You just hold the hook up to the wall where you want it, and start screwing in the anchor directly in the hole on the bracket. Some reviews said to order a size or size & a half up from your normal shoe size. No negatives with the wireless sensor, no discernible delay. One drawback is this device is heavy. He first tried them on wearing socks in case they didnt fit and had to be returned, and could not get his foot in at all. ANC and transparency modes sound solid and are more than effective at canceling out noise or letting it in. and then all of a sudden you understand why they give a skimpy little worthless gasket in the first place because if you actually tighten this down all the way the bracket will surely bend. Now, I must say, and Im not speaking for everyone but myself. That being said, I probably wouldnt know if it was the Emeet or if it was the voice to text app or the internet connectivity if it did happen. I’m going to torture the children next door with some excellent death metal!
