HT3 sound? They don't! They let you hear everything that is happening ahead of them, from the talent of the performer, the mics, the record electronics, down to the whole playback system, for better or for worse (usually for the better, a lot better, with good stuff ahead of them).
My HT3s are tools, my acoustic windows into the quality of our design ideas. We need to hear it all, and the HT3s let us know, right away, if our ideas are worthwhile.
Strongly recommended if you can afford them. If the price is out of range, think about the SongTowers. Both designs have that rare "magic" - the ability to just suck you into the music and disappear. This is almost impossible to design for, but when it happens you will know it
