What are the best products to block excessive noise?

I'm a web developer working from home, but my next-door neighbours are pretty loud which makes it hard for me to concentrate. What is the best product (i.e noise cancelling headphones, foam earplugs, etc) or method to block noise while coding?

    Use Noisli + Bose Quiet Comfort headphone (I prefer the in-ear because they're better at blocking out sound).
