Cyrus blaming the popping sound on the phone (wether android or iPhone) is a complete lie since this sound does not exsist on other DACs played through these same devices. It's more of Cyrus not bothering to make this device compatible with phones. Yes it plugs in but there's oblivious coding and grounding issues when plugged into a phone. I asked Cyrus this question several times while the kickstarter fund was going on, I received no answer from them except that it might not be directly compatible so I decided to cancel my funding. So Cyrus knew this device was going to have limited compatibility and still decided to release it since it would have been too costly and time consuming to make the device more compatible like a dragonfly or many others. If people read the question/answer area in the fund section they would have seen Cyrus's responses. I personally emailed Cyrus as well, since I am a customer previously and I only received the same generic response, it might not be compatible with all mobile devices and most devices will require a separate cable to be attached. Cyrus wouldn't even answer if it was going to be compatible with an iPhone or if there would be connection issues, only answer was that it required a separate cable. The reason I hate these fund me options, no testing on the product and if it sucks the manufacturer already has their money with no recourse since it's not a purchased product but a funded project.
