I realize that this is supposed to be comparable to 6 1/2 -7, but I do normally wear what I stated earlier. No one else will probably look that close, though. They can handle a very wide range of music really well. These are sized just slightly smaller than the unisex sizing. incredible! Overall very happy with this speaker. On the bright side it does charge very quickly. The reason Im on my third pair is I keep banging into things at work and eventually you just get unlucky. The case does not properly fit. Little on the large side I am a size 37(4)
