I was long looking for such an adapter, since the neurons have JVC boombox models had no line-in more, except an iPod dock. A simpler adapter from Amazon was not working. In this, however, a (supposed) iPod is detected and the line-in works fine. The Comes complete with Micro-USB works; handy if you z. B. uses his mobile phone as a source, as they almost all have now a Micro-USB.
The adapter itself looks relatively stable and high quality, is well made. The cables are a little short, but it remains however manageable. Especially as the cable can indeed be extended.
5 stars because it works and it could not be better, in my view.
