Psi Earplugs

I created the Psi Earplugs because I couldn't find anything else good enough: 

best in class hearing protection that doesn't get lost. 


Pre-Production Prototype Testers:

We have 15 pair of each material available. We are releasing these to get feedback on form, fit, and function. They may (or may not) represent the final design. If you purchase these plugs we'd greatly appreciate your feedback.

Preliminary Lab Testing (ANSI Standard) : ~ 29db NRR


PSILENCE IS GOLDEN

Psi is the Greek letter commonly used in physics to to denote a wave function. 

My main problem with earplugs is I'm constantly losing one half. Doesn't matter if they are cheap or expensive, if they don't stay together, they get lost. Not really convenient when you really need them. I don't like pouches/cases because it's not convenient. Being inside a pocket (and then inside a case) are barriers to just grabbing my plugs and putting them in. Barriers mean I don't always use them when I should. 

Sure, there are other corded earplugs (mostly cheapo ones) on the market but the cords are usually PVC and so springy that the plugs don't hang properly or stay tied. Tying earplugs is also way 2009. Lose another pair much?


The two biggest complaints about hearing protection -- Go ahead, google it, I did. 

  1. Losing Them: little things are easy to lose. It's even harder to keep track of pairs. You don't want to lose your earplugs because when you need them, you NEED them. #thereifixedit with some magnets and a string. I'm no genius, but I know what works. 
  2. Crappy foam tips: they can fall apart, they can be too hard. In developing the Psi Earplugs I tested nearly every brand/model a normal human can buy. The people were right, other foam tips tend to be terrible. If they are too hard they hurt. If they rebound too quickly, you can't even get them into your ears before they spring back open. If they rebound to slowly..well that's just annoying. 

      Included with your purchase: 

      1. One pair of earplugs in Titanium or Delrin
      2. 24" of cordage you'll need to cut/tie yourself. Don't worry, if you can tie your shoes you've got this.
      3. One pack of S/M/L Comply Foam "P Series" canal tips

          My solution isn't rocket science, it's good design:

          Machining: I'm a machinist with a titanium fetish, so of course I machined the first set out of 6Al/4V domestic Titanium. It's light weight and completely hypoallergenic. We are also making an even lighter weight Delrin thermoplastic version which is great for cold temperatures (less thermal conductivity) and non marring if you work around delicate stuff and can't afford to scratch it up. 

          Magnets: Small (but strong) neodymium magnets pressed into each half snap together smartly and stay put. Period. Your plugs will be right where you left them, around your neck. They are also super fun to play with. Fidget freely. 

          Cordage: We are using a premium 1mm micro cord that allows the cord to drape naturally (like it should) when wearing the plugs around your neck. It's not the fanciest solution, but it works the best. You tie each end with a simple overhand knot, slip it around the waist of the plug, and snug it down. It's easy to remove and you can cut the cord to the exact length that meets your needs. 

          Premium foam canal tips: Comply makes a special line for hearing protection (P Series) and that's what we are using. They are manufactured in the US (really) and making the best foam tips is their one and only goal. Some of the fanciest companies who make things you stuff in your ears spec these tips...because they are the best. I don't mess around, remember? ;)

          Maximum Noise Reduction
          With longer length than standard eartips, Canal Tips are engineered to create a custom, deep in-ear fit for maximum noise isolation. 

          All Day Comfort
          Made from unique breathable memory foam, Comply™ Canal Tips are activated by body heat, becoming ultra soft, reducing irritation and fatigue. Comply™ Foam is 30x softer than silicone material.

          Stay-In-Ear Fit
          The length and tapered design of the Comply™ Canal Tip allows for easy insertion and stability in the ear canal, providing in-ear retention to keep communication devices in place.

          Flexible Threaded Core
          Special tapered core is designed for deeper insertion into the ear canal. Elastomeric cores have a molded-in screw thread for secure attachment to the communication device and soft durometer for comfort.


          Notes worth reading: 

          1. All foam tips are consumable: meaning they wear out eventually. The more you use them, the faster they wear out. If you get them wet all the time (sweat or otherwise) they will break down faster. I use mine every day, and I replace them once...maybe twice a year. 
          2. Replacement Tips: We provide a 3 pack of S/M/L size tips. Once you figure out what you need, you can just buy 6 packs (12 tips) from the Comply website. We hope to carry individual sizes eventually, but right now we only have the variety pack. 
          3. Tip Sizing: Tips come in S/M/L. No one will tell you this, but you can increase the protection level by packing a larger tip into your ear canal, as long as it still fits properly. Conversely, if you need less protection, you can use a smaller size. The comply tips are incredibly compressible. So I use a medium tip most of the time, but I can get away with either small or large. You can't do this with harder foam tips. 
          4. Sound attenuation: 95% of attenuation is provided by the foam tips. The base material doesn't really matter...despite the claims made by other companies. Attenuation is related to the density of the foam and the length of foam the sound has to travel through. This is why smushing a bigger tip into your ear increases protection...only up to the point where they still fit properly. It's also why the P Series tips are twice as long as a normal foam tip. 
          5. Lab testing & Certification: the earplugs we have right now are undergoing 3rd party lab testing. Preliminary results are around 29db NRR. We will publish final results when available.
