Summary: Even though this is my third pair of these, I have never doubted Koss products. From my first purchase to now, these are still my favorite earbud earplugs. I wear them everywhere, and that's why I lost the first two. When I saw these on a display at Walmart, my first thought was, "I could listen to my music and mow the lawn now! And without buying $100 pair of over the ear phones!" But these were more than headphones, this was like listening to erotica in surround sound!
Summary: Delivered on every aspect identified in their description. I know Koss from their stereo headphones in the 70's and 80's and they have not lost their edge. I prefer these to the Sony soft earbuds I paid $20 for.
Summary: The bass on these headphones is AWESOME....I'm a rocker so AC/DC, Aerosmith, Stones, etc...sound GREAT...their noice cancelling capacity is so great...my phone rang right next to me and I didn't hear it..
Summary: Golly geez, Mr. Wilson, these are 'swell' (get it?). Well, they DO swell in order to fit into your ear. I highly recommend you do NOT order these 'Site-to-Store', especially to Walmart, as mine arrived with the first set of earplug sheaths crushed (KOSS product packaging is fine for peg-board displays, but not shipping in a poly bag, anyway). Overall, I give these about a 7 out of 10...for the price, now, it's different--9 out of 10.
