Upon turning it on, the speaker is making a slight static sound and has not stopped. Purchased these for a bar we were building out of an old entertainment unit! Will find a different brand for our next purchase. The plus here is for those guys who want smart looking sandals but dont have beautiful toes or toenails! The only sandal or even tennis shose that helped me with sudden Plantar Fasciitis . Unfortunately they shed. I gave it 5 stars because it?s a great product, it just didn?t work for what we needed! The first one wore out after a few years and the volume buttons stopped working. We use this for trap shooting. The tiny sag is easily remedied by adjusting the angle of the vertical and the location of the foot.
