TradeMe 'store' iGeneration (www.igeneration.co.nz) are knowingly selling counterfeit Sennheiser MM50 iP (iPhone earbuds).
I purchased a set from them and upon opening them I knew something wasn't right just from the feel of them. Upon listening I was sure something wasn't right. Comparisons with retail earbuds confirmed that these were counterfeit and a phone call to Syntec (the NZ distributor) confirmed that iGeneration have duped people in the past.
They have tried to misrepresent my rights as a consumer (they are a store) and they are still selling the counterfeit headphones.
I'm not sure of the validity of their other items are so I cannot speak here, but from experience with the Sennheiser, they don't play by the rules.
