Received yesterday these micro suede covered memory foam earpads for a pair of Sennheiser HD 4.50 Btnc headphones I bought off Ebay. They are the same over the ear size as a previous order of angled oval earpads in dark red. Which means they fit over the ears and not on them, which is a good thing! They do feel a little cooler after a 2 hour movie watch than the angled oval ones, which do get a little warm, but is still tolerable. Kind of wished they would come in more color's such as the dark red to match the angled oval pads! I'd use one for warmer weather and the other for cooler weather! Glad I found Brainwavz website to replace the original Sennheiser earpads as they fit on the ear, not over the ear. Better sound achieved with these earpads!
