So, I have a pair of these: https://www.midwayusa.com/product/1022464270?pid=224443

They worked OK for about the first 1.5 years I had them, but were buggy. I couldn't set the power down/sleep time. So it stayed at the default. Sort of annoying to have them power down at two hours, after you were sure you set them to 4 or never. At about the 1.5 year mark, the Bluetooth portion just stopped working. My phone can no longer see them and hence can't connect. I contacted Walker's and there is no reset process and they are out of warranty.... I'm SOL. The electronic hearing protection part still works, but you can get ones that do that for 1/2 the price.

So for Bluetooth and hearing protection, I use a $20 pair from Bestbuy when I'm mowing the grass and such. No electronic noise amplification, but that's fine. I don't need to hear the lawn mower.

I'm done messing with Walker's since this is the second Walker's product I've had die (first was a set of Bluetooth muff's that) and their Bluetooth radios suck (crappy connection with the phone in my pocket).

I'll probably try these next: https://proears.com/stealth-elite/
