Your new SoundOff noise masking product consists of:

Important: Before initial use, it is important to fully charge the batteries.

Charging the Battery:

Initial charging time for your new SoundOff batteries is approximately 1 hour. After that, the charging time varies depending on the battery state.

Plug the charger cord into a 120 volt outlet. Insert the small single pin end of the charger cord into the charger case.


The LED indicators will now glow red.

  • Insert each of the ear pieces into the charging docks in the charging case. Each earpiece is marked “R” for right and “L” for left. The charging docks on the charging case are also marked “R” for right and “L” for left.
  • earpieces2
  • Once the earpieces are correctly inserted in the charging docks the LED indicators will change to a flashing green. This means the earpiece batteries are charging.
  • When the LED indicators change to a steady green glow the batteries are fully charged.
  • Although the SoundOff batteries are designed to last for 10 to 20 hours (depending on the volume setting) of use before they need to be recharged, we recommend nightly users reinsert the earpieces into the charger docks every morning when getting out of bed. This way they will always be freshly charged for the next nights’ sleep.


Do not keep your SoundOff earpieces continually charging over extended periods of time without using them. This may permanently reduce the charge capacity of the batteries.

Important Comfort Tip: For those who sleep on their side SoundOff users have found sleeping with their ear placed in the gap created by placing two pillows together will relieve any pressure on the ear from the SoundOff earpiece. This works very well for those with sensitive ears.

Instructions for Using Your SoundOff Earpieces:

Putting on SoundOff earpieces

To use your SoundOff earpieces simply put the ear hoop of the left earpiece over your left ear and the right earpiece over your right ear. They can only go on one way. You can now adjust the fexible ear hoops to fit your individual ears.

Turning on SoundOff / Volume Control

Once you have found a good fit press and hold down the on/off button until you hear pink noise. If you push the button again but do not hold it down, the volume will go up one level; push it again and it will go up another level. There are six (6) volume levels. If you keep pushing the buttons the earpiece will simply cycle through all six levels and start over again.


Turning Off SoundOff

Once you have found the level that works for you, turn the earpiece off. To do this, just push and hold down the button until you do not hear pink noise.

The SoundOff earpiece will remember the volume level it was set at when it was turned off. When you turn it back on it will return to that level. You do not have to continually set the volume to your preferred setting.

Now you are ready to use your SoundOff earpieces. When going to bed just put the earpieces on, turn them on and relax to the soothing sound that will help you to sleep.

Care and Cleaning:

The SoundOff silicone comfort tips may be removed and cleaned as needed with cotton or tissue using alcohol or mild soap.

Do not spray or submerge the SoundOff earpieces with any liquid including water.

Using SoundOff:

The SoundOff noise masking product is designed to effectively mask sounds that prevent or interrupt a persons’ ability to sleep such as snoring or other bothersome noises in the environment. These patented earpieces are specifically designed to be extremely comfortable while worn during sleep. After a few days you will hardly know they are there.

You’ll love what you can’t hear.

Pink Noise:

The sound technology used to mask noise in the SoundOff product is called pink noise. Pink noise is engineered to mimic the pleasing natural sounds occurring in nature. It closely matches the sound spectrum of what we hear in our everyday lives like the rustling of leaves, a waterfall or rainfall.

Research has revealed that study participants experienced more restful sleep while listening to pink noise. This was attributed to the fact that pink noise slows and regulates brain waves.

Clearly, millions of people need both more and better sleep. Adding pink noise to your sleep routine may bring you closer to a good night’s sleep and feeling refreshed in the morning.
