Very happy with these headphones. They are very easy to pair to my phone. The controls are very simple. I have used them twice for two to three hours each time. I like to listen to audio books while I mow grass. The sound amplification is great and they work very well for sound blocking. I will be purchasing more of these for keeping near the bed for those late night "what's that sound?" investigations.

I got these mostly for hearing protection while using equipment - tractor, weedeater, chainsaw, etc. - and wanted the highest NRR available in an earbud style. I wanted the earbuds rather than the headphones so that I can wear a hat, goggles, and other protective equipment. These Walker's are great - much better than the foam earplugs I have that are "rated" at 33 db NRR. And I love the fact that I can still hear what is going on without having to take the plugs out. I had the opportunity to shoot with someone who has a .303 British rifle. I was worried that these Walker's would not be enough, but they were great, even for that very loud rifle. I like having the Bluetooth capability - it works great, though I don't really use it that much.
I also like these because they have the around the neck base, which gives them better battery life (I have yet to run them down, even with several hours of use) and keeps me from losing one if I am swiped by tree limbs. The neck piece is quite comfortable and really does not get in the way.
My only concern is that they are not rated any level of water resistant. So far this is not an issue, but I worry that excess dust, heavy sweating, or getting caught in some rain may be a problem.

Do not buy they don’t work together

THESE WORK GREAT! I CAN'T HEAR ANYTHING RIGHT NOW! ESPECIALLY MY WIFE NAGGING AT ME. THANKS!!!

Good for keeping eyes safe for hard work and tint makes you feel like you’re in Las Vegas circa Blade Runner 2049.
