It is true that Bluetooth speakers commonly do degrade the audio quality to a varying degree. But it doesn’t necessarily have to. It is primarily up to the manufacturer to use the Bluetooth in a way such that it diminishes the audio quality. You could always consider different codecs to overcome this. This way, Bluetooth will not have a significant impact on sound quality. There you got the answer and the solution as well. Overall, if you have purchased the speakers after exercising all the cautions, you will have them with you for a long time without any regrets.
