The headset is comfortable and adjustable and fits my (smallish) head well. I love the colors and they are very comfortable. I have four pairs now, bought over four years. High chances of being cracked, once taken out, it would never fit as they were factory install. El sonido está bien, y nada más. I maintain a relatively small and mobile wood shop and use various slip fittings to attach this hose to my 4" ducts on both my jointer and planer. I am not able courier the item back due to halt of courier service in my area. The arch support was off and the fact they have no base in the shoe makes these terribly uncomfortable. Wish I had ordered 39. And my goodness it?s so conveniently small, ideal for travel.
