Sony WH-1000XM4 wireless headphones for $228 (normally $350) at pretty much every store (Sony, Amazon, Best Buy, etc). Just got them and they are great but I never had wireless headphones. They do take 10-20 seconds to connect to my iPad, but that might be because they are also set up with my phone.

I considered the newer version but the reviews made it seem like it wasn't a huge upgrade and in some ways a downgrade, like the newer version doesn't fold to a smaller size.
