So received by adapter rings in the post today and was quite excited. Then I tried them out and realised they were pretty awful. The earphones keep falling out of the rings and that's just while I'm sitting at my desk, I'd hate to think how bad they'd be if I was leaping about the stage. Also, because they don't go deep enough into my Elacin ear plugs, it takes away from the quality of the sound from the earphones. Avoid, avoid, avoid.
