Se escuchan muy bien. Very helpful long cord. I have 1500 pounds of free weights throughout my basement so I bought this stand so I am not carrying them from one end to the other. The sound works good, the fan is nice and cool, and it’s light is a cool white light. I’m a size 8. Transaction with seller was very positive, and I got a refund immediately when I wanted to return the shoes I got because they were too big. Unfortunate that I have to return this item cause the sound quality is pretty damn awesome but it fits terribly, for me personally that is. B&O has historically had problems with new wireless products, in my experience. After I washed/dried it shrunk and the length is right above the knee. The 1am2s can work well with cell phones and are loud (16ohm) but these z7m2 are quiet on cell phones due to needing more power to drive them (56ohms).
