Our adjustable cup/straight trumpet mutes are made with a carbon fiber barrel and 3D printed carbon fiber/nylon cone, end cap and cup. This mute is infinitely adjustable via moving the cup and also moving the corks up or down with the velcro strips. It also includes 3 sets of corks at different thicknesses.  It can also be used as a straight mute by removing the cup. It plays extremely open including in the low register. You can’t dent it and the flexible 3D printed carbon fiber/nylon cup is very durable. The best part is that it weighs only 90 grams (3.2 oz). Less than half the weight of aluminum mutes. Less stress, better musicality!
