I can hear with my conditioning no differences to the normal Bluetooth with SBM codec. Maybe my conditioning is also not so good, you could hear a difference there. That is why this review is purely subjetiv to see! Everyone should give it a try if it makes sense for oneself. At the moment I do not see why I should take an additional one at that very thick USB Adapter if the integrated Bluetooth already sufficient. But the product does what it is supposed to work and due to its construction even under Linux !!
