Summary: Be careful with these. The plug buckled as i pushed it into my ipad and then snapped in two as I pulled it out, leaving half in the headphone socket. I was using very little force, and now I have a damaged ipad and useless earphones.
Summary: Whilst they do the noise cancelling part somewhat adequately, the sound is pretty awful for doing anything other than taking calls. Yes there is bass but the top end is terrible: tinny, distorted, unclear. I realise these are competitively priced but I expected something more from Sennheiser.
Summary: Hopefully it's just me, but these earphones broke within the first few days of use. Unfortunately (I think) it was my own doing..... I think? I'd placed my tablet with earphones on the bed, then a t-shirt on the top...

My 2 year old phones sound much better as per the sennheiser I've come to value over the years. What has happened to the quality?
Summary: Initially I was happy with these headphones. The sound initially seemed great. Then I started noticing I had to put the volume up when traffic was loud around me. I never needed to do that with my Klipsch headphones.
Summary: It took me all of seconds to realise these suffer from the same problem of every in-ear headphone I have ever tried. Maybe it is because I max on the spoken word rather than Lady Gaga, but the most obvioius features I noticed with the MM 30Is was the cheap tininess of the sound and the extraordinary...
