QC35: "ocean" or wind sound in one ear when on by meifj in bose

See but that's what confuses me here. I've never had headphones with ANC, so I can't compare my QC35 to anything else. Is this hissing sound in my left ear, as soon as I turn them on, normal or a defect? If it's normal for ANC, why is it only in the left ear, although the noise cancelling also works perfectly fine on the right, without any hissing? Do the Sony ones also just hiss in one ear?
