I need a good night sleep. Is that what you are saying to yourself?
Would you like sleeping earplugs that are so small and well designed that you literally cannot feel them, whilst still attaining maximum sound blockage?
The GoodSleep, without question, is the cutting edge of sleeping earplug designs. It is the premier earplug available worldwide to combat noise related sleeping problems.
A sleeping earplug demands a small profile whilst providing maximum comfort and sound blocking ability. Traditional silicone/wax sleeping earplugs gather lint and other impurities whilst sleeping. This is definitively unhygienic and uneconomic in the long-term. Foam earplugs employ a one size fits all policy either too small for effectiveness, or too large and incredibly uncomfortable.
Our earplugs are produced from thermo-reactive elastomer: a soft, flexible material that matches your body temperature within 4 minutes, conforming to the unique bends, turns, bumps and twists of each individual’s ear.
Utilising the latest findings in ergonomic design and harnessing the power of thermo-reactive elastomer, the minimalist size of the GoodSleep leads to maximalised comfort, blocking sound whilst you sleep.
Key Features and Uses:
  • Thermo Reactive Material
  • Ergonomic Large Flanges
  • Unibody Design
  • SNR 30 - noise cancellation rating

Tested and Certified:   
Otifleks was developed and manufactured only subsequent intensive consultations from leading physicians and medical professionals. They conform to Australian and European Union regulations.

Use your Credit Card as sizing guide as shown in adjacent image. Do not measure your finger on your screen.

Step 1 Place your little finger into your ear to check how it fits. If the tip of your little finger is too large for the entrance of your ear canal, you should buy one size smaller than your finger shows on the credit card. If the tip of your little finger is too small and can enter the ear canal easily, buy one size larger than your finger shows on the credit card. If the tip of your little finger covers the entrance of your ear canal perfectly, then buy the size that your finger shows on the credit card.

Step 2 Place your credit card on a flat surface. Place your little finger on your credit card. Align your finger to the left of the first number on the card. Do not align it with the edge of the credit card, Note: make sure your finger just touches the card. Do not push your finger down. Then see how many numbers your finger covers.

Small: if your little finger DOES NOT exceed the first 3 numbers

Medium: if your little finger DOES NOT exceed the first 4 numbers

Large: if your little finger DOES NOT reach the 5th number

XL: if your little finger DOES exceed the 5th number.
