The SE425 in ear headphones deliver great sound, are reasonable durable, and are hard to beat at their price point. They offer a dual driver, giving you more clarity and distinction between your lows, mids, and highs. They work fantastic as in ear monitors for live performance. I use them for live piano but have also found use for them with drumming. The SE425 fit comfortably and are pretty durable, I have had my pair for 2 years and just got them replaced! Overall a great buy and something I would recommend.
