Adaptive Sound Technologies LectroFan Classic — Black
Non-looping synthesised noise with more volume and depth than any fan machine.
The LectroFan Classic is the sound machine to buy when the noise you are fighting is loud. It synthesises its ten fan sounds and ten noise colours rather than playing recordings, so there is no loop to notice, and it produces more volume than any fan-based machine we list — enough to sit on top of traffic or a snorer. It is small, cheap to run from USB and has nothing to configure. What it lacks is a battery, any nature sounds, and the physical texture of moving air that makes some people prefer the Dohm. For a quiet-ish bedroom the Dohm or SNOOZ Pro is gentler; for a loud one, this.
Not ideal for: People who want moving-air texture, nature sounds or battery power.
