I love these. I spent ages searching Amazon for the right pair and saw a few good reviews for these. Fit me perfectly (I have a big head too) and easy to adjust. They don't pull or hurt my very long hair. No steaming up at all or leaking (after 2 hours swimming lengths). Fit snug to eyes without feeliing like they're pulling my eyeballs out. Recommended to all.
Love these. They are great value for money. Easy to use, and they have a brilliant battery saving feature which turns them off if you leave them on for too long (but not so short as it cuts off during my baking sessions!). I recommend these to anyone
