My only beef is that the instructions are printed on one side of a piece of paper. ??????They fit and look great. There were about 30 participants in the room and several on our conference bridge. And if the ?5 years of free refills? is what is enticing you, don?t bother. I spent $15. Hold tight on the IEM, for it is slippery. The bass button provides the speaker with real, deep bass that can be heard from far away. Literally cannot fit this on the stand. 3D wing design. Heres what I have found after using it a week on my fatbike.
