Cheaper than a Bluetooth headset, it enables the same functions.
You can make calls using the microphone is quite sensitive, even away from the mouth (much better than the speakerphone mode iPhone 4 in my case).
One can also control what is controllable with the original headphones (Siri, Spotify, Music, Calls, etc ...)
The cable is short (90 cm) and thick (but flexible), which allows not to bother when the phone is close to the car radio.
The sound is clean and the connectors do not sizzle.
The remote control works well, even if the click is a little too sensitive.
The jack works with the Apple bumper.
Compatible with a lot of devices (see Griffin site).
I recommend, unless the jack is in the glove box.
