Im always using my Earbuds when im working. I use alot of different maskines, but one machine my Earbuds cant handle and gets a “Screeming” loud sound, And that machine is a grasstrimmer. As soon as i starts trimming, is screeming and music disapears. If i turn of ANC and then the screeming disapears. Why is that? Already tried to send to my reseller and used my warranty. they sent a new one and still same problem.
