Balance cable extension

So i recently bought Harmonicdyne Zeus and it comes with 4.4 pentaconn to L+R 3.5mm, unfortunately the cable length is small between my sitting area to my headphone amp.
My Q is what if i buy 3.5 mm female to 3.5 mm male for each L+R and connect them to my headphones basically extending the wire, does this complicates thing like any electrical problem or any danger to either amp or headphones
Can we do this?
