Over the recent years, Bose has invented a series that was supposed to be the definition of passive noise canelling headphones, but they were just awful, static, and uncomfortable. This specific series was the "quiet comfort" headphones and they consisted of the QC, QC2, and the QC3. Now Bose has made a new addition to the series the Quiet Comfort 15.

If you set out to find a good pair of earphones, you first need to figure out what qualities you are looking for and how much you are willing to pay. If you find a pair that are real comfortable and yet have poor sound, you will still not have what you are looking for. Not everyone puts the same value on the quality of sound, as some people want only the best. Other people can't really tell the difference anyway and any middle of the road pair of earphones would be fine for them.
If using a ladder I would recommend having an extra member to help you. Someone should hold the end of the ladder so you're supported and there is no risk of you falling or slipping. If the ground is too wet your ladder will sink into the ground which means the point of gravity will alter, also if the ground is too hard you may find the ladder will slip so it's always worth having an extra pair of hands.
