I had a spring squeak for the first two days of use on brand-new bindings. Once I readjusted the cable tension after initial break-in, they're pretty quiet -- I think. We've had nothing but noisy conditions so far, so if there is still a squeak, it's faint.
Get a set. You won't regret.
That saying should be trademarked.
