I’m 5’1” with size 5 feet and short-average legs for my height. I ordered mine and received them a few days later. So glad this was an option, so I didn’t have to buy new headphones. This mic delivers superb low noise and a crisp evenness whether you use it as an instrument or vocal mic. Material is plastic. These fit wonderfully and theyre great to walk around in. very safe to do your full body training routine! It is thick and durable and really protects. I purchased this because of the hand pump. with he exception of the covers.
