ISOtunes Sport DEFY Slim – Bluetooth Hearing-Protection Shooting Earmuffs

As all gun-owners obviously know, guns can be quite loud. In fact, not only do the decibels (i.e. noise-level) of a gunshot easily exceed 85 dB, but gunshots from most firearms can also exceed 130 dB, which is the noise-level for a person’s threshold of pain related to loud noises. That said, almost any gunshot noise can potentially damage your hearing. As such, it’s extremely important to keep your ears protected when handling and shooting guns so that you can ultimately preserve your hearing health. Now, one of the best ways to keep your ears protected in order to reduce the damage caused by loud gunshot noises while you’re target practicing or even while hunting is by wearing adequate ear protection, such as electronic hearing-protection earmuffs for example. So, if you’re looking for a reliable pair of hearing-protection earmuffs that can keep your eardrums safe from loud gun noises, then the ISOtunes Sport DEFY Slim are a great choice for you to go with.

The ISOtunes Sport DEFY Slim are ultra-comfortable electronic hearing-protection earmuffs for shooting that feature a IPX4 Resistance Rating, Active Gunshot Noise-Suppression of 21 dB, a Background Noise-Dampening Microphone, built-in Tactical Sound Controls, Bluetooth 5.0 Connectivity, and up to 25 hours of battery life.

Designed with hearing-health and safety in mind, these electronic hearing-protection earmuffs offer you (and your ears) superior protection at any time you’re looking to shoot a few rounds. By using the ISOtunes Sport DEFY Slim, you’ll always be able to easily align your sights with pretty much any gun, and all that without ever sacrificing your safety.

Now, let’s have a more detailed look at these electronic hearing-protection earmuffs and check out their design and also talk a little more about everything they have to offer you.

DESIGN & SPECS

Starting with the earmuffs’ size, the ISOtunes Sport DEFY Slim feature an ultra portable design, coming at a fairly compact size, and they’re also very lightweight, weighing just 0.68 lbs. / 10.93 oz. (310 g).

In fact, the ISOtunes Sport DEFY Slim were specifically designed to weigh around 0.22 lbs. / 3.52 oz. (100 g) less than several other models of hearing-protection earmuffs. That ultimately ensures that you can always have a great performance when wearing them for pretty much any sort of shooting activity, whether you’re simply looking to go pop-off some rounds at the shooting range, or even while hunting.

On top of their ultra-light weight, these electronic hearing-protection earmuffs are also extremely comfortable, as they come equipped with highly-adjustable earcups that make them fit pretty much any head-size, and their earcups also come very well padded in high-quality leatherette.

In addition to their leatherette earcups, the ISOtunes Sport DEFY Slim also come equipped with a well padded fabric headband that makes just as comfortable at the top of your head as their earcups do over your ears.

In sum, these electronic hearing-protection earmuffs are both lightweight and extremely comfortable to wear all day long.

Best of all, they’re also rated to have a IPX4 Dust- and Water-Resistance Rating that makes them capable of withstanding even the toughest conditions. Essentially, the Sport DEFY Slim’s IPX4 Rating qualifies these hearing-protection earmuffs as resistant to both dust and water-splashes, which for the latter, includes both your own sweat as well as soft rain-drops (not heavy-rain).

AUDIO SPECIFICATIONS & AUDIO QUALITY

Moving on to the earmuffs’ audio specifications. In terms of their hearing-protection values, know that the ISOtunes Sport DEFY Slim work based on a proprietary SafeMax Technology that helps to limit any of the surrounding / outside volume to 85 dB, and that ultimately ensures that you can hear all day long and without experiencing any hearing damage while wearing these electronic hearing-protection earmuffs.

Moreover, and as said before, the Sport DEFY Slim are also rated to have a Active Gunshot Noise-Suppression of 21 dB, meaning that they’re qualified to have a 21 NRR (Noise Reduction Rating) – which in EU terms translates to a 27 SNR (Single Number Rating) as tested and approved to the ANSI s3. 19-1974 Standard (a worldwide method used for the measurement of Real-Ear Protection of Hearing Protectors and Physical Attenuation of noise-protection earmuffs).

On a side note, and as every gun owner should know, it’s important to mention that the noise-level of most gunshots tends to be registered between 150 to 170 dB, which obviously, can easily and very quickly damage your hearing.

Nevertheless, thanks to the combination of the ISOtunes Sport DEFY Slim’s SafeMax Technology with their Active Gunshot Noise-Suppression of 21 dB, users can effectively avoid those dangerous gunshot noise-levels in order to keep their hearing-health well protected at all times. In other words, you’re guaranteed to be able to shoot safely all day long while wearing these hearing-protection earmuffs.

Last but not least, the port DEFY Slim also come equipped with a Background Noise-Dampening Microphone that allows for a clear communication at all times, even when you find yourself in really noisy environments (like crowded gun ranges with a lot of people doing target-practice). Thanks to that, you can easily stay in touch with anyone.

INTERFACE / BUILT-IN CONTROLS

Then, in terms of the earmuffs’ interface, these also come equipped with built-in Tactical Sound Controls, which are powered by a proprietary Sound Technology that amplifies any of the sounds you want to hear up to eight (x8) times of their natural volume, all while still protecting you and your hearing-health from harmful muzzle signatures (i.e. gunshot noises) or any other extreme / loud impulse sounds in less than 2 milliseconds.

Note that the earmuffs’ built-in Tactical Sound Controls can be found integrated at the very center of their left-side earcup.

CONNECTIVITY

For their connectivity, these electronic hearing-protection earmuffs boast Bluetooth 5.0 Connectivity, which is used for establishing a wireless dual connection with other Bluetooth-enabled devices (such as your Smartphone) over distances of up to 29.52 ft. (9 meters).

BATTERY & BATTERY LIFE

Finally, for their power, the ISOtunes Sport DEFY Slim utilize two (x2) AAA batteries (for which a set already comes included in their package), and these batteries can provide the earmuffs with around 25 hours of battery life.

FINAL THOUGHTS
