How to prepare saltwater
The saltwater is a crucial component in maintaining the required conductivity when using the headset. The salt ensures that the electrical contact between the headset and your head stays consistent throughout your session.
The amount of salt is important: too little salt will result in a low contact between the electrodes and the skin, too much salt can cause irritations on the skin. We, therefore, recommend starting with 1/4 teaspoon of salt for the bottle provided with the headset, following the refill instructions below.
1. Remove the screw cap, and fill the bottle with drinkable water.
2. Add 1/4 teaspoon of regular kitchen salt to the water.
3. Screw the lid back on, and shake the mixture.
For the saltwater to have an effect, it needs to be +0.6% NaCl - meaning at least 6 gram per 1 litre of water. This equals as little salt as 0.6g in the bottle provided with the headset. To achieve this, either mix 1 teaspoon to 1 litre of water (and then use this saltwater), or use an exact measure to add 0.6 gram of salt to the saltwater bottle.
Can I buy saline solution instead?
If you prefer, you can purchase premixed saltwater (‘saline’, or ‘saline solution’) at most pharmacies/drug stores. Standard saline contains 0.9% salt (0.9g per litre, NaCl 0.9%), which is a higher salinity than strictly necessary. The only potential negative effect of this is potential discomfort under the electrodes, as described above. if you buy pre-mixed saltwater/saline, make sure it only contains water and NaCl (salt).
