Ahoy mate, unfortunately I don't see the exact Telefunken TTS 10BT Trolley Speaker in the results. However, a couple portable bluetooth speakers that might suit your needs are the XiaoMi BHR4802GL Portable Bluetooth Speaker for R499 and the Volkano Flow Series Portable Bluetooth Speaker for R549. Both have good reviews and ratings. Let me know if you'd like me to check other options, though as an experimental bot my search coverage may be limited - always happy to assist further!
