"I thought they might be a bit average because they are so cheap, but I was wrong - sound absorbtion is very good and, though a little heavy, they are comfortable too. I used them whilst breaking out several concrete posts. Bought my daughter a pair too - she helped me - and we had to take them off to hear each other!"
"Great looking & performing set of ear defenders. Their ability to cut out noise is very impressive & they're comfortable with it, allowing you to wear them for long periods. My only issue is with the adjusters, which are a bit flimsy. OK for DIY and contractors - not sure they'd last very long on a busy building site."
