What is WorkSonics?

WorkSonics is an iPhone app for people who work with or use noisy home and industrial power tools, such as Circular Saws, Jackhammers, Chainsaws etc, who want to, or need to, hear what’s going on around them without the fear of hearing damage. You can easily have a two way conversation and hear every word with no drop outs while tools are being used.

WorkSonics!® works with Apple standard iPhone earphones or earpods, worn beneath passive ear protectors, allowing power tool users to listen, talk and work with safety.

For enhanced protection you can use in-ear iPhone headsets like Sennheiser or moulded earpieces like Ultimate Ear and other UNDER your ear defenders.

WorkSonics!® uses patent applied for technology, to enhance quiet sounds like an colleagues voice, while reducing the sound of a tools to a small harmless buzz…

WorkSonics is a Smartphone App and of course cannot provide physical protection for user’s ears. To prevent hearing loss, users MUST ALWAYS wear over-the-head workplace standard ear protectors/muffs on top of earphones, to provide a physical layer of protection for their ears.


You must follow manufacturers instructions when using deep in-ear earphones or headsets such as Ultimate Ear, to get the full benefits of Double Hearing Protection.

Frequently Asked Questions

1. Can I use any other headphones?
WorkSonics may work with other headphones but only Apple supplied Headsets and Earpods for iPhone and iPod are certified for use right now. We have also tested Etymotic HF3 and a variety of other good quality in-ear headsets with microphone. Ultimate Ear moulded earpieces can add an extra layer of protection and comfort. See 2.

DO NOT use any earphones or headsets designed for Android devices, they may cause WorkSonics to malfunction with unpredictable results that may compromise safety.

2. Can I use moulded in-ear headphones like Ultimate Ear instead of wearing ear protectors?
NO. You MUST wear ear defenders over the top to provide the bulk of the protection. In-ear phones on their own do not provide enough protection. Using BOTH will increase your protection to around 36 dB NRR which is a useful improvement when working with heavy industrial tools.

If you are using non-Apple headsets and get feedback, just turn the volume down.

3. What happens if I choose the wrong tool preset?
WorkSonics! will work even if you choose the wrong preset however it may affect low volume sounds like speech if the wrong preset is chosen.

4. Will WorkSonics affect my iPhone battery life?
No. WorkSonics! has a minimal effect on iPhone battery life.

5. What about Android?
Due to Android OS audio problems, voices are delayed and echo. We will not make an Android version until these problems are sorted at OS level..
