This is a very helpful and convenient electronic translator! I am excited to receive it. I have installed the App. I have tested it with my friends with Mandarin, English, Japanese, and French, their responses were very positive, they were all amazed how helpful and convenient it is. I tested its 3 modes: touch mode, free talk mode and speaker mode, all worked very well.

I also tried it to listen to music, and make/receive phone calls, the sound quality is pretty good too. The open-ear style is also comfortable to wear compared to in-ear style and won't fall.

This is a very useful tool for me, because I travel a lot around the world both for business and pleasure, I am going to Europe next month, so I will test it extensively in several foreign language environments and will update the review after my return.

In general, I like the earbuds very much, would highly recommend it to anyone who needs a little help in learning/using common foreign languages.

There are 8 offline languages, it's very useful when you are traveling in some foreign countries with poor cell phone signals/without WIFI services.
