Hello, the headband on my headphones is starting to crack. When I put them on, the band doesn't form a nice ark. It dips in where the cracks are, which luckily have gone all the way through. These headphones, Sentey Warps, have one cord on the left side, so I can't just take the speakers off and plop 'em on another headband. Should I try to fix the existing headband, or go through the trouble of carefully emptying the cords and threading them in another band?
