Bought these were because the smartphone has not identified other existing headsets or were not compatible.
The headset comes in an envelope in plain foil with 2 pairs of replacement rubber.
Unfortunately, when buying only just a headset supplied and the second forget when subsequent delivery lacked the second pair of rubber plug for the ears and the headset saw a total of not so repackaged like at the first show, but there's one star less.
There are no defects and run and run ...
