My beloved Bose AEs have semi-given up the ghost on me. I'm distraught.

Looking at some Harmon Kardon wireless ones for about £220 as a replacement. They look fucking ace but sound quality is important. I don't like the 'real' sound of brands like super.fi and to an extent, Shure. I prefer a warm low-end and clear highs.

Any experience with Harmon Kardon stuff?
