I work a minimum of 8 hours a day on my feet in a fast paced restaurant. Mids and highs are crystal clear, bass is clean and punchy but not boomy at the extreme low end. I would highly recommend them to anyone looking for a great slipper. The one thing I wished were better is the lock mount. I am sure the soles will stay put to which is a big problem with the more expensive ones. I am working from home and use a headset for phone calls. Warm jacket, has room for layers underneath. I gave it 5 stars but this item deserves more. I think this is a good investment without a doubt ! I have worn these for a few weeks now every day and there is no sign of wear, ripping or damage, though Im not the type to wear slippers to Walmart, only indoors.
