A:AnswerHello Kat,
Thank you for sharing your inquiry with us. This Splitter Cable works only for audio out from a certain audio source and to divide the audio into two headphones. No, this splitter doesn't work with a mic.

A:AnswerNo because your two signals would combine at the same time. You would need to unplug one or the other to use it that way, one device at a time.
A:AnswerYes it does works perfect I thought I was gonna have trouble because of the USB but I just plugged into a block and connected it and it works great
A:AnswerIf your Surface Pro has a female 3.5 audio output jack, yes you could purchase the splitter cord and plug in 2 sets of headphones if each had a male 3.5 plug.
A:AnswerYes this should allow the connection of 2 similar male 3.5 mini jacked speakers.
Think of it as a Siamese connector, in effect one becomes 2. Ideally the speakers you use would be powered on their own for the sound output. They would have an AC power plug if they are powered or possibly an internal battery.
It is doubtful that the projector would have a large audio amplifier built in to deliver power to your speakers. I suggest that you buy this inexpensive splitter plug and try it.
A:AnswerNo, being an aux cable it won’t transfer that data to your iPad, however there is a cable you can get an iOS OTG adapter or get a powered usb hub then attach a usb c to lightning connector to your iPad which should connect a usb microphone
