ISOtunes has come on the market with hearing protection designed for the shooter under the ISOtunes Sport brand. ISOtunes has made industrial hearing protection for some time, but just recently introduced the Sport brand. There are currently two models to choose from, the Defy, and the Advance. They are both very similar in use. The Defy is your standard Over Ear (muff) style, while the Advance is an In-Ear style.

Both the Defy and Advance are packed with features. One of those is that they both have the “Tactical sound” control. The Tactical sound control is a separate volume control for outside sound. ISOtunes Sport claims an increase in exterior sound up to 8x their normal volume. If you turn it up, it amplifies everything, including background noise. This can be a plus when listening to range commands, your friends, or while hunting. You can also turn it all the way down, which essentially cuts all exterior volume. Don’t worry, the Tactical sound control still reduces loud noises to a safe level, so as to not damage your hearing. When you power on the ISOtunes Sport’s the Tactical sound turns on to about half volume. One of my only complaints is that I wish they would remember the last volume setting when turned off. The high impact noise response time is listed at less than 2 milliseconds, so hearing damage is greatly, if not completely, reduced by the initial gun shot sound.

Since we are talking about sound, both the Defy and Advance have bluetooth connectivity. As with most bluetooth, just pair it to your device and away you go. They do both have noise cancelling mic’s, so if you are on a phone call at the range, whoever you are talking with can hear you clearly. My daughter called me at the range one day while I had the Advance on. She said that she could hear me fine even with the occasional gun shots. So that part seems to work okay. With the bluetooth, you can also use the Advance or Defy to listen to your favorite podcast or music. However, the ISOtunes Sport line will cap the output volume to 85 db’s using their “SafeMax” technology. This is because 85 db’s is the safe volume limit for all day long exposure. If you are in an extremely loud environment, it can sometimes still be hard to hear whatever is playing through the bluetooth. The bluetooth controls are separate from the Tactical Sound controls, making it easier to know which volume you are adjusting.

Even though the Defy and Advance have similar features, there are some differences besides the obvious. The Advance in-ear is listed as a 26db NRR (noise reduction rating), but the Defy only comes in with a 25db NRR rating. Definitely not enough for me to tell the difference. Connection to a device, via bluetooth, varies by an hour with the lead going to the Defy at 11 hours and the Advance at 10 hours. When not connected to bluetooth, the times can jump up a couple of hours. The Defy has the option of using 3 AAA batteries instead of the supplied rechargeable. This increases the use time to 22 hours. It also gives the Defy an option if the rechargeable battery dies when using them in the field. The Advance, being an in-ear, does not have this luxury. Both have auto off functions also. The Advance’s is 2 hrs of non use, while the Defy is 4 hrs. Both are resistant to dust and water. Since the Defy and Advance are different styles, there is definitely going to be a weight difference. The Defy (over ear) comes in at 15.5 ounces, while the Advance (in-ear) comes in at 23.25 grams, or just under an ounce. The Defy and Advance come with a usb charging cord. While the Advance also comes with 4 sizes of eartips and one set of triple flange style to use when you’re not worried about sound suppression. The Advance also comes with a zippered carrying case.

After using the ISOtunes Sport’s for a while, I’ve concluded that both are really good at what they do. The Tactical Sound works great and lets me hear range commands and friends clearly. It also does a decent job of not amplifying wind. Not perfect, but better than some hearing protection I’ve used, at least as far as wind noise is concerned. I simply love the Advance, as they give me lightweight in-ear protection. The Advance allows me to use rifles and shotguns without causing any problems with a cheek weld. Plus they are not hot like over the ear ones can be. I also use the bluetooth, on the Advance, daily while at work. They are fantastic for this. If you work in a loud industrial environment, they are even better. The Advance is my newest favorite hearing protection. The Defy, however, is not far behind the Advance. It has its own advantages. They are very comfortable for over the ear hearing protection. They have the option of running AAA batteries. The top strap has a slot for heat management, or more importantly, so the button on your hat doesn’t push against your head. The cushions are also very soft and comfortable. The Defy will also open up extremely wide, so if you have an extremely large brain capsule, these might work well for you. I like the Defy if I’m just shooting pistols, or when it’s cooler outside.

If you’re looking into some new hearing protection, I wouldn’t hesitate to check out the ISOtunes Sport line. Both have great useful features. My favorite would be the Advance, but the Defy are really good also. Anytime you can get decent hearing protection, with decent rechargeable battery life, I’m all for it. Go check out the Defy and Advance at ISOtune Sport, you’ll probably like what you see.

Does the job

These rock! I am a firearms instructor for my local LE Agency. These guys seem a little awkward at first as fas as getting them to fit correctly. But once I found the earplugs that fit the best... they do exactly what they were intended to do.

I completely charged them as the directions stated and the next day I set out to the range and spent 5 hours wearing them. I had no issues with short battery life as some would expect. It connects with my iphone and plays music at a safe level while still being able to hear voices.

As soon as we started shooting, they did their job. I did have some issues with the ear foam not fitting well.

My only complaint is that I wish there was a size between the smallest ear foam and the medium ear foam. The medium was just a bit big, but it would be impossible the have a foam to fit EVERY SINGLE EAR.

That being said, I would still purchase 100% and have already recommended it to my LEO buddies.
