Sorry to hear that Re-Timer is a little large. We did design Re-Timer to fit the majority of human head size with research found from median measurements around the world. However that does mean there will be persons, like your self it seems, outside these size limits, where Re-Timer will not fit quite right. There isn't much we can offer to make it smaller for you, but we have has good success with other customers doing to following. 1. Re-Timer can be worn over the top of reading glasses, so we have has customers attach Re-Timer to their reading glasses that do fit their face to help keep them on. 2. Attaching a string or/ glasses neck string to the arms and tightening it at the back of your head. To assist keeping Re-Timer more secure on your head can help also. I hope these suggestions help.
