Plastic Injection Tooling Quality Control

  Bluetooth headset is the application of Bluetooth technology for hands-free, so that users can avoid to take the wires and freely call in various ways. Since the advent of bluetooth headsets, it has been a good tool for mobile business to improve efficiency. Bluetooth is a short-range wireless communication technology with low cost and large capacity. In 1995, Ericsson Group first proposed the concept of Bluetooth. The Bluetooth specification works in the microwave frequency band, with a transmission rate of 1M bytes per second, a maximum transmission distance of 10 meters and 100 meters by increasing the transmit power. Bluetooth technology is open globally and has good compatibility worldwide. The whole world can be connected through a low-cost invisible Bluetooth network.


Bluetooth headsets are divided into three categories: mono, stereo and true wireless.


When buying headphones, the main considerations are as follows:


1) Product quality

Buying a Bluetooth headset should pay more attention to the quality and performance of the product, such as battery life and radiation level. In general, inferior quality Bluetooth headsets can not be guaranteed in terms of workmanship or materials due to cost control. The product quality is poor, the actual function data are quite difference and the radiation is very high.


2) Call quality

  Because call quality is a basic parameter to measure the quality of a Bluetooth headset. under normal circumstances, the use of a rod-type Bluetooth headset, because its microphone is closer to the mouth, the call quality obtained is better than other types of products.


3) Standby time

  This is the same as the daily use of mobile phones. The longer the headset's standby time, the trouble of frequent charging can be avoided, which is also one of the standards for measuring the performance of Bluetooth headsets.


4) Wearing comfort

  Human ears are relatively delicate. If the material of the earhook of the earphone is not good or there are some defects in the design, after wearing it for a long time, it will feel uncomfortable. Therefore, you should check carefully before buying it,  choosing a Bluetooth headset that fits your ear shape is important.


5) Purpose

  What is the main reason for buying a Bluetooth headset?

①For language learning. Just choose a lower-priced headphone, and the earmuff type with volume adjustment is better,

② Used to listen to news. Ordinary electromagnetic headphones are sufficient.

③ Used to listen to music. To enjoy music in general, you only need to buy a mid-range machine, such as auscultatory or headphone. If you want to enjoy high-quality music, you should choose high-fidelity headphones, such as high-quality moving coil, flat-film or condenser headphones, regardless of the price.

④ Easy to use. The wireless Bluetooth headset does not need to be connected, so it is extremely convenient to use. In addition, there are headphones with radio function, which can allow you to listen to various languages and music programs at any time.

⑤ Channel. Mono and dual channel amplifier equipment should be equipped with single and dual channel headphones, respectively.


6) Compatibility

  When buying a Bluetooth headset, the most important question is whether the phone is compatible with the headset. Some Bluetooth headsets are not compatible with mobile phones, mainly because of different specifications. There are three major specifications for Bluetooth headsets-HandfreeProfile (HFP) and HeadsetPro-file (HSP) and A2DP. HFP stands for hands-free function, and HSP stands for headset function. Consumers must first figure out which specifications their phones support, and then choose the right Bluetooth headset to pair with. A2DP refers to the advanced audio transmission specification, which allows the transmission of stereo audio signals, and the quality is much better than HFP and HSP.

  The HFP format Bluetooth headset supports relatively complete mobile phone functions. Consumers can operate the hands-free options such as redial, call hold, and call rejection on the headset. Almost all Bluetooth headsets introduced by Nokia, Motorola, Sony Ericsson and others support the HFP format. Some models also support HFP and HSP.


7) Chip brand

  There are three major chip suppliers for Bluetooth headsets, one is CSR in the United Kingdom and the other is Broadcom in the United States. Broadcom's products account for more than 80% of the market.


8) Transmission distance

  The transmission distance of the Bluetooth headset is also a problem that everyone is more concerned about. The transmission distance of the Bluetooth headset has nothing to do with the Bluetooth version, mainly depends on the advanced technology. The standard transmission distance of PowerClass2 is 10 meters; while the upgraded PowerClass1 will increase the transmission distance to 100 meters and provide Hi-Fi stereo effect. Generally speaking, the distance between the mobile phone and the Bluetooth headset is not too far, and the relatively safe transmission distance is about 2 meters to 3 meters.


9) Version

   When consumers purchase Bluetooth headsets, they often see Bluetooth1.1, 1.2, 2.0 + EDR, 2.1 + EDR and other numbers, and the numbers represent different specifications and standards. At present, 1.1 is the most common, 1.2 is the new mainstream, 2.0 is launched in 2006, 2.1 + EDR version, the latest is 3.0 is the mainstream, 4.0 is the latest Bluetooth headset technology, these numbers represent different versions, and also represent the headset Anti-jamming Bluetooth headset capability. Different Bluetooth versions are related to the quality of the received signal. The new version emphasizes the ability to overcome noise interference. The new version can be backward compatible, consumers should measure the price and demand when buying.


10) Shape

  In addition to functional considerations, the appearance and wearing comfort of Bluetooth headsets are also the keys that consumers must pay attention to when purchasing. Each person's face shape is different, users should try wearing comfort before buying, and then buy.
