My sos said he was able to walk to the other side of the room and the sound was still good. We own a boat and our shoes have to be able to get wet, all our other flip flops would begin to stink from getting wet. I fixed that by replacing the rubber round ear bud piece with a conical flanged one that works better. I hope I am never ready to go there. I still have moths flying around but apparently this is normal and the traps last 3 months so I have to be patient. Lovely looking sandals. The two that came with this product have already broken. They are exactly what they say they are. As mentioned by some other reviewers, to get the screwless finish you mount the rail over the brackets and then tighten two very small hex screws using the allen key provided. I had try everything from Amazon tips to there rave music explaining how to pair the buds.
