Easy Walk (brand name) and front clip harnesses (general) they tend to make the dog not pull by virtue of 'turning' the dog around when they pull, so they wind up either facing you or sideways. The thing you're talking about is called a head halter/head collar more generally, with gentle leader being a brand name. Choke chains or unlimited slip collars.
The important thing to remember with every last one of these (or any other 'no pull' leash, collar, or harness) is every last one of them works by being aversive to the dog and every last one of them needs to be used with care and awareness of your individual dog. Every last one, you need to be aware that the tools are management, not substitution for training. They all have risks. Some of the risks are higher than others, but none are completely without risks.
For me, when dealing with this, I will advise anyone online to use a front clip harness and if that doesn't work to seek out in person help (for at least fitting and basic how-to-use) or just step up the actual training via different methods. The front clip harness is the one with a very low risk of fall out if improperly fitted or used, and in the absence of being able to see and know the person, I"m not going to advise them to use anything else.
