I have played keyboard for a few years, but I have always worn cheap, and sometimes not so cheap, ear buds so I wouldn't bother anybody else in the house. I was starting to get some crackle in the most recent pair of ear buds and I thought I would check Amazon for over the ear headphones that may be designed specifically for keyboard players. Even though these are Yamaha, I use them with my Roland FP-4. I was anxious to try them, and when I did I couldn't believe the sound. What sounded very plain through the earbuds sounds fantastic through these headphones. It really sounds like a piano when I play, or electric organ, or organ, etc. I just spent the last couple of hours trying out several of the voices available on my Roland just to hear how different they would sound. I would highly recommend these. The price is fantastic and so is the sound. One thing I need to mention, when plugged directly into my FP-4 the sound was very low. I plug my keyboard into a small amp and then plug these headphones into the amp. Otherwise, I wouldn't be able to hear the sound very well.
