I think you have to buy them in a store to be sure. I compared with my Walker’s Razor and could say they isolate the noise better or almost the same. HOLY COW! I have a much older Bose soundlink mini Bluetooth speaker that is still running strong after many years. Maybe some people feels like it massages the foot? Not me, they are very uncomfortable. Good stuff for the kitchen. Like others have said, the bolts could be an 1/8” longer. I will say that due to the very wide beam with this light, you will be very visible to drivers. I love these because they are directly from Germany and just wished they had many more colors and designs. These do not fit what it says it fits.
