The original LectroFan (now referred to as LectroFan Classic) and LectroFan EVO are very similar. Here’s how the EVO is different:

Design: the EVO has the same seven-sided shape as the original model, but with softer edges. The speaker grille is angled, and the control panel has been moved to the top for improved ergonomics.

Sounds: the EVO has the same high quality fan sounds and white, pink, noise and brown noise variations. We’ve added two ocean sounds, for a total of 22 choices.

Features: the EVO also offers an audio output jack. You can connect a portable speaker, a pillow speaker, headphones, or any other device which uses a 3.5mm audio input.
