Rated 4 out of 5 by from Honest review Having not seen many detailed reviews about this product, I thought it would help to give one for those looking to buy. Fit: - takes a little adjusting the first few times to find the perfect fit, but interchanging the different sized ear buds/wings is very helpful. You'll get it perfect within the first few uses. After prolonged and regular use, I found that one of my ears was a little bit sore, but could just be getting used to it, as it is very snug in the ear. There is zero moving around with jogging, cycling, jumping, gym etc. Put them to the test and you'll be very happy. Sound quality: - as good as you can get for true wireless - that's thanks to the quality of JBL. Good enough base as well as deep, full, sounds which makes listening a pleasure. Connectivity: - Sometimes the left headphone would come out of sync with the right, and so songs would be a bit jumpy. Simple fix by turning them both off then back on. Though didn't expect that to happen after only my second use. One tip I found was to take them both out of the case at the same time, not one by one, so that they can sync together to your phone straight away, or else one will sync to the phone before the other, and that's when they aren't syncing together. - Playback watching videos has a half second delay or so - slightly irritating if you want to watch a whole movie on a computer or iPad for example. Otherwise for things like Youtube it's not the worst thing in the world. - I didn't get any interruption or playback issues when jogging, as long as the phone isn't majorly moving around. If it's fixed to yourself or in a tighter pocket, then it isn't anything frustrating. Though other reviews have said more intense activities can disrupt the playback. Phone calls: - Having experimented with a few phone calls, I found that if the phone strays too far from the headphones, it's hard for the other end to hear you. The distance was not even that far before it got difficult - maybe an arms length made calls a little unreliable. Fixed by holding phone/taking out of pocket if it does play up. Even when I was on a treadmill and had the phone just resting on the display, there was a little bit of disruption. Probably going to be difficult to take calls mid exercise. Bionic hearing/ambient surroundings: - This is actually a very handy feature, I had them in my ears without ambient surrounding on, so the music was cancelling out all surrounding noise - then a stranger came up to ask me a question on the street which I couldn't make out, but one click of the left headphone lowered volume and opened up surrounding noise so that I could hear her better. Obviously with something snug in your ear, you still won't get perfect hearing, but enough that you don't have to annoyingly whip it out. Ambience is good when you want some presence of mind as to what's going on around you - e.g train announcements/traffic while you're jogging/general awareness of surroundings. Otherwise the noise cancelling is far better than your regular headphones. Charging case/headphone life: - True to its testimony, the charging case holds a solid 20hours, and automatically charges the headphones after popping them back in. Then they stop charging once they're fully charged, so that the saved up charge of the case isn't going to waste. You know they're charging as the headphones display a red light which turns off once at 100%, plus the four white lights on the case indicating how many full charges left. - Having used the headphones regularly for three days, it still had three full charges in the case ready to go. So the 5hrs held by the headphones themselves is very good. Length of usage is one of the features that I believe set these headphones apart from other wireless headphones. - The headphones are held in place in the case by a magnetic charge, but if the case is turned upside down or sideways, it's natural that they might slip slightly from their position and thus not charge. Before closing the case, make sure both red lights are on, to indicate both are charging. The left headphone for me sometimes needed some slight repositioning before the charge activating. Waterproof: - True to it's name, you can shower/swim/jog in the rain and they're fine! Just don't put them in the case whilst wet. Instructions: - One read through of the pamphlet and you quickly pick up the general idea of how they work. Then just memorising the right sequence of pushing buttons for the desired use and it comes naturally in no time! All in all a great product, only losing points because of the sometimes disrupted phone calls. 7.5/10

Rated 5 out of 5 by from Great Headphones These earbuds are awesome they sound good feel good and do the job they are meant to. Use them at the gym and everyday use and perform well. Only negative would be the case being a little larger then others, but the extra battery life is resulted of that

Rated 4 out of 5 by from Great Sound, Uncomfortable I purchased these about a week ago, and theyve lasted me very well so far, quality made and battery life perfect for my 12 hour a day listening needs not to mention the solid sound and bass. One thing they fail to do well is the comfort, I feel my ears hurting after 20 minutes of use, although if ignore it doesnt hurt until you take them out so they're useable. However more cutioning would be welcomed. Solid buy if your looking for good sounding and long lasting quality made gym earbuds.
