I purchased 20 of these for use with tour groups. They work very well as long as no one is more than about 50 feet away. If more than 50-70 feet away the transmission is lost. I like the small size. You must accept that the small size means that they do not have a replaceable battery. These have a built-in lithium battery which, upon full charge, will last many hours (15 hours?). However, you must charge these every few months and I once failed to charge just before use and discovered they were all dead. (I had charged them a few months earlier but the charge goes down week by week, so charge again just before use.) They take many hours to fully charge and the longer you own them the longer the charge time will take. Nevertheless, they are lightweight, take little room, and the voice clarity is very good. They cost much less than some systems and overall have performed well for me for two years. They come from China and will take longer than most Amazon items to arrive. (It took several weeks in my case but everything did arrive in time.) You can use any stereo ear buds or headsets with these that use a 3.5 mm plug.  Read Less
