Monoprice MHP 839 ( 108323 ) vs Bose QuietComfort 25

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 traveling case is small and provides room for spare batteries and other components. This makes it pretty portable, for those that can't or don't want to leave their headphones at work.

These headphones use a triple-A battery to power noise canceling. Should it run out of charge, it can easily be replaced.

With the feature switched on, you can really zone in on the music. Noise canceling is very effective at blocking out ambient noise, especially the lower frequencies. On a flight for example, engine noise is drastically reduced, as well as most of the sound from the conversations in your vicinity.

The QC25 feels comfortable even after wearing it for several hours. The pads go over the ear and feel soft, as the ample cushioning is covered with supple and high quality synthetic leather. Aside from the usual headband padding, it also has an inner Alcantara lining that feels really nice on the skin.

You have a number of options as to how you want to use these headphones' active noise canceling feature. You can either have the feature on or off while you are listening to music, or have noise canceling on without audio. This is a nifty feature if you just want to enjoy some peace and quiet when in a noisy place.

These headphones will not tire your head or neck out, even if you wear them for quite some time. These are pretty light at around 196 grams.

Sub-bass is a bit laid back, but the overall low-end production is punchy and with good extension. Mids are clear and forward so vocals, guitars and keys sound good with these. The upper treble is boosted, which results in good detail, but can also give harshness to the sound.
Overall, this is a really fun set of cans to listen to, especially if you just want to have a fun music listening experience.
