    This is my first pair of in-ear headphones. I also own the Sennheiser PX100 and Sennheiser HD280 headphones. I have to say, for $70, the Sennheiser CX 300-II in-ears have rather great audio quality. Bass thumps and the highs are clear. The mids could be a bit better but boosting the proper frequencies with your audio player’s equalizer can improve the sound. Using the small sized adapters, I get a good seal, and after a little while I don’t even really notice them in my ears. I can’t comment much on durability, since I’ve only owned them for two weeks now, but they seem sturdy enough so far. Overall, I can’t imagine finding better quality canal headphones for this price. Definitely a good buy, whether you’re on a budget or not.

    I’ve used Sennheiser earphones for many years now, mainly because of the great quality of their products. That’s also why I turned to these CX 300 MK-II, when my Apple in-ear phones decided to call it a life after some 5 months of use. These are half the price of the Apple ones, and the sound quality is better by no small margin. They are very comfortable to wear, even after hours of use. They come with a selection of small, medium, and large interchangeable fittings, allowing one to find the ones best fitting your ear size. They also come with a small satchel in which you can carry them. This little bag, however, is nothing to shout about. I never use it, finding it nigh on useless.

    Highly recommendable. Very good sound for a small asking price.
