EP-51 Skip Track Remote Not Working

Is anyone else facing this problem?

Skip track back and forward not working -

Press twice to go forward - not working
Press three times to go back - not working
Press once to play and stop - working fine

Using an iPhone 6s with iOS 9.3.5

A journalist responded to my request for specific help.

For your future reference:

To skip forward a track: press and HOLD the ‘-’ volume button

To skip back a track: press and HOLD the ‘+’ volume button.

It is not double and triple click like on other headsets.

Yeah thats whats written in the instruction sheed sigh

Its inside the little carrying bag for reference.
