Logitech EasyFit Mobile headsets

Realizing that earpieces are not a universal fit for all,
Logitech has developed the EasyFit Mobile line, which includes five different headsets and nine different connectors
(for basically any cellphone currently available). They've split up the package so you can pick and choose from three over-ear pieces, earbuds, or earbud booms (with small, medium, and large ear fittings), and then choose a connector to fit your phone.
