Bose QuietComfort 25 vs SoundBot SB221

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.

Charging these headphones should not be too difficult at all. These headphones use a micro-USB to USB connector, and the port is very common nowadays.

The headphones' functions are really easy to control. There are 5 buttons present on the right ear cup which includes the answer/end call button, volume up and volume down buttons as well as next and previous track button control.

Aside from being good for general music listening, these headphones can also be used for hands-free calling when connected to a smartphone. These headphones feature a built in mic which can capture voice and deliver this to the listener with a good level of quality. Also, the headphone features a receive/end call button for easy call answering.

These headphones are really easy to bring when you are on the move, as you can collapse these down to an even more compact size. You can fold the ear cups into the headband which will make it very easy to store these headphones or fit them inside a bag when taken on the go.

These headphones can provide many hours of straight, listening hours. Each full charge can give the user an average of 20 hours of audio listening.

These headphones are pretty convenient to use as they feature Bluetooth connectivity. This allows the headphones to wirelessly connect to a wide range of devices including smartphones, tablets, computers and the like without having to deal with long and potentially messy wires.

These headphones feature a very streamlined design with a slim, headband design and ear cups that are just at the right size to cover the ears when worn. This means that the wearer will be less likely to experience strain or pain on the head or neck due to the weight of the headphones.

These headphones are by no means audiophile grade, but produce sound that can be considered as okay for casual music listening or for watching movies/videos and the like. Bass and mids are present, but they really do not stand out. The clarity of the highs is okay, and can provide some detail but definitely is not crystal clear, with some minimal hiss present. Volume is also on the okay side, but these headphones are not able to pump out max volume levels without distortion. So while these headphones are not suitable for critical listening, these are good enough if you simply just want to hear the audio.
