    Really decent set

    My current pair is starting to wear out after a few years, will have to get a new one. Not sure what they difference between the MX and CX is though.


    I've owned this pair for a few years now and that's amazing in itself. I spent many years buying ear buds every 6 months. If you have an active lifestyle and a heavy user (commute by bike, jogging, listening at work) then you want something that lasts. To go multiple years on these is worth the cost.


    Once the slip on ear covers come off they have a tendency to always come off. I have lost and found them on many an occasion.


    They work well with my android phone while on a bike, a run, or just walking about.


    I would recommend this to a friend.

    Great Evolution, Bluetooth ones please...?

    Bluetooth these babies, please, not just the CX range.... Come on :)


    Previous review saying lack of bass?? What are they listening to? I've had the last 4 generations of the MX range & found all of them to be great. Once you get used to the silicone ear pieces, these sound booming & they are lasting well too.


    Not a fan of on-the-cable controls. The slidey up-into-the-ear holders have loosened a little bit & the cable clip has gone rusty


    I wear mine all the time, that they are not isolating means you still feel aware of your surroundings on buses & on the street. Comfortable for wearing when running too

    It took me some time to get it right. Once I did, WOW !!

    This set is perfect in any respect. I will just comment about the sound. Well, out of the box, I put them on, connected my Android, and got disappointed by the sound. I tried with my lap top, and got the same impression. I was sure that I've thrown away money... Then on evening I sat and played with the fit a little. I swayed the silicon buds up and then down, keeping close attention to the effect of this positioning on sound. And finally voi-la! As I turned those buds downwards, and rested the ear set slightly at an angle, suddenly all the Sennhieser goodness came to be. The sound suddenly became crisp, bass was deep, and overall music became more airy. Bottom line, you have to experiment to get the most out of it, and once you reach the sweetest position that fits your ears, you'd love them, I'm sure.


    Very well built. Best materials. Great durability. Perfectly fit my ears. Not fatiguing at all even after long hours. Android operation is perfect. Sennhieser sound quality.


    One (well, I) must get to know them a little.


    Telephone calls, gym and workout.


    I would recommend this to a friend.
