In this article, the editor will introduce the Bluetooth headset from both the appearance and experience of the Bluetooth headset.

1. Bluetooth headset shape classification

In-ear type (with handle): The main characteristic type uses silicone earplugs in the front section, which can greatly reduce the incoming external noise and have better bass effect. The disadvantage is that the in-ear type with poor design, especially the earphone handle is too heavy, which will cause The ear has a feeling of sagging, and it hurts after wearing it for a long time. There is no problem with a well-designed product. At present, the most popular is the in-ear earphone with handle. This type of mobile phone has excellent noise reduction ability, and at the same time has good sound quality and is easy to carry.

In-ear (bean): Compared with earphones with handles, the weight of this type of earphone will be more concentrated on the earphone head, the unit weight is relatively large, and it will have a greater sense of expansion after wearing it for a long time, and there is no silicone shark fin added. Headphones with stems are more likely to come off.

Semi-in-ear: The main difference between these types of earphones and in-ears is that they do not have silicone eartips, which are longer than the earliest flat earphones. Compared with in-ears, the air pressure in the ear canal is better relieved, but it is easier to compare. come off, and the noise control is poor.

In-ear collar type: The lanyard part of this type of earphone increases the battery capacity and generally has a longer battery life, but it is not free enough and inconvenient to clean up. At the same time, there is a certain stethoscope effect, which is not comfortable.

Headphones: Headphones are more comfortable from noise reduction to sound display, and they are comfortable. They cover almost all price points. The area of ​​the diaphragm and circuit specifications of the high-end version are also much higher, but the price is also much more expensive. , not very easy to clean up.

2. Basic factors that affect the experience of Bluetooth headsets

Comfort: The lighter the earphone, the more comfortable it is. The earphone with a relatively large size and weight will be much less wearable. The elasticity and workmanship of the earplugs on the head of the earphone will also greatly affect the wearing comfort. Generally speaking, the lighter weight Headphones, with good quality silicone earplugs, can improve comfort.

Stability: The earphones are not easy to be lost or dropped during wearing, which is especially important for frequent outdoor walking exercises. Usually, the all-in-ear type has the highest stability during use because it is stuck in the ear canal, while the in-ear type has a handle because it can be used. The main part is made smaller, the weight is relatively dispersed, and the stability is higher than the noise reduction beans without side buckles.

Battery life: At present, the battery life of most Bluetooth headsets can reach 3 hours (the headset itself), and with the battery compartment, it can reach about 20 hours. In actual use, most people cannot wear the headset all day. The only difference is that long-distance travel will require higher battery life. At present, there are mainly three companies in China, namely Xinwangda, Zijian Electronics and Shupeng Technology.

Charging method: At present, there is a battery compartment, and most of the charging is wired to support Apple and Android (type-c) interfaces. The charger can be used universally, and some front-row manufacturers have also begun to support wireless charging. The charging overcurrent protection IC (battery overcharge, overdischarge, overcurrent, overtemperature, short circuit) is mainly provided by Yutai, Siyuan Semiconductor, Weiyuan Semiconductor, Shengshengwei, and Weir.

Charging compartment design: At present, most of the charging compartments are designed with magnetic clamshells. Some charging compartments with poor design are not only difficult to handle, but also very easy to scratch their appearance. As an opening and closing operation with a very high frequency, this actually affects the experience very much.

Functional operation: At present, most Bluetooth headsets support touch. Although there is no physical button feedback, it will not produce a squeezing feeling. But if the touch sensor is not very good, the response speed will be very slow. There are both voice and voice prompts at present, and domestic manufacturers prefer to use language prompts.

Anti-interference: In our current use environment, there are a large number of devices in the frequency band where Bluetooth is located. The interference between the devices will cause the devices to be dropped or connected, but this is related to the design capabilities of many main control manufacturers. The performance section below There are detailed instructions.

Waterproof ability: In the past, many IP58 and the like, representing the dustproof and waterproof level, the headset usually only refers to waterproofing (the second value). At present, most of the earphones are IPX4 or above. For those who sweat a lot, or are prone to sweat or rain during exercise, the recommended level is 5. If you need to use it for swimming, it generally needs to reach IPX8 waterproof.

The above is the basic introduction to the Bluetooth headset.
