    I like the product but would be helpful if a little louder and have changeable lens from sun glasses to reading glasses and just clear lenses.

    I got these for my husband and he loved them. The only set back would be that he complained that he could not turn them up enough. After a month one of the lens fell out. They were awesome while they lasted.

    Glasses seem to be really good overall. The frames are bulky and tend to hurt a little around the arms near the ears. Sound is really good.
