Works with Sennheiser wireless base,
Verified Purchase(What is this?)
This review is from: Connected Essentials CES20 Wireless Speakers (Electronics)
I found these to be a bit hissy and crackly when used at the far end of the house. I was pleasantly surprised though when they picked up the signal from my Sennheiser wireless headphones base. This gave them a much better sound from the stronger signal. So there isn't a lot wrong with the speakers, it is just the base that is a bit weak.
They 'eat' batteries as well so just use the power supplies.
