My girlfriend uses Loop every night (the dog and I both snore like fuck) and she likes them. I've used them on occasion as well and they're pretty comfortable. I mostly sleep on my back but am on my side probably 25% of the time. I've not tried Bollsen to compare!
Earplugs suitable for sleeping in. I'm a side-sleeper.
Preferably reusable, <£30.
Are my options Bollsen or Loop?
