JLab JBuds EPIC vs Jaybird X3

Sound quality is good enough for enjoying a wide variety of music genres. This comes with the advantage of having sport-related features like special tips for improved fit as well as splash resistance.

The low end frequencies are what stand out from the sound signature. Bass goes deep and is pretty forward too, so you can clearly hear and experience the thump from your music.

The highs are also crisp and airy, giving a lot of detail. This combination results in these headphones having a fun sound.

There is a one-button remote which allows you to play/pause tracks as well as answer/end calls. This can be very convenient when used on the go.

Little rings called "Cush Fins" wrap around the earpieces, and give extra grip, and prevent the pieces from falling out. Also, these Cush Fins are quite soft and flexible so they do not have too much of a negative effect to comfort.

There is a one-button remote which allows you to play/pause tracks as well as answer/end calls. This can be very convenient when used on the go.

A fairly large, zip up carrying case comes included and should give these extra protection when taken on the go. You can just chuck this case into your bag without worrying about your headphones getting damaged.

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.
