When purchasing headphones, the following aspects should be considered:
product quality
When buying Bluetooth headsets, we should pay more attention to the quality and performance of the products, such as battery life and radiation. However, due to cost control, the general inferior or inferior Bluetooth headsets can not be guaranteed in terms of workmanship or materials, and the product quality is poor, and the actual use function data is quite different, resulting in a large amount of radiation.
quality of connection
Because the call quality is a basic parameter to measure the quality of a Bluetooth headset, generally speaking, the call quality of a Bluetooth headset with a lever design is better than other types of products because its microphone is closer to the mouth.
idle time
Because this is the same as the daily use of mobile phones, the longer the standby time of headphones, the trouble of frequent charging can be avoided, which is also one of the standards to measure the performance of Bluetooth headphones.
Comfortable to wear
Human ears are delicate. If the ear hook material of the earphone is not good, or the design has some defects, it will feel uncomfortable after wearing it for a long time. So check carefully before buying and choose a Bluetooth headset that suits your ear type.
use
What is the main purpose of buying Bluetooth headsets? That depends on what you mainly do with it-language learning. Just choose headphones with a lower price. Earmuffs with adjustable volume are better. ② They are used for listening to news. Ordinary electromagnetic headphones will do. ③ Used for listening to music. Generally, to enjoy music, you only need to buy a mid-range machine, such as a stethoscope or headphones. If you want to enjoy high-quality music, regardless of the price, you should buy high-fidelity headphones, such as high-quality dynamic, flat film or capacitor headphones. Among them, the cost-effective BRD headset is the first choice. ④ Easy to use. Wireless Bluetooth headset is very convenient to use without wires. In addition, there are headphones with radio function, which allow you to listen to various languages and music programs at any time. ⑤ Audio track. Single-channel and dual-channel power amplifier equipment should be equipped with single-channel and dual-channel headphones respectively.
get along well with
When choosing a Bluetooth headset, the most important question is whether the mobile phone is compatible with the headset. Some Bluetooth headsets are not compatible with mobile phones, mainly because of different specifications. There are three main specifications of Bluetooth headset-——HandfreeProfile(HFP), HeadsetPro-file(HSP) and A2DP. HFP stands for hands-free function and HSP stands for earphone function. Consumers must first find out which specifications their mobile phones support, and then choose the right Bluetooth headset to use. A2DP refers to the advanced audio transmission specification, which allows the transmission of stereo audio signals with much better quality than HFP and HSP.
Bluetooth headset in HFP format supports relatively complete mobile phone functions, and consumers can operate hands-free options such as redial, call reservation and call rejection on the headset. Almost all Bluetooth headsets introduced by Nokia, Motorola and Sony Ericsson mainly support HFP format. Some models also support both HFP and HSP. For example, Pemet Bluetooth headset is A2DP format, which is compatible with HFP and HSP formats and is the best format version at present.
