I've worked in both and I can't stand open office plans. You mentioned that you have your headphones in when you are busy, I did the same. I'm sure I contributed to my hearing loss because I had to cover my ears to prevent me from being distracted by my co-workers when I needed to concentrate. What about when I want to concentrate in silence? Can't do it.
Also open office "productivity" devolved into my co-workers being able to easily turn around and interrupt me constantly for trivial items vs. if there was a bit more friction in them getting my attention: walking to my office etc, they would go figure out the problem themselves. These two things were major reasons I hated working in an open workspace.
