I received these from JBL for an unbiased review. The premium look and feel of the Endurance PEAK was apparent as soon as I opened the box. The charging case is very nice, and feels good quality without being heavy, which is surprising for the level of charge it keeps. I’ve been wearing these for at least 45 minutes per day for a week, and not had to charge the case once; It’s actually still showing (via the four lights on the front of the box) as above 75% charge remaining! As for the earphones themselves, firstly let me say I’ve never really been a fan of the in-ear type, preferring the earbud style for better comfort. I found the Endurance PEAK a little awkward to locate correctly in my ear the first couple of times, but now I’m aware of the angle/direction required, it’s no problem. As I’ve stated before, I’ve been using these for around 45 minutes per day for around a week, and find them light and comfortable, with no discomfort whatsoever. Once Bluetooth has been set up, they connect automatically to my Huawei Mate 20 Pro as soon as they’re removed from the case, taking just the 3-5 seconds it takes to remove them from the case and put them in my ears. Perfect! As someone who wears glasses all the time, I thought they might battle for space behind my ear, but that’s not the case as the ‘hook’ part hugs the edge of the back of your ear, rather than the side of your head. I found the sound wasn’t quite optimised in my left ear, lacking bass somewhat, but found that changing the angle they sat was the problem. A swap in size of the rubber tip on that side solved that. For the size of the units, the bass is surprisingly good, and the treble isn’t ‘tinny’, as I’ve experienced with other earphones. Overall, while I still feel a little awkward about having something actually IN my ear, rather than resting in the ‘outer’ (more a squeamish problem on my part – ever seen The Wrath of Khan?), for sound quality, connectivity and comfort, I would choose the JBL the Endurance PEAK over my old earbud type every day of the week.

These wireless earphones are on par with my 40mm pioneers, i literally gave my pioneers away - They are very sleek, light weight, comfortable and very useful! No need for straps like other wireless headphones as they stick to your head with the POWERHOOK design, I really love them - You can't even feel them after a few mins. Battery is ok but you get a mobile recharging dock which will extend the life of the product as the day goes by. Bass is just right! I didn't get any distorted bass from a windows computer at high volume or a mobile phone/laptop or tv, they really did a good thing to enable these to really excel in audio quality, Congratulations JBL on making such a cheap,reliable, comfortable bit of kit - They will surely keep me entertained for a long time.

[This review was collected as part of a promotion.] What can I say, another fantastic product put out by JBL. I love these babies! As soon as I got then I read the Instructions and off I went for a run. The magnetic on/off feature is awesome now I don't have to remind myself to turn them off. Another cool feature is the finger touch volume control. Just a slight slide of the finger on the right earbud up or down while running, biking, or at the gym is a life saver. Water proof, sweat proof, and wireless = Outstanding. Now onto the case. It comes with a tiny well build chageable case the holds the buds in place as it charges them. You're given a lightbar in the front to show how much battery life you have left. It also comes with 3 sets of soft rubber ear inserts and the iconic orange USB charging cord. All and all I am a happy customer and look forward to the next amazing thing they come up with.
