AKG K391NC - Pros & Cons

good build quality and nice visuals
decent sound cancellation system
interesting design
and an excellent audio performance
sound great and isolate the listener well

Having no volume or music controls is always a deal breaker
all-metal enclosure construction makes them seem ultra tough
unwanted ambient noise and excessively loud people
active noise-canceling feature
the compartment is still a little annoying
noise cancellation circuitry
Sony pair was overpriced and underperforming
older mini-USB charging port
The cable is black and the rest of the accents are a deep gray
less-expensive noise cancellation circuitry
overall noise reduction is not as powerful as with some of the leading options
s no external compartment for in-ear noise cancellation
the passive mode is less powerful when compared to the active mode
lack a functional 3-button remote control
