I *love* Hear!
It's a great product that does exactly what it portends to do: get great sound out of crappy speakers..
The only (big) problem is that it doesn't work with Safari, so, i have to admit that i checked out the competition: i installed Boom 2, which does work with Safari..
*However* Boom 2 introduces a nearly 0.5-second delay in audio, which is fine, unless you're watching video, in which case, it's unbearable..
So, long story short, i (happily) re-installed Hear!
i'll deal with the no-Safari thing, as i have before, but, at least, i'm now again enjoying videos with great sound and no audio delay issues!
Hope this helps!
PS: i know that you can adjust audio sync in VLC, but you can't watch everything in VLC..
