I'm going to be the odd ball and say I've been disappointed with my Howard Leights. Guess I was expecting too much but my take on these are they need more padding and compression. I've always used a quality pair of old fashion earmuffs and always they did a more than ample job of hearing protection.
Decided to get with the times and picked up a pair of Leights and like I already mentioned, I've been totally disappointed in them. Padding needs to be doubled and compression is weak. I'm constantly playing with them to find the perfect seal. When I do find it, it short lived. The slightest turn of my head breaks the seal between my head and the padding.
I mainly bought these because my job requires me to qualify twice a year at an indoor range. The range has a high tech air exchange system that quite loud. The range master shouts shooting instructions over a PA during the quals which can be hard to hear when you factor in the air exchange system, a decent set of old fashion earmuffs and ear plugs (double ear protection is mandatory.) My plan was to get the Leights and have them filter the blower motors so I could hear the RM. The Leights let so much sound in that I don't think I even need to turn on the mic on, I can just turn my head.
