In-Depth Review

Now we will get into the nitty-gritty details of all the Liberate Plugfones have to offer, the good and the bad. I’ll spend some time on each of the important factors and features you need to consider when purchasing a pair of Bluetooth hearing protection devices. If you’d like to know more about each of these factors in general, please have a look at this article:

What to Consider When Purchasing Bluetooth Hearing Protection

Liberate-4.0-Bluetooth-Plugfones-with-Mic---EarbudsNoise Reduction Rating (NRR)

When used correctly the Liberate Plugfones offer a solid NRR rating of 26 which will protect your ears in most noisy environments. They offer more than enough protection for a range of activities and environments from the race track to your woodshop. They’ll even be good enough for most industrial settings…and even to block out your snoring spouse!



Battery Life

According to manufacturer information, when fully charged the Liberate Plugfones should last a solid six hours, which should be enough to get you through a solid day, especially if you are able to give it a quick charge during lunch or breaks!

That being said, many reviewers on Amazon suggest the battery life is more on the side of 5 hours. If you’re looking to use them a full work day without charging them, you will most likely run out of battery midway through your day. However, you could easily purchase two sets and alternate them, or simply ensure that you’re charging one set at every opportunity.

Bluetooth Abilities

These earbuds come with a 4.0 Bluetooth antenna which will ensure maximum clarity, quality, and speed when connected to any Bluetooth device. Given this, the range would be similar to any other Bluetooth device. If you leave your phone in your pocket or nearby (within 10-15 feet) while listening you shouldn’t have any problems with connectivity.



There is a noise reduced in-line microphone built into the cord for making and receiving phone calls. This is a handy feature since it allows you to answer an incoming call or place an outgoing call without needing to take your phone out of your pocket or your earplugs out of your ears. You are able to chat hands-free and continue your work without exposing your ears to your noisy environment.


Liberate-4.0 Bluetooth Plugfones with Mic - BackSound Volume/Quality

The speakers are nothing to brag about, nor are they anything to complain about either. They’re comparable to any other set of well-made earbuds.

There are built-in play/pause, volume up/down, and song progression buttons on the control box. Unfortunately, they are a bit awkward to use since the controls end up being behind your head while you’re wearing the Plugfones. If you want to adjust any of the controls you’ll have to reach behind your head and hope you’re pushing the right button!

Size & Comfort

Liberate-4.0-Bluetooth-Plugfones-with-Mic---EarbudsAs I mentioned in the beginning of this review, the Liberate 4.0 Bluetooth Plugfones were designed for comfort first and sound second. They great news is, they are pretty comfortable and you shouldn’t have a problem wearing them for long periods of time.

There are two different earplug designs each from different materials (Silicon and Foam) to ensure that you can have the fit that’s just right for you. You should expect to receive two sets of each when you purchase your own Plugfones.

There is also an option to choose a cord length of 14 or 18 inches to ensure you get a set that fits you best.



Liberate-4.0 Bluetooth Plugfones with Mic - Earbuds-2Durability was first and foremost in the minds of the creators of the Liberate Plugfones. They use a replaceable tip design which allows you to easily replace the memory foam or silicone earbuds. Replacement earbuds are included with the original purchase. It is also extremely easy to purchase multiple replacement earbuds at an affordable price.

The set is fully sweatproof so you don’t have to worry about ruining them during a workout and the USB charging connector is water resistant as well. That being said, it’s not waterproof, so it might not be the best idea to wear them in the midst of a downpour!

The Plugfones come with a zip-up carrying case to help you keep track of and organize the headphones and replacement earplugs that come as part of the original purchase.


The Liberate 4.0 Bluetooth Plugfones are available to purchase on Amazon for the price of $109.99 plus¬†shipping and handling. This is a bit more than some similar earplug style Bluetooth enabled hearing protection headphones, but given the high-quality construction and materials plus the battery life, I don’t think the price is that bad at all.

In addition, you are able to buy replacement earplugs at a price of $10.99 for five pairs.



Liberate-4.0-Bluetooth-Plugfones-with-Mic---Working-OutTo finish up I think the Liberate Plugfones are one of the best options out there for earplug style Bluetooth enabled hearing protection devices. They are very durable while maintaining their comfort over long periods of time. They can be used safely in a variety of environments and won’t ever get in your way. They are lightweight and a lot less bulky than big earmuff styles hearing protection devices.

If you’re looking for a great option to keep your ears safely entertained while you work, exercise, or even sleep, then I would highly recommend the Liberate 4.0 Bluetooth Plugfones!
