These earphones are an excellent value. I obtained these earphones which work with a wide range of music in clear highs, middles and lows, with no distortion or buzz. I use them frequently when exercizing. I can crank up the music and tune out the world. They are so good, that sometimes I worry about my eardrums. That is when I turn the music down. They are well made, and durable. I would buy another set if the need arose. If you are still using the earbuds that came with your ipod, you are missing out on a alot of musical enjoyment.
