The LectroFan EVO is the follow-up to the classic LectroFan but features a new design and two new ocean surf sounds in addition to the 20 fan sounds and white noise variations. There’s also a new audio jack for connecting a portable speaker, pillow speaker, or even headphones for private relaxation. For Sleep, Rest and Relaxation The steady relaxing sound of a fan, surf, or white, pink, or brown noise can help you get to sleep more quickly and stay asleep longer by helping you tune out the environmental noises that might otherwise wake you at night. For Work, Study, and Privacy Using LectroFan EVO in your office or study area can help you focus, so you can get to work and get things done. It’s also a simple solution for improving privacy and helping make sure that your conversations don’t distract others So Much More Than a “Fan in a Box” Sleep technology has advanced beyond the outdated approach of using a mechanical fan with just a few speeds for audio variety. LectroFan EVO is the better solution. It’s electronic, with no motor or other internal moving parts. You get a much better variety of sounds, reproduced digitally via a large, high-fidelity speaker.
