I want to be able to connect my headset (male aux connector) to the outputs of my phone and my electronic drums (female aux connectors)

Easy. You have a couple of options. One, the cheapest, is a 3.5 Y adatper. Plug both into it and run that to your speaker. The only problem with that is that you can only have one on at a time or you will hear both playing. The other option, more expensive but better results, is a 3.5 switch.

If it were me, I would go with the swtich. It is bi-directional, so you have more flexibility and can have 2 ins, 1 out or 2 outs, 1 in.

If you want to be able to listedn to both units simultaneously, you need a "Stereo Audio Mixes" - device with several inputs and one or more outputs.

I hadn't thought about that option. He may be wanting to play the electronic drums along with the MP3 player. Yeah, he would need a mixer for that. Something like this.
