Also works well for my husband who is 220 pounds I was looking for an upgrade to my Neewer NW-700 I purchased on Amazon too. I included a picture of my glasses with the muff so you can see how it pushes in. I like the quality of this product. Excellent product great value for the price It goes more than loud enough, has clear, crisp sound and is tiny. Its quite comparble to the HD-25 in term of sound signature, maybe a little more room. I bought this to keep the fob looking somewhat mint as I still carry other keys and assorted items in my pocket that tend to scratch and wear out the key fobs for my cats. Love love LOVE! Our spices are much better organized now.
