I lost my original set at a gig and so this set is a replacement. I love the voice straw and bring it with me to show for a quick reset.
These sizes are great in comparison to the average metal drinking straw. The cups work well, and they do work pretty well over facial hair. Highly recommend - I like to start with this before moving on to other more traditional warm ups. Amazing for cool down post gig.
Love the big kahoona for gentle warm up and using the 3.5mm for general phonation. The cup works well even on its own without a straw. Couldn’t get the combo to work with good air flow (using two 1.5mm to make a 3mm) 2.5mm and smaller was just too much resistance with or without water. Wish there were an option to build a set; the traditional 3mm silver straw on their own, with one or two other sizes.
