Extra Carry Case Loop Switch™ 2

Great earplugs!

It's my second pair of loop earplugs. Had to purchase the second pair as I lost the first pair due to my own clumsiness. I can genuinely tell a difference between the different "switch" options, it's great for working in a busy office space and keeping your concentration, commuting in public transport and taking the sharp edge of noise off in any other surrounding

Excellent in every way !
