COWIN SE7 had been professional manufacture that focused on the ANC headphone for years.
The SE7 had grown with customers for almost 2 years. As a type of mature ANC product, usually, it sold by $109 most of the time. We still name it SE7 today while we continuously improve it according to customers' feedback.
If you are planning to purchase the ANC headphone but still do not make the decision, it worth your money.

Saying that i have a pair of Cowin Blutooth headphones and have had for years, never let me down once apart form the BT being "open" leading to some random music being played through them when i am on the train.
