Each ear bud has an embedded microphone to enable 360 (degree) binaural recording, so you can precisely capture everything you hear around you. Ideal for long-distance recording and playback in large lecture halls, conference rooms, or noisy environments.High quality, anodized aluminum design helps isolate external noises for crisp, clear recording. Ultra compact size for convenient storing in an accessory pouch or pocket for easy access. Earbuds work with all Echo and Sky WiFi smartpens.

Livescribe designed the built-in micro-phone in the smartpen for monaural recordings in smaller recording environments, such as a conference room. When recording in larger spaces, we recommend using 3-D recording earbuds, which contains a microphone in each earbud. The dual microphones enable binaural recordings, which accurately recreate the spatial audio environment.

Binaural recording is a special type of stereo recording that uses two microphones, one placed in each ear. This type of recording provides the most accurate spatial sound quality because the microphones effectively mimic your ears - when you play a binaural recording back, it sounds like you are actually in the location where you recorded.

Once you record audio, you can play back the binaural effect using stereo earphones. You can also play back the binaural effect as a regular stereo recording over any type of headphones or speakers.

Tip: Record binaural audio with the earbuds in your ears or around your neck. Make sure the “L” earbud is in your left ear and the “R” earbud is in your right ear.

Note: Keep the earbuds about 6-8 inches apart to mimic the position of your ears.
