MacBook – How to use two USB devices with the new USB-C MacBooks

I recently was provided with the latest MacBook model, for which Apple decided to switch from a number of ports to just one, USB-C port and a headphone jack. The only two accessories that I use on a regular basis, a mouse and a headset, both require a USB port which was not a problem on the old models. One can purchase an adapter to fix this problem, either a USB-C to USB or a USB-C to HDMI+USB+USB-C. Here the problem arises that there is only a single USB-C port, and these adapters only provide one USB port. Is there or will there be a way for me to have both my accessories function? This doesn't seem like an abnormal problem to have, but I can't find very much information on the topic.
