now the shoes are unavailable to purchase. I would definitely recommend to anyone that works in the food industry and needs good,no slip shoes. They are more comfortable than the a50s and you do not have to worry about a buzzing noise that may occur. The strap hangers are great for hanging extension cords. I switched on SH mode and could instantly hear footsteps and the placing of barricades to my right. Only the right one got connected to my device but it became disconnected in a few minutes and had a lot of interference. It also has one of the clearest sounding speakers Ive heard in a portable unit. Im happy to report that it "just works" for everything except Linux. It was a really good starter kit. Clear sound across the shop and two of these can be paired together if you would need more power.
