Q: Will the mic work when connected with cable to PS4 controller?

A: No unless you buy the usb to wireless connect to ps4 like the ps4 gold headset

Q: Do the headphones also come with a cord that will allow for the use of blue tooth or wired option? My dad would like to use these to watch T.V.. I'd like for him to have a non-blue tooth option as well as wireless. TIA

A: Yes it comes with a propriety cord which is 2.5 mm in one end. Unfortunately, that means you can't use any AUX cable, and have to rely on Senheisser's cables, which tend to be pricier, but it does come with one cable.

Q: does this product work well w/phones?

A: I tried it over Bluetooth, ant it worked well.

Q: Can they be used with a ps4? Considering the speaker and the BT connection, I figure it makes sense. If not, is there a usb - adaptor that will allow the connection to be seen from a ps4?

A: Yep, but if you choose to use the microphone as well then the connection bandwidth is very limited and the audio quality drops significantly. The only headsets that avoid his problem use a separate usb dongle and not bluetooth. I even tried using an aptx dongle on my ps4 and still microphone was a no-go. I got the PlayStation platinum headset and it works like you’d expect with high quality audio and microphone at the same time.

Q: Will they work on a Play Station 3 ?

A: Nope. Dont know why. I tried them but they dont work with ps3. Maybe with a dungle. But either way theyre great hedset
