Most issues with a headset relate around poor volume and dropping the connection after a pair. To quickly summarise:The volume could be louder but is better than the 3 other headsets I've owned. Most times, you need only adjust the volume between both the phone and headset to find a better combination.I've never had the connection drop...never. Once paired, it will connect to any of the 3 pairs allowed with the push of the button -- just as it says in the manual. How often does that work perfectly? Well, it does with this BlueAnt. Anyway, works great.One of the best things about this headset is the multi-use charger. It has a universal USB connection that separates from the car adapter and the home outlet adapter. Fantastic. Absolutely fantastic.Only con is that I wish the volume would get louder; however, I've yet to find another that exceeds this.NB - I use the Siemens SL75. No issues there, so don't feel wary if you're only reading reviews from people using your common Motorola/Nokia phones.
