Q: 3 d glasses
A: No, 3D glasses are not included.
Q: Does this TV have built-in wireless or does it need to be hard wired to a router?
A: Has built in wireless, but because of the size of 4k content all of these tvs stream 4k content better hard wired. I have streamed non 4k wirelessly without a problem, some 4k on Netflix I pause the program for a couple minutes which lets the stream get ahead of my playback.
Q: Does it have or can WiFi be connected to it.
A: Yes, this product does have wifi.
A: 110 to 120 in the United States. If in another country where it is different they are designed to take different voltages. Yes you need 3D glasses and I do not think they are provided. At least not with mine. They use active ones. Sony warranties are the best in the business bar none.
Q: Is it necessary to use 3D glasses when watching the tv for any programs, movies, etc.?
A: It's not necessary to use 3D glasses, all that happens if you don't use them is you see the programming in 2D, just like a regular TV. The Sony 75 Class LED Smart 3D - 4K Ultra HDTV is still an excellent choice.
