call reservation, and incoming call rejection on the headset, the salesman said.
When consumers purchase Bluetooth products, they often see Bluetooth 1.1, 1.2, 2.0, etc. The numbers represent different specifications. The higher the number, the newer the version. The new version can better overcome the noise interference, and all the latest Bluetooth versions are designed to be backward compatible with all previous versions. The 2.0 version of the device and the 1.1 version can also be freely connected. The compatibility of 3.0 is relatively strong and is a mature technology. Battery life is also increasing because of technological advancement. Consumers should measure prices and demand when they buy.
Bluetooth headset charging 2 hours best
The Bluetooth headset is a small electrical device. When it is used for the first time, try to charge the headset for 2-4 hours. After that, charge it for 2 hours. It is better not to exceed 4 hours. Some consumers think that it takes 24 hours to charge for the first time. This is unfounded, and overcharging will affect the battery life of Bluetooth headsets.
It is understood that the Bluetooth headset transmission distance has nothing to do with the Bluetooth version, but depends on the Bluetooth technology PowerClass. Most mobile phones and mobile devices use the PowerClass2. The standard transmission distance is 10 meters. The upgraded PowerClass1 increases the transmission distance to 100 meters. â€œIn practical use, the distance between the mobile phone and the Bluetooth headset is proportional to the noise of the call. Therefore, try not to keep the Bluetooth headset away from the mobile phone when using it. If there is no big obstacle in the middle, the transmission quality is good within 7 meters. Breakpoints may occur for more than 8 meters, and call quality exceeding 10 meters is greatly affected," the salesman said.
In addition, the salesperson reminds that since the Bluetooth headset may need to be worn on the ear for a long time, and the ear is soft, wearing it for a long time may make the ear uncomfortable. Therefore, it is necessary to personally wear a Bluetooth headset before purchase, and feel good comfort and then choose to purchase. .
