Awesome for IEM usage

Product Review

After hearing my bandmates w20's I decided to get the upgraded w40s. As the singer and guitarist I wanted more clarity and other reviews lead me down this path. Isolation is the key. They come with a ton of earpieces and using the thicker foam inserts for total isolation really let my tone ring true. Compare our FOH sound with my guitar and vocals and then the 240s in ear. Perfect. They maybe pricey but they work. If you are a working player using IEM's the westone cant be beat. W20 or W40
