2 types for day and night and they are BRILLIANT
I own both Sleep 2 and Engage Plus. Sleep 2 is getting nightly use, and with the revised soft feel, they are not making my ears numb, like the previous very plasticy Loop's were. Sleeping like a log next to a main road (the house, not me), plus not hearing animals or my shift working partner move about the room. Engage Plus have been great too, where my work has an old man cleaner drag a noisy scraping vacuum across a tiled floor for 2hrs (which should be 20mins) yet I can still talk with collegues. Most people don't even notice I have them in, and, although noise cancelling powered earbuds do a similar job, I rarely find the balance yet with Loop it's perfect. It's why I spent the massive money they want for them, and, these are my upgraded Loop's so I've been a customer since inception basically. Wouldn't buy any other earplug brands again, unless they kept getting more expensive in a Cost of Living Crisis.
