@Gabriel - first of all sorry for the late reply. I got a tattoo today and just slept for few hours.
I experimented another in the lead up to the road trip. I bought Sony, and Monster ones, so the top brands. They were good, don't get me wrong. But the cheapest pair were way better in terms of noise cancellation. I'll link the ones I used on the road trip. I used both these and Monster ones to see the difference and there was like 5 percent more cancellation with the cheaper ones.
Here's the link:

I've noticed they upped the price to 50 but they also offer a 15 pound voucher
