Mixcder

Although the Mixcder E9 noise-cancelling headphones are cheap, they still use the most advanced active noise cancellation technology to eliminate noise. A 40 mm driver is used to provide the wearer with high-quality sound. The E9 also offers up to 30 hours of battery life, so don't worry about it running out of batteries on the plane or at work. Its rotatable design and compact carry case make it easy to carry.
