Rated 5 out of 5 by from Bionic Hearing is the future Had these for a few weeks now and I'm glad I have them. I'm used to other brands but JBL have stepped up their game. The new bionic hearing function where you tap the left ear bud to bring the volume down to a whisper and then i think the microphones turn on so you can hear outside the earbuds (the fit is so good they're similar to being noise cancelling *****they're not but are as good as*****) is ingenious. I suppose it needs it though because you can't turn the volume down on the earbuds like you can on some other brands, but they're simple in design but mighty in quality and sound. I opted for the larger earbuds, which were easy to change. They are a nice weight and dont fall out of your ears, not even slightly. When i'm in the gym i'm confident in their ability to stick in my ear. There's a minor lag when using certain apps on my phone, but i think this is a developer issue which should get resolved with a firmware upgrade, which i hope comes out soon. The case is sleek and clean, the earbuds magnetize to the case so they dont fall out. I put a full charge in the case and didn't need to recharge for over a week, and I use for about 4-6 hours a day at the gym and on my commute to the office. Great product, just needs a firmware update to stop the lag on certain apps. But they're amazing just got the Bionic hearing. I dont think it will be long until others clock on and do the same.

Rated 5 out of 5 by from Amazing I was lucky enough to test these headphones they come in a lovely case which charges and keeps them safe each earphone is labelled L and R so you don’t have to mess about figuring which one goes where. They are comfy and sit in the ear well. The sound quality is Amazing and if you have them on full you literally can’t hear anything around. The charge lasts ages too I used these alot At the gym and they have worked really well for me they are so easy to connect to the phone as it shows the headphones straight away on Bluetooth. Can’t rate these high enough they are brilliant.

Rated 5 out of 5 by from Nice sleek design I was gifted these a few weeks ago so thought i would like to review them. On first sight i loved the look of the nice packaging and sleek design. The instructions are not amazing but once i worked it out wasn't as complicated as I first thought. They nicely slide out of their handy little charging box so can be carried around safely while not in use and charge up on the go. I then came to the actual earbuds on first sight they seemed very chunky and quite heavy so i wasn't sure how comfortable they would be. After a little adjustment ive managed to get them in but sometimes it feels like ive got my eardrum sucked in and if i dislodge it might follow with my inner ear. I must admit it took a few days to feel comfortable and a few days for them to stop falling out but finally its ok. Then to the sound experience, im a huge drum and bass ragga fan so i find this particular type of music gives a good range from tops to mids to bass so is perfect for testing any type of sound equipment these ear buds are no exception. Wow what can I say except it reaches everywhere you want it to reach and some, in true JBL style i think they have once again put it out there so well done i definitely look forward to seeing how well they can handle time. And lastly battery power so far ive only charged the case once and every time you put the ear buds back they go on charge so its a bit difficult to say how long they will last something that for most people wont be a problem but id like to understand maybe something that could be done on the next ear buds?

How does this compared to the jabra elite 65t

Asked by: GavinKillerz
I have both. I would say that the sound quality is similar, as good as my Beats over the ear headphone. Bass is a little better with JBL. You can use the equalizer in Jabra, not in the JBL. JBL really stays in place all the time, even when running pace 4. Controls are better placed in the JBL. My guess is that if you are looking for something related to sports you should go for JBL.

Are you able to swim with these?

Asked by: KMT4
IPX7 grading, which ensures 30 minutes listening at one metre of depth. I haven't tried mine in a pool yet. I would probably spend a little more time getting the correct sizing on the ear buds to ensure a tight seal before trying. Also you can't store any music in the headphones either, so you would need your phone to be within Bluetooth range. So theoretically it could work for a pool workout with your phone nearby, not open-water unless you also had a waterproof phone case attached to you.

What are the controls like on the earbuds? Volume, skip tracks, answers calls?

Please describe all the controls the earbuds have.
Asked by: Jayda18
The right earbud controls the playback as well as accepting/denying a phone call. There is no volume control options on the headphones, the volume must be controlled by the device.

Are the headphones normal making a noise when being paused or listening to music quietly?

Whenever I hear music, the right headphone, not the left one, makes a small noise, something like a swoosh. It can be quite irritating. Is the noice normal or shall I send them back? It is my first day using these headphones.
Asked by: Richardgregor
When powering on and powering off, the UA True Wireless Flash headphones make a sort of whooshing noise. This does not usually happen during playback after both headphones are connected.
