Keep in mind that these ear muffs were also tested with the Peltor Securefit 400 shooting glasses which have very nice flat temples/arms which didnt cause any sound leakage. She loved the slippers and wore them the whole time. The battery doesnt last long and the instructions on what to use which pieces for is pretty vague. Also true to size. I like these shoeboxes. I cant put it together the box was damaged on the corner and I lost parts and screws . good to workout in I love it! I own a Topeak seat bag that Ive had for many, many, many years that is still going strong. The only thing I have not reviewed is the battery life but people I tell you, the charging station box that ot came with have a full charge and it only means that it should have a good battery life. Its exactly the right size.
