They are ok but a fundamental flaw
I bought these for motorcycling to cut down road and wind noise but still let me hear horns, sirens, etc.  They work well for that as they do not cut out as much as the foam plugs.  However. The part that sticks out of the ear is too short to get ahold of.  I put them in and needed help removing them.  I put some short wires on them so I cn get them out.  Seems to be a fundamental design flaw to me.  Plus I think they should go with a less expensive case (currently aluminum with threaded cap) and reduce the price.
