I bought these earbuds for use when travelling light. I have owned both Phillips and Sony noise cancelling earbuds in the past and this pair is by far the best. The battery life is sufficient for all but the longest flights. The noise cancelling works well for most background noise, but does allow some speech through (e.g airplane announcements). Not sure if this is by design. These are not a replacement for over ear noise cancelling headphones like my Bose quiet comfort qc25'sin terms of sound quality and noise cancelling, but they don't sit in the same space. The fact they are available in a range of colours other than traditional black or silver is a bonus.

I bought these to replace my Sony XBA-1Ps, and they are a wonderful upgrade. The strong bass that never appeared on the previously named model is plentiful here, and the detail in the treble is amazing up to 40KHz (Madonna's Frozen well worth a listen). Vocals are also strong. The noise reduction is good but not completely effective; in some ways it actually amplifies some sounds by cutting out others (such as train noise disappearing only to leave the sound of people talking coming through quite clearly, which is more irritating), though they are wonderful at cutting out external base (the real sound polluter).
