Hi. Has anyone had a chance to try these out yet? http://en-uk.sennheiser.com/pxc-480?v4r

I have also been looking for a good open bluetooth stereo headset. I want to use it for cycling and in the car, so a closed one would simply be too dangerous.   For some reason, the MM 100 remains the only Sennheiser one without apt-X. I asked Sennheiser customer support yesterday whether...

Maybe the Sennheiser MM 500-x? http://en-de.sennheiser.com/mm-500-x

Hi, I also have a large head and can confirm that the HD4x8s are quite comfortable to wear. They are light, don't exert too much pressure on the sides of your head (so glasses are not a big problem) and they don't make you sweat a lot, even if you wear them for longer periods of time. They are...

PX200W might be the previous (and definitely inferior) model in white. If you do decide to go for the 200-II make sure you get PX200-II and NOT the old PX200, even if they are cheaper.   The PX100 are also foldable and sound fairly nice, but they are open and allow a lot of sound to leak in...

Hi,   If you don't want IEMs and need your headphones to be foldable, maybe the Sennheiser PX 200-II are worth a try?   edit: (( Ignore this, someone has already suggested them ))
