Excellent hooks. I have a Motobecane Champion road bike, and the installation was easy. 1/8" plug with threaded 1/4" adapter. Muy confortable! They’re super easy to put on and off and stay on while out and about. However, its a bike rack, so. Ive been wearing them to run 3-6 miles for 2 months now: 1-they are small and fit in my ears and stay put, 2-I have worn the left and the right together and singular and they have worked flawless (w/other pairs the right bud quit working and others I could not separate as advertised), 3-they have lasted on runs for several hours and FL heat/sweat, 4-there is a button on each bud which I prefer as the other buds touch didnt work with a sweaty fingers and/or kept shutting off 5-sound is noise cancelling, Don’t believe the hype. Theyre really like standing on an anti-fatigue mat all day. I prefer not to use the strap most of the time for easy on and off.
