## Description

desertcart.com: HyperWhistle (Safety Orange : Sports & Outdoors

Review: Well, my tinnitus is worse; that is proof enough that this thing is LOUD! - I'll start by saying, do not be like me; this is not something to foolishly test out indoors, because, you easily run the risk of making yourself deaf, or, at least having some serious hearing damage. Don't be like me, and use this inside, as excited as you, rightfully, are, to test this the second it is delivered. I read, for a long time, what the "world's loudest whistle" was, and, found out about the Hyperwhistle. I can say, as the headline suggests, that this fits that bill, and then some. Pros: - This is easily the loudest whistle you can buy, so it is suitable for all sorts of applications. - Price is fantastic for what you get. - I tested this, on a long, pier, which is in a very rural area, with a friend, and the claims about distance, are accurate, if not a bit undersold; this could easily be heard much further away. - Does not require an immense amount of lung power to use, whilst still being ear-piercingly loud. - Unbelievably durable/well crafted - I wish more plastics/polymers were made to this standard, or, all were. This whistle can take a fall onto concrete from 3 stories, and it can be left outside (neither of those are anything I'd recommend), for 4 days straight, in a predominately saline environment, which does a good job at least tarnishing almost anything in less time, and, this shows NO signs of damage or anything; it looks brand new still after all of that. Cons: - I have absolutely nothing negative to say about this, and I have tried to find something.... - It isn't a "con", but, it sure would be nice, if this had the "NHL referee style" two finger ring guard, somehow implemented on future designs, or perhaps a variant product. The lanyard can do that job as well though. All said, this is a very very very, loud, whistle. I could see this being easily used for a means of self-defense, that would alert literally anyone, and buy someone time to escape whatever danger they are in. If more lifeguards had this - maybe they do use these, no idea personally - that also would be a very effective and affordable way to save lives, and, again, alert anyone on a beach. This is something that I would suggest anyone who wants to go hiking, or is into ANY form of exploration, be it nature, urban, etc. to have with them, as it really is tough enough to withstand anything, it CAN be used underwater (tested this myself, and even remembered to use earplugs), and, well, to avoid being more redundant, this could easily save your life, and it is so well made, that I've already been suggesting this to other people. I have nothing negative to say about it at all, because it's got the perfect price point for the quality, and accurate, if not modest, claims they make in their advertising for the product. 10/10 - 5/5 Stars - Excellent product, which I HIGHLY recommend! - RevengeOfThePiff
Review: Definitely the loudest whistle I've ever heard! - I ordered this for a mill & turn machine I run at my job, using the air blow feature and this whistle to notify me when the machine in waiting on me to do a tool check. As you can hear in the attached video, this gives a very loud report, even with other machinery running all around me and the door closed on the machine it's connected to! The World's Loudest Whistle? You bet!

### ⭐⭐⭐⭐⭐ SUPER LOUD, Must Wear Ear Plugs
*by J***E on June 21, 2026*

There’s a reason the whistle comes with included ear plugs. You can seriously damage your hearing with this whistle which makes it more difficult to use. Super loud and you get what you pay for. Whistle is durable, well made. Color is as described. Lightweight, yet it’s bulky. Obviously it’s water resistant you can blow it under the water it states. My only complaints is the bulkiness you can’t just casually wear the whistle around your neck for EDC unfortunately.
