An old portable radio with an auxiliary headphone jack has a great sound. But there is no Bluetooth, USB or other connections. My phone only has USB-C, no headphone jack. This allows me to play sound on my phone through a good speaker system. I use it a lot in the shop so I need a 4ft cord that is flexible and strong. Meets the requirements and works great. Update: I bought a second one to use with my car audio system and it works great too.
