Firstly, the sound quality is up there with the best on offer to date, clean and crisp with plentiful bass. I?m not a huge fan of Odyssey or Origins. I hear sounds as if Im NOT wearing them - people walking by, or talking etc. Pour les journées où je suis en robe. The fit is amazing. My right foot has arthritis and sometimes needs a bit more room. You know your getting quality as Corsair is a good brand with a built reputation. It is compact and holds the spice bottles securely. Sound quality in wireless mode vs wired can be massively different, especially when it comes to instrumental music (and especially string based instruments). It seemed that there were ALOT of cheap sets that were just as good, if not better then alot of the more expensive head sets.
