Works just great!

Doesn't work. Added it to extension and youtube shows the 440hz but you cant change it because its crossed out.

Absolutely fantastic extensions. It works like magic, adding Binaural separation between left and right channels and then creating a Hz difference to generate the illusion of the Binaural beat. Must have for people who want to get the most out of the music they listen to!

This is amazing! For the first time ever I can enjoy Binaural Beats while listening to any song on YouTube or YouTube Music! Remarkable!

I'm really glad that this Chrome extension exists. I use it almost daily for YouTube. When you set different frequencies, you can immediately hear a change in pitch with music. It takes a bit of getting used to at first, but after just a few seconds, you don't even notice it anymore—you just feel the effect of the frequency. I don’t notice any difference when it comes to voices. Best regards from Germany!

This is a huge step in healing the world. Thank you for this.

Love this extension. Makes listening to any song on Apple music so much better!

Super easy to install and to use! All the Solfeggio frequences to choose from. Just clicking though the different frequencies is quick and easy. I can listen to the music how I want to. I highly recommend it. Great extension! Love it!

The best way to retune any YouTube song to Solfeggio Frequencies and 432 Hz tuning! Works like magic ❤
