Market of blue tooth Head sets and Evils
The BlueAnt Q1 ($30) is a dual mic headset that offers 4 hours of talk time and 120 hours of standby. Its standout feature is its voice-control interface, which can accept voice commands such as “Answer,” “Call Speed Dial 1,” and “Check Battery.” It also has an excellent voice tutorial system that removes the need for reading an instruction manual. The voice tutorial can walk you through basic actions like how to pair the headset for the first time. Commands like “Teach me” or “What can I say?” will result in having the available options spoken to you.
The headset’s sleek and thin design is also a standout feature, looking unobtrusive in the ear. The headset’s only downsides are that its microphone faces only one direction and cannot be repositioned, and its noise cancellation technology is good but not up to par with the Jawbone or Plantronics. The Blueant Q1 comes with an earloop, two different sized earbuds, a USB charging adapter, and a wall adapter.

Aliph Jawbone II Bluetooth Headset with NoiseAssassin
Those looking for a bargain should consider the Aliph Jawbone II ($60), the predecessor of the latest Jawbone Prime headset. The Jawbone II is a Bluetooth 2.0 headset that offers superb audio performance in a small, sleek package. The headset weighs only 10 grams and is 2 inches long and 0.5 inches wide. The body of the Aliph has a modern sleek look and is slightly curved with a subtle diamond pattern on its surface. To keep it in place, the headset uses an earloop that wraps around the ear in order to keep it snug. The Aliph comes with 4 loops and 3 different sized earbuds.
Where the Jawbone II really makes it mark is its noise cancellation techology. The headset can be used in noisy rooms with very little of the exterior sound making it through to the caller. The main drawback to the Aliph Jawbone is battery life, offering only 4 hours of talk time (but an excellent 192 hours of standby). The Aliph’s small size restricts the size of the battery inside, and the result is less talk time than that of larger headsets.

Plantronics Discovery 975 Dual-Mic Noise Canceling Bluetooth Earipiece
The Plantronics Discovery 975 ($65) comes with 2 killer features: a thin, stick-like microphone stem and a leather carrying case with its own batteries that fully recharges the headset up to 2 times. With its thin shape, the Discovery 975 has the smallest and thinnest form factor of any Bluetooth headset we’ve seen yet. It comes with 2 buttons: a power/call button and a volume button that lets you cycle through 3 volume settings. The headset itself offers 5 hours of talk time and 168 hours of standby, but the leather carrying case gives an extra 10 hours of talk time. The 975 does not come with earloops, but instead uses an unusually shaped clear silicone eartip to keep it in the ear canal. It also supports Bluetooth 2.1. Because of the leather carrying case, the main downside of the Discovery 975 is its price. It comes with 3 eartips of different sizes and a wall charger.

