Earlove plugs come in Stadard and Large size. Recent studies of both fit and seal, conducted at Etymotic Research and an independent lab, showed that the smaller of the two sizes fits the majority of ears more comfortably for longer periods of time and is now designated as standard fit. The Standard fit was previously called 'lil earlove. Two sizes of Earlove fit almost 100% of ear canals.
All ears are different. It is impossible to predict the size of an ear canal by the appearance of the outer ear, or by a person’s physical size, age or gender.
