I was skeptical about these as I have read mixed reviews, but after using them for over a year I can say that these are the best shooting Bluetooth/noise canceling/touch control earbuds I have found. They pair automatically, cancel pulse/gunfire sounds while letting background sound through, take and make calls well, and they sound fine playing podcasts or music. They aren’t gonna deliver booming bass, but they’re completely great for functionality, and they do everything they say they’ll do. I am an avid shooter and I also work behind a 372xp chainsaw every day, and have tried 3 different sets of various brands of Bluetooth noise cancelling earphones -and have been disappointed with them all, until I found these. The others all stay in the drawer now because these Caldwells are GREAT. The slide volume control must be swept up or down a few times as each sweep does a small adjustment, but once you get the hang of it, it works fine to adjust volume. All the other touch controls are fairly intuitive and straight forward. These work one at a time as a single earpiece or simultaneously as Bluetooth headphones and have fully ambidextrous/identical controls on each bud. Although there is a right and left earbud, either bud can be used in either ear. They stay securely in the ears once you find your proper tip that fits (I use the large foam tips for the best fit/seal/noise protection), and the FDE color matches a couple of my guns and gear???????????????????????? *The foam tips MUST be used for sufficient ear protection while shooting. Outdoors anything non-magnum is fine with these. Indoor range visits and I’d double up with earmuffs worn over these for full sound protection Overall, I am EXTREMELY happy with these. One or both of them are in my ears almost all day long. They have a few specific quirks that I had to figure out (see re-syncing process outlined below), but these are hands down the best Bluetooth noise cancelling earbuds around for the price. On the newer model of these (the emax PRO version) I think that Caldwell shouldn’t have made the right and left earbuds have different controls on the new “PRO”. These original Shadows are far more utilitarian with the exact same touch controls on either earbud. Just something to consider if you’re deciding between these or the Pros, I’d pick these original Emax shadows all day long over the new PROS for that reason Many have complained about the earbuds losing sync with each other, and then the user has a very difficult time getting them to sync with each other again as a set. I can say that the number one cause of them not syncing with each other is because whatever Bluetooth device they were paired to MUST be turned off. When these earbuds lose sync with each other, their device (usually a phone) will then recognize each earbud as a separate unit, and only one earbud will give sound at a time. The fix for this is: 1. TURN OFF YOUR PHONE so no Bluetooth pairing is possible with that device. These earbuds WILL NOT sync again if one or both of them is paired with a phone or similar device, or if said device (or any other device within range) “remembers” either of them and is trying to pair with them. Turn off the device. 2. Perform the factory reset. It is a 20 second process that has a YouTube video under “Caldwell Emax shadows factory reset” 3. Once factory reset is complete (making sure your phone remains off), place earbuds back in their charging case and make sure the light on the back of each is either solid green (fully charged), or solid red (partially charged/need charging). 4. Remove both earbuds from case at the same time and place them in your ears. They should turn on and pair to each other automatically in a few seconds. Usually if you put them right in your ears you will hear the “paired” BOOP sound in both earbuds. You can perform a 2 second touch/hold on one earbud to activate passthrough mode and listen if both earbuds then allow you to hear outside sounds (make sure your phone remains off for these steps!). If long hold on one earbud doesn’t activate passthrough mode on both earbuds, they aren’t synced and the first steps outlined here should be performed again. 5. Once you’ve determined that they are synced by doing the passthrough mode test, you can turn your phone back on, enable Bluetooth, and click on “SHADOWS” under your Bluetooth menu. Click on it and you are back in business with a “paired” status on your phone and a BOOP sound in both ears to confirm the connection Your phone must be turned off and factory reset performed for them to sync with each other once they become unsynced or else your phone will pair with each earbud as a separate Bluetooth device, preventing them from ever syncing with each other. That can be really frustrating, so follow the steps above. I hope this helps those who have been frustrated by them not syncing. These are great Bluetooth shooting earbuds, especially for the price. I own 3 sets so I always have a charged one or pair in my ears.
