Well logitech did pull that on me with my Z5500s. I had their flagship Z5300 (before the Z5500s) and told them I would not accept a lesser model. So I made them minus what I had paid for the Z5300 and paid the difference between the Z5500 from them. So I paid about $170.00 I think and got free shipping to my house :). If you aren't happy then maybe just accept the replacement and sell them and be done with UE. There are a lot more products out there that you may even prefer to UE.
