Received my QO earlier this month and it’s been a wonderful soothing meditation device.
Hearing ten minutes is a nice sound example, but the receiving and transmitting poles on it are really a trip to figure out. I like to sit with my hands on both posts (send and receive) and it’s cool to consider yourself being a small loop of reception and broadcast. Occasionally you’ll hear small events happen, like a crackle that floats around, or a muffled door shutting. All of this is the mind, of course, but it’s also audible, which happens with noise - the brain fills in details. I’ve also been surprised by sudden thoughts or solutions to problems that jump out in a session. I regularly meditate daily with a Mindplace Kasina, which can help train your mind for other meditation devices. Because of the Kasina, I think my dip into the QO was pretty quick and I like it quite a lot. It feels like swimming. I really prize the thing.
Also: If you want a more active QO, turn it on and place a Soma Ether on top and listen through the Ether. Suddenly, all the transmissions and reception are playable, and they combine to be a pretty effective playable/musical noise source.
