I've been using these for the past 10 years or so and have been extremely happy. They work perfectly with my N900 (standard, Nokia connector) and my Jolla (non-standard, Apple connector). The volume level is good and so is the background noise isolation, which is my main reason for using them at work (an open-plan layout). The only drawback one might consider is that they have no microphone and no buttons to control the playback. But they do have an inline volume control.
