Need help with best way to reduce noise at night, without earplugs!

Hey everyone,

I know this isn't strictly a HI-FI-related question, but I don't really know where else to ask!

I usually use earplugs to increase my quality of sleep, but I think they are starting to damage my ears, and don't want it to become a permanent problem. As a result, I've started to look at purchasing a pair of noise cancelling headphones to take the earplugs' place, but wondered if anyone here has had any experience of them.

I've narrowed my search down to the Sennheiser HD 598s and the Bose QuietComfort 25s or 35s.

Any advice would be much-appreciated, as I've only read mixed review about the noise-cancelling properties of these headphones etc.

Cheers!
