Very comfortable and flexible as compared to hard plastic ear pieces.Comfortable on my ear. Could be a little more snug. I like the idea I don’t have to take it off my Bluetooth to reposition it to use on other ear, just a slight twist. Worth the money.Almost to flexableGreat deal doesn't fit Samsung BluetoothWorn for a couple of weeks and my only complaint is the loose fit.They are too flimsy they will fall off your ear very easily they barely even hold the air piece close to your ear so you can hear what's going onPerfect fit for my Link Dream earpiece.. The ear hooks are soft and flexible and do not irritate the back of the ear. So excited to finally find suitable soft silicon hooks that swivel so you can place on right or left side. Reasonable price is a plus also.I've bought a lot of these of various brands. These are the most solid, best fitting and most well made of any I've tried. The swivel end is nice.There isn't much to say about a little hook of soft plastic, except that these are the nicest I've found.
