If compared with the Bose model above, the AKG K391 still has a lot to grow, but overall it is one of the best noise cancelling headphones.
They show themselves well on board airliners and on public transport seats, successfully drowning out low drone, white noise and other background noise, while with voice it can not cope.
The battery is even more tenacious than the Bose, and it lasts about 40 hours on one charge.
Reliability of construction
The construction is made of aluminum, and the build quality is at an altitude. The aluminum shells of the ear cups, the thick rubberized wires securely attached to the battery and the noise-canceling device – you will have to try to find flaws in the design.
AKG K391 NC has a design more approximate to vacuum headphones, whereas Bose QuietComfort 20 is more similar to the overhead best noise cancelling headphones. Therefore, they stay in your ears exactly until you move actively, which makes them not the best choice for sports training. The ear pads can be replaced with foam rubber for better convenience, although the original silicone is very good.
The microphone works perfectly in call acceptance mode, and you can easily connect to any devices on the iOS and Android platform. Do not expect from him the quality of recording as in a recording studio, but to talk with a friend will come down.
Any audiophile will certainly agree that AKG K391 NC sounds better than Bose SoundQuiet 20, as the sound is more balanced.
While Bose has pronounced bass and high frequencies, AKG has a more balanced sound profile. It also can not be compared with typical audiophile devices, although the sound quality is closer to them than Bose.
With the noise canceling mode turned off, the sound drastically loses its detail, but it’s worth turning it on, as the sound picture changes dramatically for the better: high ones become clean and pronounced, acquire a warm tint, the middle is not darkened, and basses become elastic and clear.
In the end, if you do not want to spend a lot of money on Bose QuietComfort 20, but want to get similar noise reduction characteristics with a high build quality and an improved sound profile – safely take AKG K391.
- noise cancellation is better than average;
- high build quality;
- balanced sound.
- a bit bulky because of the battery;
- The sound still does not reach the best noise cancelling headphones.
