Below are excerpts from the review:
Although initially I thought that the ddHIFI – TC28CPro would only allow simultaneous charging of the source device and listening to music, it quickly turned out that these are not the only functions offered by this adapter. First of all, the complete separation of power and data translates into a cleaner and more stable sound. At the same time, the ddHIFI – TC28CPro is a wonderfully made and very functional addition for all lovers of smartphone audio. In my opinion, considering the price of less than 30 USD, we can enjoy a really great convenience.
