Pros car kit because of audio quality!
Cons ear piece because it's only lasts about 300 charges!
Summary Salespeople may tell you that Bluetooth earpieces are the low-cost solution to hands-free calling -- but a closer look reveals these claims to be misleading.
Here is a list of disadvantages that the earpiece manufacturers and resellers don't want you to know about:
Nearly all Bluetooth earpieces have an internal battery that can't be removed. These batteries have a short life of approximately 300 charges, or approximately one earpiece per year (less if you recharge every day). And prices range from $20-$300, averaging about $50.
The earpiece can't be used while it is charging.
The earpieces don't fit everyone comfortably. One size definitely doesn't fit all; yet you cannot try the earpiece before you buy.
The earpieces are uncomfortable for those who wear glasses or sunglasses.
For reasons of hygiene, the earpieces should not be shared.
Earpieces are easily lost, stolen, or broken.
Bluetooth headsets, on average, last just 26 hours when not in use and only 2 to 3 hours when talking.
The life of the lithium ion battery starts to decline the day it was manufactured whether it is being used or not, the talk time and standby time will continue to degrade over it's short life. The advertised talk time and standby time is only valid when the unit is new and even then the claims are likely overstated.
Many users purchase more than one Bluetooth earpiece, then finally give up and buy an integrated Bluetooth car kit.
Potential harmful effects from radiation through the earpiece.
Most people find the earpieces uncomfortable and ugly, and/or experience lousy audio quality.
Many people will buy the earpiece believing it is more cost effective, ultimately they end up buying an integrated car kit because they just find it cumbersome to use.
For the person who talks on the phone for business or wants the best audio quality each and every second of their calls, there is no substitute for a Parrot hands free car kit. No batteries to die, no ear pieces to buy every year, even if you plan on selling your car in 5 years, your car will be worth an extra couple of hundred dollars because of the Parrot Bluetooth car kit option. The value propostion is clear as day, make the prudent choice!

Cons Sound repro clarity needs frequent adjustment
Summary IF my current car wasn't a Mazda MX-5 and IF I drive with the hood down and IF Parrot could use the 7 Speaker BOSE system and IF my hearing was not a 69 year old water polo playing surfer ex comp swimmer....WELL?
