I initially came across the Calmer product via a source that I usually pay no attention towards - Twitter advertising.
However, I’m acutely aware of anything that can assist with my younger brother’s daily issues with certain frequencies triggering incredibly debilitating, migraines (it doesn’t help that I communicate with him exclusively by blowing on a whistle for differing lengths of time - in a language entirely of my own devising, to be honest) and also, with me being the singer/guitarist in a band outside of GF (www.recluse.bandcamp.com), I’m only too aware of the long-term effects of poor ear-care combined with consistent exposure to loud volumes without due preparation.
And so I contacted Flare, who kindly sent out promotional units for us to cover.
I have to say that the results of using Calmer have been quite astonishing.
