My experience QC Ultra vs QC45 : r bose - Reddit My old QC 35 II also have a bit of white noise but much less intrusive then QC Ultra Then ca two weeks ago I bought QC SE (45) and my observations are the same as yours I don't see a justification to pay so much more for Ultra for so little difference and what's more the white noise is at the same level as QC35 II
Is there a reason for 2x 45s instead of a 90? : r Plumbing - Reddit Two 45’s are acceptable in the place of a long sweep 90 However there could be several reasons this happened Tho it’s not a big deal or problem Reply reply Tanner0614 • Two spare 45s is a lot better than a drive to lowes and back for the same result Reply reply cocodakinh90x • Reply reply [deleted] • Reply reply BR549J • Reply
