Not one. Not two. Three people asked me this question. No, I was not on a mini-bike, I was using my new headset, the H605. I was also asked "Are you talking through a tube?". None of these were the effect that I am looking for. Not only that, I guess my ears are too big for this too, as it is pretty painful to wear over time. Finally, I thought it looked pretty silly- which was the clincher. I had the H500 before this and unfortunately lost it. I guess I will be re-purchasing it as it was far beyond this one for sound quality and comfort on my XL ears.
