ReZound Frequently Asked Questions

Gamify Recycling with ReZound

Recycling never sounded so good!


How does it work?

The ReZound uses sensors that detect when a piece of waste goes by and triggers a sound from it's customizable sound bank.

How long does the battery last?

With two sensors plugged in the ReZound can keep detecting waste for up to 5 days before recharging!

How long does it take to recharge?

It takes about 8 hours to fully charge the ReZound

Can I customize the color or look of the ReZound?

At the moment, no. Only the sound files can be customized.

Can you customize the sound files for me?

Yes! If you purchase an order of 50 or more ReZounds we can create a custom sound bank for you. For smaller orders a small fee will apply. Reach out to for pricing.

Can the ReZound detect if someone puts in something that's not recyclable?

At the moment, no. Since there are so many different types of waste, and in particular plastics, it's hard to tell what's what, but we hope to help detect glass, metal, and paper soon.

How does the ReZound help recycling?

The ReZound works off a concept called gamification that aims to make recycling fun. By turning recycling into a positive experience we can encourage people to recycle more.

What can the ReZound do for me?

The ReZound can be a great avenue for promoting your commitment to recycling and creating positive interactions with customers and employees. The ReZound has potential as a tool for marketing, education, and gamification all wrapped in one!

Does this work in my Zero Waste Box?

The ReZound is only recommended for the large Zero Waste Box. Smaller Zero Waste Boxes may cause detection issues.

Will this detect all types of waste?

The ReZound will detect anything larger than a bottle cap. Smaller items may require a smaller opening to direct the waste towards a sensor.

What bins is this compatible with?

The ReZound will fit inside any bin larger than 10" x 10" and can be used with a 1, 2, 3, or 4 opening bin, though it is recommended for 1 or 2 opening bins.

How do you install it?

The ReZound is easily installed with double-sided adhesives that securely stick to recycling bins without damaging them.


Functionality Issues

I plugged in the sensors, but no sound is playing / the ReZound isn't triggering when I put in waste

  • Make sure the ReZound is on (indicated by the red light near the power button) and charged.
  • Check that your sound files are named "0001", "0002", "0003" etc, and are mp3 files.
  • Make sure the green light on all sensors are lit. If a red light is on, something may be obstructing that sensors and you will need to reposition.
  • The ReZound is designed to detect objects larger than a bottle cap. Smaller objects may occasionally be missed by the sensors.
  • The ReZound has a range of 8" which may cause issues with large openings in which case your Sensor Upgrade pack can help by providing additional sensors to increase coverage.
  • If the ReZound still doesn't work, email Design at
