I use a Nobsound amplifier to connect my TV to two high quality black and white speakers. I connected the TV's headphone output to the amp and encountered a serious hum and noise issue. Adding a low impedance load in parallel with the input completely solved the problem. I did this using an audio adapter with two 3.5mm jacks as inputs and one 3.5mm output. I connected a TV to one input and used an IFI Ear Buddy headphone adapter as a low impedance load on the other input. The output of the adapter was connected directly to the Nobsound amplifier. Now we have quality sound for TV. If I want, I can turn off the TV and use the speakers as bluetooth speakers, which works well too.
