Used 6.35mm Phone to Speakon Adapter for 4 Pieces This listing is for four adapter bodies. There is no original packaging or other accessories. Photos 8 and 9 show phone plug cables for reference only. These are NOT included in this listing. Sound output has been confirmed. These are used items, so there may be minor scratches, etc. Also, there may be individual differences in the build quality from the time of purchase, so please consider this before purchasing. I used these to connect phone plug cables to speakers that only accept Speakon plugs to produce sound. They have the same size and design as regular Speakon connectors, making them convenient to use and carry. I did not feel that the plugs were loose when inserted into either the Speakon side or the phone jack side. The Speakon side locks securely.
