    Best headphones I've ever used

    I listen to audiobooks everyday while driving, bike riding and while falling asleep. These headphones have lasted and held up brilliantly. They cut out the background noise of the dirt roads I travel and are compact enough to let me lie down while wearing them. I am really rough on my headphones and other cheaper brands have lasted less than a week, I have had these for over 6 months and they are almost like new. The only wear is on the casing of the jack which is starting to split from the amount if times I grab it and roughly yank it out (a touch of electrical tape will fix this). I also purchased the packet of replacement rubber buds and by replacing them each two months the headphone have retained their comfortable, noise canceling fit.

    The Best headphones!

    These headphones are so good. I use them at Uni, so the cord length is perfect when at the computer and my laptop, it doesn't get in the way. They are also perfect for running, they don't fall out and at the gym on the treadmill I can't hear any of the noise and the other music that's playing and again the cord length is good for that as well. They deliver on everything - noise cancelling, comfort, fit etc. They really mean, bass and noise cancelling - I have had people talk to me, who are sitting right next me and I can't hear them and they can't hear my music - perfect for the library. I've had other cheaper headphones that say noise cancelling and bass but nothing like these headphones. The perfect headphones! I have had other Sennheiser headphones and they lasted a couple of years and i'm really rough on my headphones, I fall asleep with them in and wake up and they've been rolled up at the end of the bed, and they still worked the next day, I've done that with other headphones and they haven't lasted two days after that, so I really trust that these will last.

    Sennheiser MM30I

    I would recommend you buy this if you have the money and not look anywhere else.


    Has excellent bass. Works with all my devices. No change to the music from the recording


    The price. Got a cheaper Sony one and they sound next to the same but less bass.


    Music with lots of bass. Good with voices.


    I would recommend this to a friend.
