Product Reviews

Average Rating:   3.5/5 stars      


 
 

Good noise attenuation, but poor overall sound.

by  nhunt ,  Apr 25, 2002
14 out of 14 people found this review helpful.

Cons: Sound quality is much worse than competing active NR headphones.
The Bottom Line: Way too pricey for mediocre quality sound.
This reviewer does not recommend this product.

11 out of 11 people found this review helpful.
Pros: stylish, comfortable, good sound suppression
Cons: Does not suppress very low frequency, mediocre sound, expensive, difficult to store.
The Bottom Line: If $150 isn't expensive, then this unit is a good product. If $150 is expensive, then this unit is not a good value.
This reviewer recommends this product.
Review: I've used three noise suppression headphones--Koss, Sennheiser, and Recton, and tested at the store about 10. For comfort and style, Sennheiser is tops. For sound suppression and sound quality, Koss is best.

One characteristic I would...
