I've had the WF-1000XM4 ear buds a few weeks and have noticed no noise cancelling compared to previous model xm3. So today I went through the tip selection app and found that neither of the provided tips can be made air tight in my ears. I tried an onld song soft latex type tip not foam and that seals perfect and I have noise cancellinv in that ear now. Unfortunately I could only find one. Any one found an issue with the provided foam tips and found an alternative or a work around. Thanks in advance
