#1 My headphones the audio has red and white cord what cord do i need ?
If you search online for vizio and model you can view the instruction manual/ user set-up that will provide this information. I know you can connect Bluetooth/cordless headphones but I have not tried to connect corded headphones. My TV is at home and I am not. This TV has had everything I have needed so far and at a great price.
The TV comes equipped with google cast and includes many free channels accessible by wifi/internet. If you have internet access no adapter is needed. For cable TV, you will need whatever your cable provider recommends/ requires.
Not sure I do not have a firestick. The TV does have an HDMI plug so if the firestick has that type it should work
#4 How do i setup my skullcandy wireless bluetooth headphones to this TV?
There is a menu to help you pair devices with the TV. I had to get close to tv to pair my cell phone. I have not paired my headphones yet but I know it can be done.
#5 Is this TV smart everything?, does it have hook ups for ps4 in the back?
Yes! It has the HDMI ports. It also will turn on with PS4. You can also use your TV remote to operate the PS4 as well.
