Question about Shokz OpenSwim

According to the manufacturer Shokz (https://shokz.com/products/openswim), this product has been renamed from "Shokz Xtrainerz" to "Shokz OpenSwim". The same product is listed twice on Galaxus, both as Xtrainerz and OpenSwim. However, the Xtrainerz currently costs CHF 247.- and the OpenSwim CHF 163. Since the product descriptions are different (sometimes incomplete), it is not immediately recognisable that it is the same product, not even through their "comparison function". I find this practice unfair to the buyers and would like to ask you to fix or declare this. Thank you very much
