Disappointing but Functional
I've been using these regularly for about a month now, and they do work, but this set up does constantly seem to sound empty well before it actually is. On top of that, the sets I received have a face mask instead of the specified tees that I specifically wanted. The mask is causing break-outs on my chin even though I keep it clean. It's a good price for some back-up supplies, but I honestly would not order this set again.
