Bose QuietComfort 25 vs Koss KSC32P FitClips

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.

The bass is pretty powerful and gives a lot of thump to the music. Listening to hip-hop, EDM and dance tracks with these will most certainly get you going as you work out or run.

The highs and mids are clear, but recessed so the headphones will not be able to provide you the utmost in detail.

Flexible ear hooks are integrated into the design. You can twist and bend the hooks to conform to the shape of your ear, and will certainly help to keep the FitClips in place even when running or working out.

Getting sweat or small splashes of rain or liquid won't damage these headphones as they are splash resistant. You will still want to make sure that they do not get soaking wet or get submerged in water, as such situations can still damage the headphones.

An in-line microphone along with a one button remote is integrated into the cable so you can easily answer/end calls when needed.
