All Bluetooth earpieces are not created equal. Griffin introduces the SmartTalk earpiece. SmartTalk uses a dual microphone design and MyVoiceTM acoustics from StepLabs, to eliminate noise by comparing wave shape and time of arrival between the two microphones. This gives SmartTalk an amazing ability to filter out and ignore wind and external noises. The result is: your voice sounds clear and natural on the other end. A comfortable, sound-isolating in-ear fit makes the conversation easier on your end, as well.
