Hi sil.lenzi45,

there are 3 different sizes of earplugs, all of which fit different ear types.
With the ergonomic surface design, these small and lightweight headphones are comfortable to wear all day even for smaller ears.
The WF-C700N headphones fit comfortably and securely with their ear-moulded shape and ergonomic surface design. We have also evaluated the sensitivity of different ear types for an ideal shape that is comfortable for many people.
For more information on the design and specifications, visit our support page.

difficult to say as mine are rather small but there are 3 different sizes of plugs, one was too small for me so it may well be, i am very happy with the headphones
