Regarding headphone extension cable

I have a pair of beyerdynamic dt 1770 that i really enjoy listening to music with but iv'e recently moved to a new apartment and now the chord can't reach so my question then is, what extension chord should i buy? Iv'e bought a cheap one for now, this one: wich is translates to roughly 5 pounds in cost. But should i invest in like.. this one?: Does it make a difference in sound quality? Right now i can maybe hear a difference but i dont know if it's an actual difference or if it's in my head. Any answer would be most helpful! // Victor

In most circumstances it won't make a difference but very badly built cables could impact the sound. I've used a Grado 15ft extension for many years and to my ears I cannot hear a difference vs the regular headphone cable alone.
