Way better quality than any other fisherman sandal we?ve gotten him, and cute pattern (we got the beach ball pair). Son las originales y de excelente calidad. The hooks are sturdy and show no signs of strain from all the weight I?ve put on them. Summary:As mentioned, tested with others. Sssh! But I am STILL giving this device a 5 star rating. The molded insole is great for support. While listening to the second song on my phone, the speaker belched out some "digital distortion" at several points ("grinding", "gnashing"). There is no background noise pickup (though there is little background noise in my environment) and the overall tone is rich and clear. Sort of like an uncomfortable swimsuit.
