Subject from China, count 10j of delivery (announced and respected). Tested with android smartphone on Bose SoundDock Portable, works very well. By cons I have not got it to work with my laptop (apparently connected object but can not transmit audio streams in the state). This is indeed not specified in the announcement, but it appears on the packaging of the product, it must be possible. The problem seems to come from Windows and not of the adapter, so I will withdraw no stars for this worries.
