So I bought a mono earbud (select the left earbud with ear loop) that takes the stereo input and mixes it to mono. I really like it because it leaves me with one ear still in the real world. This particular one has decent sound (I had buds that are better, but it's not bad).
But realistically one could simply use one bud of a regular earbud set. I don't think you really lose that much by listening to only one channel.
