I have had two pairs of these headphones- my first pair stopped working after 4 weeks, the second replacement pair hasnt worked right out of the box (left piece failed to turn on). Terrible quality, I dont have any faith in the product and the jabra support is awful and have not responded to support emails or facebook messenger. I'm taking these back for a full refund tomorrow and putting this money towards the Sony brand instead.

I bought this in May 2nd because it looked like a good fit but the quality of my left earbud just dropped suddenly. It was working perfectly fine this morning at around 8:20 am on the 29th of May (to be specific,) and the quality was quite good as well. However, on the same day at 9:00 am, I can't hear anything through my left earbud and I don't know where I can contact the company for a possible refund or change. I didn't drop it once, hardly used it and always kept it secure in a safe place. I've only used the earbuds 4 TIMES since I bought it and it's already broken. I looked through other review pages and nearly everyone who bought this had the same problem.
10/10 would not recommend.
There are better alternate earbuds.

The good:

I think most people will find a good fit, sound quality is great for the class, don't fall out while running etc. Battery is great. Overall these are amazing except...

The bad:

Do some research and you will see the thousands of people that have had these, everything working great, only for the sound balance to mess up after a few months. There's no fix. One bud will be barely audible or will slowly quiet to mute while you are listening to it. Maybe resetting will help but, if like mine, it might not. I have been working through multiple returns with Jabra over the last few months.

In a nutshell, good set of true wireless ear phones, certainly geared towards someone into fitness, I should have gone for the 65 T active model, as I think this was more geared towards casual use and the buttons are far easier to push, on the elite sport, they dig into your ear canal and become very annoying.

I was so excited to buy these and be cord free but after two weeks I’ll be selling them and going back to my trusty Powerbeats 3’s, $100 cheaper, 3 times the battery life and at least double the volume. For listening to music the max volume on the Jabra’s is very sad and tech support is just as sad.

This is the first paid of true wireless headphones I have purchased. Having no cable between both headphones is truly a marvel. Setup was easy and they connect instantly to my phone upon being switched on. Control on headphone are functional and work well with Spotify. Charging case I think is a must for any true-wireless headphone setup.

I have been using these headphones for the last 6-months.

If you are willing to fork-out the extra for these headphones, it's well worth it over a $50 pair.

It is comfortable and easy to use and the charging case is a great feature. Heart rate monitoring is not reliable. Solid sound quality and build. Excellent Bluetooth connectivity. After the first time that you pair with them to your phone, the earbuds connects immediately when you take them out of their case.

After reading quite a few negative reviews for these I was wary on purchasing them. But after taking the time to get the correct fitment - ( I ended using different sizes of wings and buds in each ear) I am totally happy with my purchase. I wore these for the first time on a half marathon and they stayed put for the whole time not once did I think that they would fall out. I love the sound of them,
Granted they are hard to get in but once in they fit perfect.

Using these it becomes easy to cut the cord at the gym or whilst working out, it is easy to package and carry in it's small case, which doubles as a chargeable case giving many hours of battery life, sometimes it's possible to go a week without charging if you forget, can be charged quick and fast through USB. Highly recommended

These ear buds are great, battery life is great and lasts for ages, the handy carry box acts a s an extra battery backup, good led indicators tell when you getting low and also has good voice in ear instructions. Heart sensor is great and always able to pic up. sound is fantastic and good noise reduction as fits snug in ear. One minor point is they take a while to charge but will last weeks on a full charge if not used.

Do not buy! I enjoyed these for a while, but when they broke, Jabra did EVERYTHING in its power to ignore me. 6 calls with a MINIMUM 16 minutes on hold before picking up (twice after 15 minutes they just hung up on me). After finally getting something going they switched me over to email and now refuse to answer those emails. They’re trying to run out the clock on the 1 year warranty by ignoring me. Jabra doesn’t stand by its products and is NOT a brand to be trusted

I bought to exercise without annoying cords in the way; the sound quality is great, you can operate the volume and press pause and play by pressing the buttons on them while they're in your ear, they're comfortable, don't fall out when running, are waterproof so you can wear in rain, you can choose to let in outside noise for safety if you want to, one charge lasts ages, you can wear just one if you want to while you're at work, you can listen to music discreetly if you have long hair.
