I'm looking to get some high end bluetooth headphones. Something with quite good sound quality when over bluetooth and that also has a wired option for when I'm not moving around and can sit in one spot. Right not I'm looking at the Harman Kardon BT and AKG K845BT. Does anyone know how these two headphones compare? In both sound quality over bluetooth and in wired mode. Overall balance of the headphones (bass respose, recessed mids or not, etc). Also how does the comfort compare between them. I'm willing to look at other headphones too so if anyone has other suggestions let me know.
