I've had these for 2 weeks and think they are better than their Samsung equivalent! They just seem to fit better and my wife likes the styling much more. As far as x-talk and/or ghosting? Maybe slightly better than my Sammy 2100 series. I don't believe they get as dark as the Sammy's when activated. I have had ZERO issues w/ losing sync, but haven't bad a problem w/ the Sammy's either for the most part. I'd rate them 5 outta 5 stars!
