Hmmm, higher SQ than the SA6? I might have to check it out, if only for kicks. Amazon has them with no shipping, for Prime members (but they don't ship for 3 weeks). Plus, a 30-day return policy. I won't ever abandon my Sleeks, since I really do love their sound and am looking forward to the wireless option. But I may have to sell off some other phones (716s, for example), to fund an SF5 purchase. Never owned UE before, and always interested in trying new flavors. And if I don't like them, back they go.
