• 【Better ANC Technology】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.
• 【Superior Sound Quality】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.
• 【30 Hours Battery Life】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.
• 【Accompany You Anywhere】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.
• 【Free Airplane Adapter】An airplane adapter is also included so that you can immerse yourself in music without disturbance on a plane for any trip. Now you could enjoy your favourite songs with your exclusive ANC headphones.
