Home What's New How2.0 Science Computers & Elec. Aviation & Space Automotive Tech Technology Medicine It's a brave new wireless world, yet most portable-audio hounds are still tangled up in headphone cords. Soon, though, you'll have lots of wireless stereo headphones to choose from. The technology isn't brand new, but until recently it was too bulky and expensive to shove into the tiny, splurge-worthy gadgets we love. Expect to see three flavors of wireless earmuffsBluetooth, Wi-Fi and magnetic induction [see sidebar below]rolling out between now and early next year. These airy headphones will connect wirelessly to audio players, mobile phones, laptops, stereo systems and game consoles for unencumbered musical bliss. Logitech Wireless Headphones for MP3 ($130; logitech.com) Range: 33 feet Battery life: 8 hours Logitech's Bluetooth transmitter plugs into a standard 3.5mm jack to make the headphones compatible with almost any audio device. Computers with Bluetooth Advanced Audio Distribution Profile (A2DP) will also send music to the headphones. Plantronics Pulsar 590 ($200 with adapter;

Home What's New How2.0 Science Computers & Elec. Aviation & Space Automotive Tech Technology Medicine WHAT'S NEXT Your Personal Sound Bubble Unlike Bluetooth and Wi-Fi, magnetic induction does not transmit data via radio frequencies, which propagate indiscriminately beyond the headphones range. Instead it encodes the audio in a weak magnetic field. Because each magnetic bubble extends only six feet around the transmitter, there is essentially zero interference from other devices using the same signal protocol. Technology developer Aura Communications (auracomm.com) boasts of power-consumption, cost and security advantages as well. Consumer-electronics companies, including Creative Labs, have shown prototype magnetic-induction players. Some could hit shelves by years end. 1 |2 Jeff Harris

Troubleshooting

The adapter or headphones will not turn on. 1. Make sure the adapter and headphones are fully charged. 2. Press and hold the Connect button until the LED begins to flash (should take 3 seconds). 3. If the adapter or headphones still will not turn on, press the Reset button (requires a paper clip). 4. Headphones will NOT turn on while charging. The adapter and headphones turn on, but will not connect to each other. 1. Make sure both devices are off. 2. Turn on the headphones first, then the adapter. The devices should automatically connect to each other. 3. If the devices still do not connect, wait until the adapter and headphone LEDs are solid red, and then momentarily press the Connect button on the headphones. 4. If they still do not connect, try re-pairing the devices. How do I re-pair the adapter and headphones? 1. Turn both devices off. 2. Press and hold the Connect button on each device until the LED flashes red and blue (should take 10 seconds). 3. When the LEDs are solid blue (after 15-30 seconds), re-pairing is complete. The adapter and headphones are connected, but no music is coming through the headphones. 1. Make sure your iPod or MP3 player is powered on and playing. 2. Make sure the volume level on your headphones is at least halfway up. 3. Make sure the volume level on your iPod or MP3 player is at least halfway up. The music signal breaks up. 1. When indoors, you will get the best reception if you use the headphones in the same room as your iPod or MP3 player. 2. When outdoors, you will get the best reception if you carry your iPod or MP3 player on the right side of your body.
