Maybe someone has a similar application field, then help him / her the following information: the Lindy Audio Converter runs at 5V, so that you can provide him with power via USB! need unlike other converters, the 9V or more. With a cheap adapter (2.47 incl. Shipping) here on Amazon ("Adapter USB to 5.4mm DC Plug" from DELOCK) you can let the included AC adapter safely in the packaging. I use the especially with my Macbook, which I go from different coax sources in the optical input. At home it is then usually the other way around, and optical out via the converter in the monitor speakers. In this respect also very convenient that you can switch the direction and I do not need 2 parts.
Incidentally, the power supply via USB also works on the TV (if it because a USB port has). So you do not need there still an extra power supply slot and the Lindy pulling (or receives) only electricity when it is needed that is when the TV is on.
Otherwise, the build quality is convincing and pleasantly small size (5 x 5 x 2.4 cm).
For me, these were the reasons to resort to more expensive product. Who only once connecting the converter and verräumt in the closet, converted in only one direction and him / her an additional power supply in the wall outlet does not matter, for it will probably do the cheaper competition.
