Summary: The ear buds are excellent; they provide high quality sound and are very comfortable. My only complaint is that the wire is a little awkward, but the buds are still completely worth every penny (and maybe a little more).
Summary: I bought these earbuds mainly to get a pair that fit in my ears. Regular earbuds will not stay in my ears. These come with 3 different size buds and the small fits well.
I have listened only to audiobooks so far and the sound is good. These earbuds block outside noise very well. I have been able to turn the volume down to 4 or 5. They even block out kitchen noises (I wear them while I cook) like running water and the spice grinder.
Summary: Well worthwhile upgrade and not too expensive. Emphasized lower end.
My only complaint after using these for the gym for over a year now is that the cord length is different from the split to the buds.
Summary: When researching which brand/model of headphones to buy it became clear that there are a lot of counterfeit Sennheiser headphones on the market - making it essential I bought mine from a reliable supplier e.g. Argos. On getting my headphones home I took the precaution of burning them in (playing music into the headphones at about half volume for 12 hours) with the result that the sound quality is very good for what are quite modestly priced phones.
