Yes. For best results, please ensure that the location/s in your house where you use Optimum Bio Sound Therapy (e.g. bedroom, lounge, study, etc) has a strong Wi-Fi signal. 

You can test your WiFi signal (with a phone or laptop) using the following link: https://shorturl.at/T44MI

For best results you should see:

3) Ping: <150 ms

4) 4/4 bars of wifi strength at the top right corner of your phone
