1.Option: Bluetooth IC is its foundation, just like the CPU of a computer. It is the heart. A good solution can produce a good product.
2.Look at the signal: since Bluetooth headset is a wireless product, the stronger the signal, the better. The normal range is within 10 meters. If the mobile phone has no signal in its pocket, it won't work much.
3.Look at the appearance process: if a product has rough appearance and many defects, I think there will be no guarantee in terms of quality, and the face project should also be done well.
4.Listen to the sound quality effect. You can judge the sound quality effect by listening to music at home. The sound quality must be better than ordinary headphone cable, and there should be no noise and current sound.
5.It also depends on the call effect. Remember to try the effect of wheat. After connecting the mobile phone, call your dear friends to see how the call quality is and whether the sound size is in the normal range. Whether there is echo or noise, current sound, etc. If any, give feedback to the merchant in time.
6.Look at the standby time. The battery of a good Bluetooth headset is also very durable. Generally speaking, you can talk or listen to music for four or five hours, and you can stand by for 3-5 days. But these are just for reference. Each Bluetooth headset will be different.
7.Choosing a brand, a good brand of Bluetooth headset must have its advantages. Now the Bluetooth industry is also difficult to do. If the products are not outstanding, it is difficult to sell at a high price. Moreover, only a few brand Bluetooth headsets can be shortlisted every year. Therefore, it can be said without hesitation that the quality of a good brand of Bluetooth headset is really good. Just feel if your purse is big enough when you buy it. Just buy your own Bluetooth headset. There's no need to blindly pursue big brands. It's too expensive.
8.Look at the accessories. Poor headphones have poor charger and charging cable quality. You can feel it by comparing them with your hand. The quality of the charger must be better, because it is related to the power safety here. You can't buy a Bluetooth headset with potential safety hazards.
