Sorrry, it may fit a jumbo bottle but I wouldnt trust the strength of the arms to anything more than standard sizing. No worries about theft! They are the perfect size, and they are solid metal so they are sturdy. The instructions were daunting when I first looked at main picture. I do prefer listening via wired using my Dragonfly Black and listening to lossless or MQA files via Tidal. This is a minor detail that could become important if you need this information for the warranty or other reference. These are great and comfortable sandals. They do not hold the hook securely to the wall. One small comment of caution. To my surprise there were no instructions, just a useless piece of paper saying it had been quality checked.
