Most wearable products today are heavily focused on fitness and activity tracking. From counting calories to monitoring heart rate, these specialised fitness bands can do quite a lot. Even smartwatches today try to do at least some of these things.

Accurate heart rate sensor; Decent bass; Superb fit

Shrill treble; Expensive; Low volume; Average sound quality

I was never able to wear earphones before as they always fell out of my ears and the wire was always an issue. Not any more. These are terrific. Very comfy, Great sound with lots of bass and quite a good range too, 6-7 meters approximately.

The Jabra Sport Pulse, in my opinion, is one of the best - if not the best - set of workout earphones on the market right now. In addition to delivering music, it also measures your heart rate, which is a really handy feature for sports enthusiasts.

After using the Sport Pulse daily for about three weeks in and out of the gym, I can highly recommend them to anyone looking for high-end wireless earbuds to bring to the gym, runs, or any type of outdoors physical activity.

This update is for the JayBird BlueBuds X , Jabra Sport Pulse , and JayBird X2's …all three wireless sports earbuds designed to survive the rigors of the most epic workouts. Or at least that is the promise/hope of both JayBird and Jabra .

Secure; comfortable fit; Well made; IP55 certified water-resistance; Good sound quality; Accurate heart rate; Solid workout/partner app; Useful voice prompts

Expensive; Mediocre/flaky battery life

Sound quality and range are great but it's the HR training features which make this an essential for me now when running/training. The sensor does lose pulse quite often for only a second or two which can be quite annoying unless the sensor status notification is switched off.

These lightweight, Bluetooth headphones have a neat little trick: they'll monitor your heart rate while you're running a trail or biking up a mountain. And they do it surprisingly well. By Duncan McLeod.

Very disappointed. It was great till it worked which was only a couple of weeks. Feels like wasted my money.

The jabra pulse are fantastic, I use them daily with no issues ranging from skype calls and regular calls to movies, music and video games. Only issue I have noted is that they can NOT be charged through the computer via a USB cable, they can only be charged via a direct-to-outlet cable.

Bluetooth pairs easily.good sound quality.
