On the left earcup there?s a singular button responsible for the ANC control. I had to wait a month to use this because of all the fires in California made it unusable until all the ash was done falling. As beautiful as prior reviews stated The first thing I notice is the vendors box. Having it on low volume helps the battery last longer I think. I sent back to the retailer, Tower, who informed me that they would not replace. The speaker has performed flawlessly on all of them. so I have ADHD and didnt realize that this was a band for apple. If your child has a wider foot you definitely want to order a wide size. The cord is long enough for what I need and I was pleasantly surprised to see how sturdily the product is made.
