The difference I PERCEIVE in using in-ear audio compared to speakers is incredibly dramatic. I can't speak for anyone but me, I don't know what you'd perceive. But for me, it's "night and day." I'm skeptical that any set of speakers can approach the clarity, imaging, the stereo effect, and in particular the treble I get using my Etymotic Research earbuds, of which I have quite a few sets, from their high end ER4S and ER4P to some lesser but still excellent in-ear products, cheaper, but not to-me noticeably inferior.
Now, the Etymotics are NOT wireless. The Sony's I have ARE wireless (Bluetooth), but AFAIK the sound isn't particularly inferior.
I can't say I'm an audiophile, in large part because my hearing is screwed up... too many rock shows in the 1980's and I have had tinnitus ever since. But my hearing seems to be pretty stable.
So, I could invest a lot of time and money into sound that doesn't involve headphones or earbuds but the easier (and I figure more sure fire) approach for me unless and until I can experience satisfactory speaker-driven audio that's comparable (not sure it's possible, honestly, but I haven't visited an audio showroom in decades!!!) is to pursue either Bluetooth or getting my audio through WIFI or just plugged into a cell phone.
I've had my hearing tested more than once and the profile they came up with had me basically normal up to 3000hz and attenuated something like 50% from there on up. It's been some years since my last test but I don't have reason to believe it's changed particularly since then. But I know my hearing isn't what other people's is. I have to ask people to repeat themselves sometimes in conversation because I don't pick up some words. I think other people hear things that are too faint for me. Still, I don't have the sense that everything is quieter than what other people here because I can easily have the sense that things are loud or too loud. I have earmuffs (more than one pair) that I use to protect my hearing. I use those not infrequently to protect my hearing if I'm bothered, i.e. at home.
The speakers in my kitchen are bookshelf Yamaha's (big for bookshelf) that I picked up discounted (I guess open-box) at Sears some years ago. I figure they are pretty decent. In my bedroom, I have Speakerlab, from kits I bought around 1980. They were reputed to be pretty "flat." I wanted speakers that would reveal everything in a recording. That was before I developed tinnitus.
