The HiFast Wireless FM Audio Transmitter is a USB dongle that plugs into your computer and beams the audio signal to the nearest FM radio receiver. These things have been around a while, but this model apparently has some nice quartz PLL lock-on tech built-in which means you get clearer sound with less buzz, crackle and pop. It’s USB powered, transmits up to 160 feet and costs $69.99.
This device modulates computer audio into stereo FM signal and transmits wirelessly to your FM radio, wireless-earphones or home theater systems. Enjoy your favorite music with Hi-Fi quality and convenience without making any changes to your computer and audio systems. With the advanced feature of 7 Channels/selectable transmission frequencies, now you can easily avoid conflicting with local FM radio signals.
