【Cash on Delivery (COD) Accepted】Items can be combined for shipping. Moldex Noise Reduction Earmuffs Model#Z2 Color: Black Over-ear style Adjustable length Recommended for children and those with smaller heads. I tried these on for only one day and rode the train and went to a festival. Almost completely blocks out quiet sounds Can still hear announcements Festival music becomes a pleasant background Engine noise and cicada sounds, which are usually unpleasant, were bearable while wearing these. The soundproofing performance is quite good. I am selling these because they were a bit tight for me, as my head circumference is larger than the average woman's. (Will be disinfected with alcohol before shipping.)