The Application Of Wireless Bluetooth Headset
Currently Bluetooth technology in daily life is used the most widely in cell phone calls equipment that support of Bluetooth, such as mobile phones Bluetooth headsets, car hands-free Bluetooth, Bluetooth makes driving safer, many owners feel it’s inconvenient to answer the phone while driving: a hand hold on the steering wheel, the other hand hold the phone to answer, not only impede the shift, affecting the safety, two eyes staring at the front cars while have to look around to see if there are policemen; Car hands-free system access more convenience to answer the phone, but inevitably there are inconvenient phone call came at an inconvenient time; use a wired headset is also inconvenient , the sloshing of headphone line affects the activities of arm, shielding effect of headphone cable is poor, often effected by the electromagnetic noise, the phone throw on copilot seat also is often caught by the headphone cable in the clothes and fell to the ground when go off car …. … not only make people furious, but also tear for the accidentally injured car.
Mobile phones that use with Bluetooth headset can clear away the trouble, make driving safer. Through the mobile phone ear enable with Bluetooth ,users can achieve wireless hands-free functions, rather than now as you are hanging a line from the head to your phone. Users can also communicate via Bluetooth devices to use the phone, calls can be achieved without pulling out cell phone from the bag.
Ethernet electronics in order to promote its Bluetooth and even introduced a compact solar charger for hands-free with Bluetooth – Black King. King Kong uses rechargeable lithium battery, and configure a special solar charger. Drivers can receive calls without wearing a headset and the latest noise reduction technology can reduce the interference of other sounds, showing strong technological sophistication.
How good is Bluetooth headset? Wear a Bluetooth headset, you can be writing EMAIL while talking on the phone, you can be talking on the phone while driving, and you can be talking on the phone while doing housework, no annoying wires to tie your down! As a recent mobile advertisement support of Bluetooth headset: empty out hands, and let hands to do the right thing.
Using a Bluetooth headset, there is a benefit that we must not overlook: health! Friends often say phones must have this experience: with phone hand-held to speak near by his ear, not only prone to sore hands and neck, speaking for a long time will make his head gradually in pain. The electromagnetic waves of Bluetooth headset are lower than the phone’s electromagnetic, as long as put the phone inside the briefcase or pocket, you can put on the headset easy to say, neither hand up too high, but also effectively reduce the electromagnetic waves on the human body.
he specification of Bluetooth : two schools struggle .As for choose and buy Bluetooth headset, because there are many brands of the phone and headset, What disturb consumers most is the compatibility issues about cell phone and Bluetooth headset. Manufacturers pointed out that the Bluetooth headset in the specification, there are two factions of HandfreeProfile (HFP) and HeadsetProfile (HSP), decided headset and mobile phone compatibility. The former refers to hands-free function, the latter represents the headset features, consumers must first study their own mobile phones support which specification, and then find the right Bluetooth headset to use.
HFP format, which supports more complete of Bluetooth headset phone features, consumers can simultaneously operate functions of setting a good headset redial, call hold, call reject and other hands-free option on the phone. With Nokia, Motorola, Sony Ericsson and other manufacturers introduced several Bluetooth headsets as examples, almost all to support the HFP-based format, some models as well as support HFP and HSP, consumers should pay special attention to procurement.
In addition, consumers purchase Bluetooth products, they will often see Bluetooth1.1, 1.2,2.0 + EDR, 2.1 + EDR and other figures, numbers represent different specifications. Currently the most popular is 1.1, 1.2 is the new mainstream, 2.0 is launched in 2006, the latest version is version 2.1 + EDR, Bluetooth versions of Ultra-Wideband UWB will be available in 2008, Bluetooth version is different about the quality of the received signal, the new version more emphasis to overcome noise interference, and all the latest versions of Bluetooth are designed for backward compatibility with all previous versions, 2.0 and 1.1 versions of the device can freely connect, when purchase ,price and demand should be measured.
The Radiation Of Bluetooth Headset
According to the World Health Organization, IEEE and other experts panel , in testing Bluetooth products not found radiation that influent on the human body. Bluetooth is only 1 mW of output power , the power is one per million of the microwave oven, one-thousandth of the power of mobile phones, and these outputs, only a small part absorbed by the body. (Note: know the concept of 1 mW ? An ordinary 60-watt light bulb power, TV is as much as 300 watts of power, you now view this information ,the computer you have to use is 300 watts, the most “green” PHS transmit power has reached 400 mW per square meter, then the energy level should be quite safe, even if the Bluetooth manufacturers will power to maximum, but it is within 100 mW, the power of Bluetooth headset is only a quarter of the power of PHS, the radiation will not be great!
The effective transmission distance of the Bluetooth headset we often use is 10 meters, is fully adequate for everyday use, the Bluetooth headset itself, power is not large, only 1mW, a small Bluetooth headset is only about 20g, but the built-in battery can provide it with up to 200-300 hours of standby time, which fully proved its power, radiation can be basically negligible.
In actual use, you will not be uncomfortable for wearing a Bluetooth headset for a long time or using a Bluetooth headset to receive calls for a long time, but to use Bluetooth headsets are a way to avoid radiation, environmentally friendly way to call.
If careful observation, you can also find that using a Bluetooth headset near televisions, monitors, and do not cause interference to the equipment as mobile, it also proved the radiation of a Bluetooth headset is smaller than the cell phone, the anti-interference ability is much stronger.
Currently, mainstream mobile phones are Bluetooth-enabled, in some European countries, mobile phone + Bluetooth headset is very popular, many mobile phone users use a Bluetooth headset instead of handset to make calls, to avoid the impact of mobile phones on the head, reducing the radiation.

Mobile phones cause ‘five-fold increase in brain cancer risk’
People who started using mobile as teenagers and have been doing so for more than a decade are at a five-fold risk of developing a common type of brain cancer, new evidence indicates.
By Stephen Adams, Medical Correspondent,.telegraph.co.uk
Campaigners said the research, published in the International Journal of Oncology, was further evidence of the need to educate children of the potential dangers of talking on mobile phones.
Researchers from the University Hospital of Örebro and Umeå University examined the mobile and cordless phone use of more than 1,200 Swedes, who were diagnosed with malignant brain cancer between 1997 and 2003.
Of those, the 905 who were still alive were interviewed about their phone usage. For the remaining 346 who had died., researchers asked their relatives about their loved-ones’ telephone habits.
They then compared this to phone use information on almost 2,500 ‘controls’ who were either living and had no brain cancer, or had died of other causes. Each ‘case’ and each ‘control’ was matched for age, sex and social class.
*************************************************************
The 2G mobile network uses a frequency of 1.8 GHz the 3G 2.1GHz
and the cordless landline 1.88 GHz, WiFI 2.45 GHz and microwave ovens 2.45GHz (but only when they are on)
So cordless landlines operate at a very similar microwave frequency to mobiles. Also the data is carried as a modulation which is like a low frequency ‘pulse’. This is what makes the radiation so biologically active as shown in numerous lab experiments.
You can easily rent or buy monitoring equipment and you can see for yourself that the radiation emitted from a cordless landline when on a call is the same order of magnitude as from a mobile phone. Similar amounts of radiation being pumped into your brain and face. Brain tumours/mouth/eye cancers caused by cordless phones and mobile phones are on the same side of the head as you hold the phone.
There is now an infinite number of `peer reviewed’ International `scientific’ research available on the web’
And while checking out these `facts’ maybe you can also check out how many millions the mobile phone industry put into cancer research. It is very interesting that, as soon as we get the `scientific’ evidence’ that pulsed microwaves could cause cancer, we immediately have a denial published by the cancer `industry’. Follow the money!
Our
brain is the most complex and unknown part of the human body, yet the the
neuroscience has developed a lot in the past decades, and has been able to help the human being to have a knowledge of what’s inside. The discovery of the neuroplasticity, the
ability of the brain to create and develop neurons and connections to decrease
the natural cognitive decline and improve the brain capacity, has also been
breakthrough. It created a new form of training – the brain training programs.
When scientifically validated, these programs may change your life for the better.
