What's Digital Active Noise Canceling Technology?
Digital Active Noise Cancelling (ANC) Technology is a method used to reduce unwanted noise in digital signals, such as audio and communication signals. It uses algorithms to analyze the incoming signal and generate an "anti-noise" signal that cancels out the unwanted noise.

Are the volume controls awkward to press?
No, they're easy to press.

Can these anc headphones connect to a TV easily? Or are they dedicated to other devices such as cellphones, etc...
It should connect easily if your TV has a built-in Bluetooth. You would need a Bluetooth transmitter if your TV doesn't have a Bluetooth function. The package also has a standard 3.5mm AUX cord that you can plug into devices without Bluetooth.

Does it leak sound? For example, would others hear my music in a quiet space?
Pretty secure over-ear headphones, they are over-ear designed so they fit securely around the ears. No noticeable sound leaks unless they are not properly seated on ears.

Do these e7 noise canceling headphones need to be charged to use in wired mode?
No, only in wireless mode need to charge the headphones.
Important Tips:
1. The Microphone only works in the Bluetooth mode.
2. The ANC function only works in Bluetooth mode.
