Jaybird X3 vs Bose QuietComfort 25

Exposure to splashes of rain or sweat won't easily damage these earphones.

The highs are crisp, airy and forward so detail presentation is very good. Bass is fast and controlled instead of boomy, so it does not muddy up the overall sound. The mids sound natural and do not get lost in the mix.
This sound signature works well with a wide range of genres and rock, pop, hip-hop and EDM will definitely sound great with these headphones.

The X3 comes with wing tips that you can attach to the earpieces. The tips enhance the grip of the headphones in the ear, and will help keep them secure even while you are running

The in-line remote will allow you to control music playback, adjust volume as well as answer/end calls.

Integrated into the remote is a microphone, so you do not need to pull out your phone should a call come in. Mic quality is pretty decent, and your voice should be easy to understand on the other line.

You get standard silicone ear tips in different sizes, along with a carrying case, different sized wing tips, premium Comply foam ear tips in different sizes, cable management clips as well as the charging cradle with micro-USB cable.

The older X2 model had bigger and heavier earpieces which made them prone to falling off, and also made it difficult to use the earphones with a helmet or a hat. The X3’s earpieces have been redesigned to be smaller, while the internal batteries have been moved from the earpiece to the remote. This helps keep the X3 in-place inside the ears and at the same time makes these earphones easier to fit under a hat or helmet.

The X3 gets around 8 hours of playback time from a full charge. This battery life is much more consistent compared to the previous model which had spotty battery life.

Signal quality is pretty stable with minimal distortion or drops, even if you are on the move.

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.
