<p><span style="font-size: 10.5pt; line-height: 107%; font-family: Arial, sans-serif;">And if you want to talk to the person sitting next to you, that's no problem either. The convenient TalkThrough function enables you to conduct a conversation without removing the headphones. At the push of a button, miniature microphones mounted on the outside of the headphones pick up the surrounding sounds while an electronic circuit filters out the voice of the person speaking to you and plays it clearly through the headphones.</span></p>
