Verizon iPhone 4 Bluetooth Headsets

http://lib.store.yahoo.net/lib/yhst-129611484221105/verizon-iphone-bluetooth.jpegFor most users of the new Verizon iPhone 4, a Bluetooth headset is a must-have accessory. But choosing a Bluetooth headset can be a big challenge because of all the various features that are available. In this article, we try to streamline that process by examining the most popular of those new features. The Verizon iPhone 4 has burst onto the smartphone scene and become an instant success. One of the most exciting aspects of this new cell phone is the great variety of Verizon iPhone 4 accessories that are available. If you want a Verizon iPhone 4 case or a Verizon iPhone 4 screen protector, you’re not going to have much difficulty finding the perfect one. The same goes for Bluetooth headsets, which many iPhone 4 users consider a must-have accessory. The problem with choosing a Bluetooth headset is that the technology is advancing so rapidly. There are so many options and various features on the market right now that it can be quite overwhelming to the uninitiated. So in order to help, we’ll examine some of the most popular features and try to give you an indication of how useful they are. Some of the most popular and most confusing features included with modern Bluetooth headsets are those that deal with sound, such as noise reduction, noise cancellation and noise isolation. Noise isolation is a passive feature that creates a seal with the ear canal and prevents it from discerning external sounds. Active techniques don’t simply block the sound; they accept it, filter it and then pass it along to the ear. The difference between noise reduction and noise cancellation is in how they filter the unwanted sound. Reduction involves using resistance to diminish while the cancellation methods create opposing sound that has a zeroing out effect. Cancellation is more effective and more expensive than reduction, and reduction is more effective and more expensive than isolation. Recently, the manufacturers of premium Bluetooth headsets have begun to integrate voice control and text-to-speech features directly into the headsets. They do this by including a microchip that does its own processing independent of the smartphone. Voice control allows the user to answer calls and to dial phone numbers by speaking. The headset detects the speech, and then translates it into a digital command that the smartphone understands and can execute. With the text-to-speech feature, the Bluetooth headset can pronounce the information from caller ID, so that you can choose to pick up or ignore the call without actually looking at the screen. Some Bluetooth headsets also include an LCD screen, which usually detaches from the earpiece. The benefit of having a separate LCD screen is that you can examine the caller ID information and explore your contacts without having to access your phone. In many cases, your phone will be in a pocket, briefcase or purse while you’re on the go. Some of these LCD displays are quite sophisticated and can tap into phone features, such as providing access to tweets, breaking news and sport tickers. Most Bluetooth headsets provide enough noise isolation that they can emit a beep or play a ringtone for incoming calls without that tone being audible to others nearby. Some Bluetooth headphones have a vibration feature so that you can detect calls without sound. Bluetooth headsets with a binaural configuration have also become more popular recently. Binaural models have an earpiece in both ears. Thanks to new, sophisticated noise-cancellation features, these are not as dangerous as they once were. However, due to those features, a good headset can be quite expensive. Another big difference in modern Bluetooth headsets has been the reduction of the boom microphone. Now you can get units with only slight microphone stems.
