They sound great, shipped fast, and even light up and have a radio! I sent this back because i needed smaller but what I can say is it was very sturdy, defo a heavy duty rail, easy assembly, I stupidly ordered a different one to replace and wish Id stuck to the amazon one,good value for money Once I use it (if I remember), Ill post an update. But an attractive shoe. My work requires I travel extensively all over the world. Sturdy base keeps everything in place and the wire grooves on the under side help prevent cord tangle. I adjusted the headset volume to its highest level, but no joy -- still the same dim and distant presence. Decent secure fit. Bought this little gem after losing my keys in a classroom while working on campus, alone, during a planning day 🙃😅 I never lost my keys again. I will say that building it was kind of a pain, but overall it’s very sturdy and pretty small so it can fit in most places.
