This review is from: Sennheiser MM50iP Stereo Headset with integrated microphone - tailormade for the iPhone - Black (Electronics)
Unfortunately, whilst these headphones look just the ticket, they are fundamentally flawed and don't work properly with either the iPhone or the MacBook Pro!!! I have had a replacement iPhone so am pretty confident that it's not the jack itself. The issue - only sound from the right earbud is normally available. It is possible, by rotating the plug in the jack or loading it to get the other one going but usually this only works for a few seconds. I am really surprised that Sennheiser (or Apple?!) got this key detail so badly wrong.
Another point that isn't made clear in the blurb on this product that you could do with knowing in advance is that, unlike the std iPhone earphones, there is no volume control on the remote - you have to get the iPhone out of your pocket/rucksack if you want to change the volume. Again, another pretty key feature to a set of "tailormade for the iPhone" earhones wouldn't you think?!
Finally, if you do go for them, you might find, as I did, that the replacement buds are not paired in different sizes!! I've got 3 large, 2 medium and 1 small - handy, not!!
