I purchased this around last fall. It's new and unopened. Thank you. Brand: TwoBow Color: Black Headphone Type: In-Ear Model Name: TwoBow Connectivity: Wireless About this product: With microphone [Product Description] 1. Conveying feelings: Communication including gestures, facial expressions, and body language becomes possible. Consider the other person's words, "It's fine." Is their expression cheerful? Or do they seem reluctant? With in-ear voice translation, you can converse while looking at the other person's eyes, allowing you to understand nuances that are not conveyed by words alone. 2. "Conversations while doing": Giving directions while pointing at a map. Conversing while looking at documents. Because it's an in-ear type, it won't restrict your actions. The microphone is built into the earphones, allowing for hands-free conversations.
