I have 15s and I can't use them if I really want to hear my rig properly. If I wear them I can hear guitar and drums very well but bass is somehow tamed and I am losing high end. On top of that, one plug is much longer than other and it feels like it blocks my ear canal much better, being also less comfortable. Really mixed feelings about this product.

I would go back to the audiologist who made the moulds and get them to make it right on the fitting.
