My third pair. I purchased in 6. Quality is very good and battery life is very good definitely recommend this product Overall I am very happy with this and would certainly buy another from this same manufacturer. This wasnt an expensive purchase, but I think I have finally learned my lesson and will not buy clothes from Amazon again, its just not worth the hassle when the clothes dont fit right/feel comfortable. Based on the reputation of Bang & Olufsen, I thought these stood a good chance to be a decent replacement for the QC-20s. Only negatives are that the instructions are truly terrible. I bought them for my 7 year old grandson to wear Christmas morning after watching a favorite Christmas show where a boy has to wear pink bunny pajamas! They are expensive in my opinion but worth every penny. My only complaint with it is that the base is too small so the rack can tip over easily.
