Boasting Active Noise Cancellation the E9 are a good looking and solid set of cans that are not only lightweight, but last for up to 30 hours on a single charge. Here is the blurb from Amazon:

Mixcder’s self-schemed chip achieves superior Active Noise Cancellation (ANC) by using a wider frequency range EQ adjustment to counteract bandwidth so you can appreciate a serene listening experience.
The sound quality is enhanced as well since we upgraded the headphone speakers. It sounds well-balanced with a decent level of bass and shows a great performance from mids and treble.
The Rechargeable battery provides up to 30-hour playtime in wireless mode when it’s fully charged. Or it could play music with ANC for 3 days if you connect E9 to your device by the included audio cable.
The rotatable and foldable design makes it easy to pack and carry. The ultimate soft foam and protein leather ensure a comfortable experience at any time. It’s designed to accompany you wherever you are.
