I stuck these to a poured concrete wall in the basement. The noise cancellation is also very impressive. These have no holes as is common in other models. It?s lukewarm when I pour it into the Navage. Mit Studien an der University of British Columbia in Vanouver, Kanada hat Nike wohl festgehalten, dass der Schuh Verletzungen vorbeugt. However, it came with the wrong hardware (nuts and bolts) and I had tocall Audio-Technica on the phone to get new hardware. My husband and I use our set and I even convinced my sister-in-law to get them and now her and her husband use them. Highly recommended and one of the best purchases I have made on Amazon. I was looking for some big sound and this guy delivers. Jetzt ist das Porto leider genau so hoch wie 2 Kopfhörer, doch die Firma VBP scheint mit diesem Model einen Exclusivvertrag mit Amazon abgeschlossen zu haben.
