What makes Plumo different
Most sleep earbuds work by pushing a driver into your ear canal and hoping you can sleep through the pressure. Most bedside speakers work by throwing sound into the room and hoping the person next to you doesn't mind. Most people give up on both, and either lie awake in silence or keep waking their partner.
Plumo works differently. At 12 mm it sits flat inside the pillow, and PillowPath™ delivery sends the sound through the fabric to the ear resting on it. Sit up and it's already gone.
