If you are looking for a pair of nice looking over-ear noise cancelling headphones with long wireless range, check out the REVOLUTION headphones by 66 Audio!
The REVOLUTION headphones feature a huge Bluetooth 4.1 wireless range (over 65 feet), as well as active noise cancellation (ANC) technology and NFC (Near Field Communications) technology.
You get NFC in many Android phones (i.e. Alcatel Idol 4) which means if your phone has NFC, you can automatically pair via Bluetooth by simply placing your phone on the NFC area of the REVOLUTION headphones.
The REVOLUTION headphones feature a large Multifunction button that allow you to perform several functions. You can receive and end phone calls, as well as reject phones calls and redial the last number by pressing the Multifunction button in different ways.
To reject a call, press and hold the Multifunction button for a couple of seconds. To redial the last call made, quickly tap the Multifunction button twice. To mute the microphone during a call, press and hold the volume button for a couple of seconds.
When the battery is low, you will see the LED flashing red as well as hear an audible beep every few seconds.
Charging the REVOLUTION headphones is done via micro USB cable so, you connect one end to your desktop computer or USB wall adapter. While charging the LED will show solid red and will turn off when fully charged.
If you don't have NFC on your phone, you can also pair the REVOLUTION headphones manually with your smartphone. Simply press and hold the Pair button for a few seconds until the LED indicator starts to flash both red and blue (you will also hear a an audible pairing tone). In the list of Bluetooth devices, the headphones will show up as "66 REVOLUTION".
After a successful pairing, the REVOLUTION headphones will remember the last paired device, and will connect automatically after being powered down.

The volume buttons also double up as skip track buttons. To skip tracks, simply press and hold either volume button for a couple of seconds. As far as adjusting volume, one short press will adjust one interval. When maximum or minimum volume is reached, the REVOLUTION headphones will beep. To Play and Pause music, press the Multifunction button (located on the side of the left ear cup).
As mentioned earlier, active noise cancellation (ANC) is one of the features you get with the REVOLUTION headphones. The ANC feature does a good job at drowning out background noise, including noise nearby, which is great for office and airplane environments.
If you haven't owned a pair of active noise cancellation headphones, the best way I can equate it to is to wearing ear plugs. The minute you turn of the ANC feature, it feels as if you've just plugged in a pair of ear plugs. Outside noise gets blocked, allowing you to listen to music even at low volume.
The technology behind active noise cancellation (also known as noise cancelling) is pretty nifty too. Active noise cancellation works via a tiny microphone in the ear cup that listens out for background noise while cancelling the noise by sending out an opposing electrical noise wave that literary cancels out the incoming noise. Pretty cool stuff, isn't?
66Audio's packaging presentation of the REVOLUTION headphones is also top-notch and includes also a detailed user guide:
