Radio Headsets
Headsets, also known as headphones, are hearing devices that are actually miniature speaker systems. They are stereo hearing systems that can be worn near the ear, thus providing mobility to the user. Traditional headsets were bulky and large with two speakers for both the ears encased in padded ovular ear cups. These ear cups were attached to a headband in the shape of an arch that went over the head. Each of these ear cups had a signal wire joined down together as a single wire, which was connected to the audio player or radio through a headphone jack.
Today's headsets, especially radio headsets, are technological wonders-extremely lightweight with no irritating cords, almost negligible in appearance, sound quality, durability and comfort. They are equipped with superior technologies like push-to-talk and duplex wireless transceivers. These can transmit scrambled digital signals in a spread spectrum format for ensuring complete security and privacy to the user. Radio headsets also have the noise cancellation option for better acoustics.
Radio wireless headsets have wider ranges of up to 300 feet or 90 meters.
They use frequencies of 2.4GHz and can be receive transmission even through walls. Sound quality, speaker power, bass and treble range are some features to look for in a radio headset. Other options are the accessibility of the controls like volume and frequency. The battery is also important as the total cost of ownership depends on the batteries. Some radio headphones use rechargeable batteries.
The style and comfort are other factors to be considered while buying a radio headset.
There are several manufacturers of radio headsets like David Clark, BHI, Kenwood, Warren Gregoire and others. The Internet is the best source to find out more about buying a radio headset. There are many websites that provide information about the products, along with other offers, discounts and warranties. A good radio headset is around $30, though it varies according to model..

A Bright Future Predicted for Skateboarders with SunRiser Skateboard Headlights and Tail-Lights
Bend, OR (ContentDesk) January 25, 2006 -- Thousands of skateboarders can now be seen at night thanks to a surprisingly small invention. The SunRiser skateboard headlight and tail-light are no larger than the standard 1/4" thick riser pad currently being used on skateboards, but project a powerful light from 3 LED lamps, 2 replaceable cell batteries, and an on/off switch.Skateboarders have been finding out the hard way that most US cities require skateboards to meet the same lighting regulations as bicycles for night riding, a forward facing white light and rear facing red light.SunRisers easily install on any current skateboard. Simply unbolt the trucks (axle) from the deck (board), slide a headlight or tail-light in place, and rebolt. The polycarbonate case can withstand enormous impact and is unobtrusive to skateboarding tricks.SunRisers are available through the company website and local skateboard shops for $24.95 each, or a $49.95 set which includes a headlight, tail-light, and...

New COMBO-Project Aims to Reduce Exhaust of Carbon-Dioxide and Global Warming
Sint-Niklaas, Belgium (ContentDesk) August 3, 2006 -- The system requires all countries, governments, politicians, etc. to be on the same level regarding their perspective on the future. The separate plans and ideas to fight pollution, does not go hand in hand with new nuclear plants. It is completely controversial with the projects to make people aware of renewable energy, or reducing their energy consumption.Several countries already have an electronic system, such as Germany, Austria, Denmark, etc. Others, are using a system to rise TOLL, by entering a city, such as London.
The COMBO-project is an advanced version of all of these systems, making it possible to extend at any time, depending on the needs and
requests.But compatibility remains necessary at all costs. Many trucks and buses are already provided with a transponder system. It is of crucial importance, that no more than one transponder in each vehicle is needed, to drive in or through other countries.This...
