COWIN E7 Active Noise Cancelling Headphones Bluetooth Headphones with Microphone Deep Bass Wireless Headphones Over Ear, Comfortable Protein Earpads, 30 Hours Playtime for Travel/Work, Black
Black plastic case, leather edge.
Plastic parts for metal.
On the headset with the Cowin logo, a triangular insert combines three buttons and an LED indicator for Operation. The NFC tag is also hidden here for a quick connection to the phone. My Blackberry KEYone connected directly. At the bottom there is a three-position button “off”,” on” and “ANC”, an audio output of 3.5 mm and a hole with a microphone.
On the second ear, the triangular insert is purely decorative, and at the bottom there is a micro USB port.
The leather bag is quite good.
Headphones work via Bluetooth or cable.
You need to set the switch to BT or ANC mode, then find the ears via Bluetooth. If the phone is equipped with NFC, simply connect it to the headset where the buttons are located, and the phone will find them and make a connection.
I want to congratulate Cowin: turning on the headset and connecting via Bluetooth is very fast, 1-2 seconds. My Sony Sport devices connect for at least 5-7 seconds.
Nothing special: a short press + or-changes the tracks, a long press changes the volume. The tip of the triangle with the LED acts as a play / stop.

You need to put the power button in ANC (extreme) mode. It works very well: the buzz of air conditioners and fans simply disappears. It helps a lot in the office, gets rid of the unfamiliar unpleasant background. At the same time, similar voices and sounds do not disappear, this is a function of active noise reduction.
ANC works even when there is no music. That is, you can turn it on and enjoy the silence. ANC does not create squeaks or extraneous noise, which is very pleasant.
Very loud sound, safe bass, upper and lower frequencies are usually transmitted normally. No buzzing, no Bluetooth delay either. I do not have equipment for accurate measurements, but the sound does not cause rejection. There is also no hiss or squeak in sleep mode, unlike cheap Bluedio models.
With Active Noise Reduction, it was not possible to crash the battery in 5 hours, I did not try again.
They turned out to be light, comfortable and with excellent noise reduction. Cowin-well done.
