How to Choose a Perfect Bluetooth Headset
Since the introducing of Bluetooth in wireless transmission, the speed of information transfer is double times than infrared technology age. As for cell phone users, many of them prefer to choose cell phones with Bluetooth function because it is more convenient and simple to make phone call and listen to the music with the Bluetooth headset. But, some people don't know how to choose a suitable Bluetooth earphone for their devices, or to use them correctly. Let's start to learn about it now.
What is Bluetooth?
Simply speaking, Bluetooth is a wireless transmission protocol. It supports short distant communications (usually within 10m) between devices like mobile phones, PDA, wireless headsets, laptops, related peripherals and other wireless information transmit equipments. The standard of Bluetooth is IEEE802.15. Its working frequency is 2.4GHz frequency, and its bandwidth is 1Mb / s.
The name of Bluetooth was originally from a king of Denmark in the 10th century, who untied Sweden, Finland and Denmark. Therefore, Bluetooth has the meaning of divided unified.
How does it work and what's the function?
Bluetooth technology combines with high-speed FH (Frequency Hopping), TDMA (Time Division Multi-Access) and other advanced technologies to link network in the cheapest way in a short distance between several digital devices. It is the bridge for network interface to connect various peripheral devices outside internet
Since it is wireless, electronic devices can be connected with each other via Bluetooth without cable. Through the wireless receiver on a chip, equipped with Bluetooth technology, electronic products can be interlinked with each other within ten meters' distance. And the transmission speed is up to 1 megabyte per second. The infrared transmission technology in the past can only connect electronic devices in the distance of sight view. But, the Bluetooth technology avoids this kind of trouble.
How to choose Bluetooth headset for your cell phone?
The most trouble thing for people to choose Bluetooth headset for their mobile phone is the problem of compatibility between them.
Manufactures pointed out that there two main factions for Bluetooth headset, the Hand free Profile (HFP) and Headset Profile (HSP). The former refers to hands-free function, while the latter represents the headset features. Consumers have to figure out the Bluetooth support standard of their own mobile phones before buying.
However, Bluetooth in HFP format supports more complete phone functions. Consumers can pre-set the phone via headset to operate a redial, call hold, call reject and other hands-free functions. Bluetooth headset launched by Nokia, Motorola, Sony Ericssion, for instance, all support HFP format. There are some models that support both HFP and HSP.
Generally speaking, when we purchase the Bluetooth headset, we should concern about the headset's performance in following areas:
Call quality. It is a basic requirement to measure the quality of a Bluetooth headset. Usually, the call quality of the Bluetooth headset designed with rob is better than others'. Since the microphone is closer to the mouth. This is why consumers prefer the older generation of Sony Ericsson HBH35.
Compatibility. Although most Bluetooth products don't exist serious problem in this area, it is still useless if the headset can not compatible with the mobile phone well. Like Nokia HDW-3, it is inconvenient for users to charge since there is no suitable charger for it.
Comfort in wearing. Ears are so delicate that it will cause discomfort if the headset material or design is not good. Therefore, consumers should check it carefully before buying, and choose the one suit your ears. In addition, it will be better to choose a wired headset or hands-free headset for consumers who wear glasses.
Standby time. Like mobile phones, the longer the standby time is, the better the device is. It avoids the trouble to recharge the headset frequently if its standby time is long enough. Headset, like Sony Ericsson and Motorola HS810, has longer working and standby time.
Weight. This factor is also important for the weight capacity of the ears. In Theory, the lighter the headset is, the better it is for users. But now the weight of most Bluetooth headset is about 20 grams. There's no big difference in weight.
All in all, choosing the Bluetooth headset is as important as buying a mobile phone. Hope those tips above can help you learn to choose perfect headset. In addition, I'd like to introduce you a great store for Bluetooth headset, http://www.dinodirect.com/stereo-headsets/
