Pros: Light weight, sound quality is perfect, music sound very good and the talk time is six hours which is longer than Jawbone, blue ant, and plantronics. I love the App>
Cons: Not really a con because I get email updates, but when the I Phone has a firmware update the 510 needs to be updated as wel. I guess if you want to use an App you have to get the updates, it does only take four minutes or so.
Excerpt: I updated my phone once and I accidentally deleted the earprint app, thankfully it’s available for free at the app store. If you’re a consummate caller and the bulk of your mobile usage is spent on making/answering calls, then owning a state-of-the-art headset like this will motivate you to call even more. The price though is a bit steep at 120 dollars. A good thing I got it free. Hence, I absolutely recommend it.
