Various earbuds (Woodley RG5)

Before these are consigned to the tip, we thought they might be useful to someone for parts or just yo use. They have possibly been used once or twice but several years ago and some have never been used, but we dont know which! There are 3 types:- conventional 2 bud, some single-ear buds, and 4 double earbuds with different shaped connector pins (see pic).
