Query: Lightweight, Excellent Sound

I purchased these headphones 8 months ago when looking for a pair of over-ear headphones for work and travel. These have exceeded my expectations. These headphones are super lightweight and rest comfortably on your ears, helping avoid the fatigue and irritation that can accompany several hours of listening. IMHO, the sound is crisp with an emphasis on the treble side -- not super for big bass.The design is relatively rugged while also easy to collapse and store in the useful travel case.Highly recommended.
