I?d say that you should check what recording material you?re listening to. Ill use it just not every day. So far they work great. This purchase is huge winner for me. my granddaughter loved them! Once assembled it seemed sturdy moving 225lbs around on it for presses and squats. I was worried I would need gel insoles as insulation in them because we walk on a very rocky path. Last month I had to take a call in a network room where the speaker was literally placed 12" away from a Cisco 3750 switch, and the conference participants couldnt hear the background fan noise from the switch. It worked perfect but for only a week. Dont ask why (ha-ha).
