It does what it claims to do in that it makes the music sound like it’s coming from a set of speakers a few feet in front of you in a room that has poor sound deadening. I really tried to like it but it just sounds more muddled/is fatiguing for me.

Edit: I haven’t tried it on acid yet tho, maybe that would make it make sense.

like @zaphod said, its mostly to make it sound wider. in mono, everything sounds like its in the center of your skull. in stereo, some stuff it a few inches from my ear (wherever the drivers are), some stuff can be in my head, some can even be in my throat if that makes sense

Things like Spotify or your phone/earbuds themselves usually have a mono setting. I use it all the time when only wearing one earbud. Beatles songs are notorious for splitting vocals to one ear only.

The solution is already right there. But let me guess, "No, I want to use my old wired earbuds from 1995 and they should accommodate me in my archaic niche use case instead of me upgrading my earbuds to enjoy the new features developed like forced mono"?
