Indeed, 7056 is the "industry standard" for location work.

But Sennheiser 380 Pro is a closed back design and more than fine to use. Go for it!

As for earbuds? No.
Only people you'd really see using them are camera hops who are just doing very basic monitoring to get the gist of what is being recorded internally to their cameras.

There ARE professional-grade earbuds. The most well-known brand is Etymotic Research. They make hearing protectors (ear plugs) as well. For example: https://smile.amazon.com/dp/B000XPG2QI
Many serious users have custom ear-molds made for them by a local audiologist for comfortable all-day use.

Some people in high-noise situations use a combination of ear-buds and military-grade hearing-protector "ear-muffs" The most prominent brand is David Clark. For example: https://www.amazon.com/dp/B0049C71KM/dvinfo09-20

Sony MDR-7506 are the gold standard. I include earbuds as a backup but they don’t isolate as good as over the ear headphones. It sounds like you want to use earbuds, It’s not to say you can’t Richard points out the custom ones but they are expensive and designed for on stage performers who can’t wear headphones.

Re: Monitoring headphones
 

I use Sony 7506 with my XF-300 and digital audio recorder, but I use the Shure 215s when recording with my iPad Mini. The Shure's do an excellent job of blocking external sound with properly sized and fitting ear seals.

Just to update this tread, I did get the Shure 215s and they are fine for me to use when I'm recording. For editing I'm sticking with my HD 380 Pros. By the way, I also have HD 280 Pro.
