About three years, so mine are the older ones. They came with three sets of cushions, but I had to use the largest ones. There are other buds that don’t have cushions large enough for my ears.
Bear in mind that, due to working the places I have, I am used to wearing “foamies”. Some people cannot stand the feeling of pressure that those give either, while others barely even notice. You can usually tell teh peopel who find them uncomfortable because, after a year or two working in a foundry or on an aircraft carrier, they are going deaf. If you can wear earplugs, you can wear the types of buds I like. If not, you will have to do without hte sound-isolating qualities they offer.
@SU_ZANN The iPad isn’t much more compact than a netbook, and definitely not pocket-sized, as the OP wanted. Also, while the number of apps available may favor Apple, the number of free apps favors Android by a considerable margin. And then there is the iTunes application, the only way to control an iDevice or transfer content from your computer. If you own a Mac, all is well. If you own a Windows PC (like most people) you will have issues, and if you own a Linux PC, forget it. By contrast, Android devices are easy to sync to and manage content on. Add in the better browsers (not stuck with Safari) and all, and you can see why I no longer use nor recommend Apple.
However, they do have good support.
