Flawed design - Walkers Alpha Power Muffs Electronic Hearing Protection & Enhancement

I've had 2 pair of the Walker Alpha Power Muffs break. The muff part breaks off of the head band far too easily. I have a hearing disorder (hyperacusis) so I wear some sort of hearing protection most of the time. The Walker Alpha work great as far as the ability to muff and to enhance but structurally are flawed. The first pair fell off of a chair onto thick carpet and broke the second pair broke off in my hand as I was putting them on.
Not happy, would not recommend.
