Monoprice MHP 839 ( 108323 ) vs AKG K391 NC

The mids are the star of the MHP 839’s sound signature. They are forward and have good clarity, making vocals and guitars sound really prominent, and gives the overall sound a distinctly warm feel.
The bass is very good. While not very forward, it is full, has good punch and comes off as quite natural.
The top highs are rolled off, which may muddle some of the music’s details. However, this also results in a smooth sound, as there is little to no harshness.

You can wear these the conventional way, or you can also choose to use these DJ style, where only one ear cup is held to the ear.

One cable is thinner and shorter which is great for mobile use. The other is longer and thicker which should work better when using the headphones indoors.

The cable is connected to the left ear cup via a 3.5mm cable, which can easily be removed. Storing the headphones or replacing a broken cable should be very easy to do.

The MHP 839 is very versatile. The sound signature is enjoyable, and can work well with a variety of genres. It also offers good passive noise isolation for studio/DJ use. The collapsible design with removable cables make it easy to bring on the go. This combination of features is rarely seen in the price range.

The accessories included are all very useful. You get two 3.5mm headphone cables, a USB charging cable, silicone ear tips, a travel pouch and an airplane adapter.

You can easily replace the 3.5mm cable should it get damaged. You can detach the 3.5mm cable from the control module which is very convenient. Other noise cancelling modules have fixed cables, so you’ll have to replace the headphones should the cable get damaged.

You can take calls with these headphones on. A microphone is integrated into the remote which makes answering calls fast and convenient.

A good amount of noise will be blocked from mixing in with your music. Loud, low-pitched sounds may still be clearly heard though

You aren’t likely to have issues using these on the go. Most active noise cancelling in-ear headphones have large control modules, while the K391NC has a fairly compact and light module. You can easily use these headphones while walking and comfortably enjoy active noise cancelling with your music.

The highs are quite detailed, yet do not get harsh. The mids are slightly forward, so vocals and instruments can easily be heard. The bass is not very powerful but is tight, so you’ll get decent punch from your music.
