The Whirly Wisps, though they are an all-silver design are not harsh in any way. What is really amazing, considering the small gauge of the silver wire used, is the full range of sound. I found nothing lost in the lows and the high end was extended and detailed without hurting my ears. I am a headphone listener, 98% of my music is classical, and I am an experienced listener and have owned/auditioned a number of cables. For the price, these are a really nice find.

Construction is delicate, but with care they should last a long time.
