3D Design Brief
I'd like to design a stylish and modern earplug that looks distinctive.
I am looking for ideas that people will be proud to wear - on the train, at concerts etc.
The closest competitor I've found is LOOP Earplugs. However, instead of a circle, I'd like it to be a heart shape - this seems more ergonomic to the shape of the ear and will look more unique.
Please design the following:
- Earplugs: taking the simple design in the attached images, but updating the circle to a heart
- Case: Please create a simple case for the earplugs to go in. These should easily be able to be thrown into a purse. They should look modern, but also unique.
There is no brand name for this.
Can't wait to see your ideas!
Target Market(s)
Millennials (20s - 30s) who are getting older and starting to be more conscious of their hearing and keeping it in tact.

Requirements
Must have
- Unique and discreet earplug idea. They should be a stylish alternative to the squishy foam ones. Besides wearing these out and about, they also need to be comfortable to sleep in.
Nice to have
- I think it would be cool to have levels of noise reduction, so like: Low, Medium, High. Depending on whether you still want to hear some things (for example concerts) versus when you want no sound (like sleeping). It could be cool to see this integrated into the designs or packaging, but it is a nice to have. I would also like to have a 'kids version' of the product that is a bit more playful and youthful. With a smaller design.
Should not have
- Whilst I love the LOOP design, please just see it for inspiration, I'd like a unique design that looks a bit different to this. Also, no technology aspect to this.
