I had Happy Ears recommended to me recently – they get good reviews, and they did work well.
Unfortunately owing to my frankly huge lugholes* I was worried that their Large would disappear into the ear canal. I could only get them out with tweezers, which isn’t really conducive to a good night’s sleep. I tried adding a tether but that just made them really uncomfortable.
So, if you have normal sized earholes, you’ll probably be fine and they’ll be very comfortable and block sound well – they do a ‘discovery pack’ so you can test the correct size. If you have large lugholes, look elsewhere.
*A combination of hereditarily large ears and having used various types of sound reducing earplugs for decades has meant I have lugholes akin to train tunnels.
