I use these plugfone bluetooth ear buds to mow without damaging my hearing. The only problem is that they kind of hang there and slowly get pulled out over time. The body is light, but every 20-30 minutes you need to readjust.
The body slides nicely into this clip and the clip fits really snugly on my sweat band. Now when I turn my head the body moves with it. Now the ear buds alway stay snug in my ear keeping out the terrible mower noise.
