Jaybird X3 vs Bose QuietControl 30

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.

You can get around 8 to 10 hours of use from a full charge.

The earpieces won’t easily fall from your ears when using these on the go. You get Bose’s StayHear+ wing tips which securely fit inside the ears. Also, since the noise cancelling electronics are in the collar instead of an inline module, there is not a lot of weight that pulls down on the earpieces.

While the noise cancelling does not eliminate all of the ambient noise, it does a good job of preventing most of it from mixing in with your music. With the audio turned up to a good volume, you aren’t likely to hear your surroundings except for the loudest of sounds.

You can dial in the level of noise-cancelling that you want using the Bose Connect app which is available for Android and iOS. This gives you more flexibility with active noise cancelling compared to other earphones.

The bass of the Quiet Control 30 sounds full, with good punch and power. It doesn’t add any bloat though, preventing the sound from getting too muddy. The mids are quite forward with a slight boost. Vocals and guitars can easily be appreciated, though heavy guitars may sound quite aggressive due to the slight elevation. The highs are clear and offer a good level of detail yet do not get harsh in any way. These earphones are good for general music listening, and should excel in vocal-heavy tracks.
