They are actually made for the human ear; one for right, one for left. The sound is good, comfortable to wear for several hours, lasts a long time with fairly heavy use. I bought a few more sets after the first one, fearing they would be discontinued. I bought the first set after the original ones stopped working in February 2016. I'm still using that first set.
