Owner Reviews, Ratings, Comments and Criticism
I really wanted to like these, but after they (finally) arrived, they were not exactly as described.
The behind the neck "strap" is really just a connector for the two hearing protectors. It will not stay on your head unless you use the Over the Head Strap, which is not in the product description or picture as of March 2010. Having to use an over the head strap defeats the purpose of getting ear protectors that are behind the neck instead of over the head. The one and only mention of the over the head strap is in the directions for putting on the ear protectors where it tells you to secure the velcro the strap over your head. If this had been mentioned or even pictured on the product page I wouldn't have tried these.
Additionally, the ear protectors interfered with using safety glasses--wouldn't let them sit normally on my face so my eyes weren't completely protected. This doesn't happen with normal over the head protectors (which I'll be ordering to replace these).
I'd like to give these a good review, but they aren't usable for me. They could work for someone who just needs them for studying--if they don't mind a dual behind the neck and over the head system. They do not fit like behind the neck earphones that you can use with an mp3 player or an iPod.
