A:AnswerIf your 70v 25v PA amp has a 3.5mm headphone jack or some type of audio input that can be interfaced some way, yes. If not no. This plugs into the USB C on the phone and assumes to role of a 3.5mm headphone jack on previous Samsung cell phones. Hope this helps..
A:AnswerNo, the Xbox one controller does not use USB-C so this will not work, however a set of earbuds with a built in mic or a gaming headset should do just fine.
A:AnswerWhile technically yes this would work as it is USB-C, the dongle is intended for phones without a headphone jack, since the galaxy S8 still includes a headphone jack on the phone this dongle is not needed.
A:AnswerIt is better to use Bluetooth for your car. You may get away with using the USB port and if you have Android Auto or Apple Car Play that will take over the USB port in the car and control the radio and pass audio to the speakers instead and act as the media player.
They will likely not work to convert a USB-C on your car to 3.5mm if the car doesn't have 3.5mm audio in. The USB in via Android Auto or Apple Car Play will cover that if you have the feature.
A:AnswerI just tried it on my Switch, but it didn't work. The audio continued to come through the external speakers, it did not change to the headphones. So this would not be a the solution you need for you switch unfortunately.
A:AnswerI bought the DJI Osmo Action and this adaptor to connect a microphone but this adaptor DOESN'T work. You have to buy the CYNOVA 3.5 mm adaptor to connect a microphone to your DJI OSMO ACTION
