Smart tech from StepLabs compares the sound from twin built-in mics to tell the difference between your voice and background noise, and filter it out. The results your voice sounds clear and natural on the other end. A comfortable, sound-isolating in-ear fit makes incoming conversation easier on your end, as well. Great sound is only half the story. We ve added human voice confirmations to make SmartTalk easy to set up and use. No more beeps and bleeps; instead a pleasant, human voice confirms every operation.
