[Elecraft] Best earbuds for KX1?

[J]

I've been using Sony earbuds that are more like small speakers that lie in
the ear.  

Fidelity seems OK;  highs and hiss are not emphasized.

The problem with these earbuds is they let in too much background noise.

 

I'd like some recommendations on earbuds with good CW performance,
sensitivity, low-hiss, that comfortably fit the ear canal to block out
noise.

 

Thanks & 73
