What type of headphones are best to use?

I do not endorse any particular brand, but can say that enclosed headphones with a frequency response of 40 hz – 16 khz work best. I will also say that while mixing TTM recordings, I use Sony MDR 7506 headphones. I find these comfortable and light weight. So if you wish to hear these recordings as I do when producing them, the cost is about 100.00 US per pair.
