?Beyerpeak?, der die Frequenzen zwischen 6k und 8k zum Zischeln bringt, im Hochtonbereich. The quality of the stand is very nice, solid, and not likely to fall over without bumping into it. These have to be FAKE! (Review by husband of account holder). The case itself is very thick and sturdy and serves its purpose in terms of being protective. Update: I reordered and received 2 9. The product itself is exactly as described. Low quality broke within first 2 weeks I can?t speak to the durability with travel/commute bc of the SIP covid times. Not only that the anc that they?re going for isn?t even as good as the anc on the beats studio 3s!
