I purchased both these and the Jabra BT8010 to try with my Qwest Mogul. I must say that the Lubix is head and shoulders above the Jabra for me - all the functions work properly with my Mogul, while none of the extra features work on the Jabra. The sound is very good on the Lubix, and I really like the various audio enhancements - I like the "mex" setting the best.The only problem I have is that the earbuds are a little large for me, so I'm ordering a set of the Jabra eargels to try with the lubix headset. I do notice that the fit is very important to the perceived sound quality - if I hold the lubix to my ear, the bass is incredible. The Jabra BT8010 earphones just don't fit my ear properly, as my left ear is a little smaller than my right, so the phones end up pointing different directions. All in all, the Lubix works much better for me. I very carefully took the units apart and shortened the wire loop to the correct length for my head, also I redrilled the microphone hole to make the sound pickup better. After these modifications, the unit works perfectly for me.
