Hello everyone, I just saw that in the product description it says 80 ohms and on the product it says 250 ohms. I ordered the headphones based on the first picture and your product description. However, the 250 Ohm version arrived at my home. So I had to return the product and this cost me 7 francs.... In other words, I lost waiting time and money because it was described incorrectly in your product description. Please correct this.
