Comments about Eartec TD902 2-Person Wireless Communication System with Ultra Dual Headsets:
I was using this product while horseback riding with friends. This product is billed as multi-user. It is, in fact, multi-user for maybe instructional use where several students are listening to ONE instructor. However, not a good product for several people to be able to converse to one another. It only works with certain headphones, and doesn't stay charged for very long. I have only used them twice, and they are more trouble than they are worth. I can't wait to sell them! Clear sound when they work! ...When they work being the operative word!!!
