Pros & Cons-Earpiece is comfortable but fell off too easily and is now lost. (I didn't know they even CAME off)-The on/off button is very resistant and required two thumbs pressing VERY hard to activate.-Very slow to sync with phone after answering call. 1-3 seconds of delay is enough for callers to give up and hang up.-It's got a big butt, but still comfy to wear.-I will be ordering another 220.
