After the 10 Euro converter did not work at the Phillips TV (they hung up after some time), this 40 Euro Converter works now been 2 months without any problems. In the product description should mention, however, that this converter is also supplied with power supply. The power I still on a low-cost USB accessory cable (with 5.4mm barrel connector on the other side) produced for television and this would also do so repeatedly, since the converter by turning off the TV is thus off automatically. The one who has but no USB port on the TV can also use the included AC adapter. The converter is in the first place, therefore, become necessary as a Sonos Playbar was connected to the Phillips TV and the audio connection could be established only through digital optical (Toslink). The Phillips TV does have a digital audio output (looks like a normal black RCA), but this is just a digital coaxial (SPDIF also called and stands for Sony / Philips Digital Interface Format).
