I am commuting and driving only by bus and train to work. The standard iPod earphones are wg. the high ambient noise in bus and train absolutely unsuitable (unless you put them on very large volume, but I have my ears just do not care). So I went to look for something that shields the traffic noise. This are ear-canal phones mE the best choice (have experimented with other types of headphones). For the CX-300 I chose because of the good test results (eg, audio). Correctly inserted deep into the ear, of the environment virtually nothing more to hear (be careful in traffic ...), and I can hear wonderful at very low volume. The sound is similar to the original handset, where the bass is much better. At the beginning encountered pressure feeling I got used quickly, and the single-sided cable is absolutely not a negative - it is not true that the cable would pull the plug from one of the ears, with the right pad size sizten these things firmly. Cable noises only occur while walking / running / jogging, this Ohrkanalhörer are due to design very poorly suited since one extremely hears every step. So: The original listeners better still take the road to stop ;-)
