Don't know how it is assumed to easily put on these replacement earpads, but too myself and with help of wife's hands to finally get both pads to fit inside of small gap around the Sennheiser HD 4.50 Btnc headphones. Original earpads are not (fit over the ear), but on the ear from Sennheiser! Caused problems with hearing full audio sound. Possibly if you have small ears, the originals will be fine! I don't consider my ears large, I'd say average in size. They pull off easily enough. But putting on a pair of these Brainwavz ovals was an hour pain in the butt! The dark red looks more a maroon color though. That being said, the replacement oval muffs are larger, fit over the ears with no problems, are snug enough to block out the ambient sound of a box fan running on low! Sleep with a fan running all year long! I'm hard of hearing in both ears! But these larger muffs made the Sennheiser HD 4.50 Btnc come alive! Actually have to lower the sound from these larger, better fitting muffs! I also ordered an angled oval pair of muffs with the Velour on them! Watched a 2 hour movie and muffs were somewhat warm after sitting against head and jaw afterwards. Not hot, but warm. The dark red does look nice against the mostly black Sennheiser's. But in my opinion, kinda has a maroon look to them! Very glad to have found the Brainwavz site! Now I need a pair of Skullcandy Crusher ANC XT for my old time rock and instrumental music and order some Brainwavz for them!
