I thought I was listening to stereo theater sound, surround sound, THX, Dolby Digital, whatever you call it. I have no complaints about this product I just started a new job and decided to get a waist trainer to wear while I work and its perfect its very breathable and comfortable Im really glad that I bought it. And that is with a 4 year old in the house too. If it bothers me a lot later, a simple fix will be to use some small zip-ties to make the attachment more secure. They are very comfortable, and fit well. Ill be looking for a different set personally. The keys were wobbly and the stabilizers (metal bars under space bar, shift, backspace etc) kept popping out. I can still hear my music clearly even it is kind of noisy around me. Very much worth the price! My opinion doesnt really speak to their role selling and shipping the shoes, but if someone asks my opinion, and then pesters me, well then I will post something about the product.
