The JBL Endurance Peak is a great pair of earbuds for intense athletes who require that their earbuds stay in place during all sorts of demanding movements. Anyone in search of a pair of earbuds that will be just as home in the gym as it is out of the gym will want to turn their attention to other...

  • +

    Secure fit, Mono mode with either earbud, Comprehensive touch controls, Workout-friendly sound quality, IPX7 rating

  • -

    Microphone, Hooks get caught on masks and helmets, Bulky buds and case

The JBL Endurance Peak II are impressive for sports and fitness. These lightweight sports-oriented in-ears have a very stable fit thanks to their ear-hook design, so they shouldn't fall out of your ears during your workout.

  • +

    Well-built, portable design., Impressive stability.

  • -

    May feel fatiguing after long listening sessions.

I like that they stay in place, and don’t fall out when I’m sweating or bending over to pick something up. Also I have problems with other ear devices that hurt the inside of my ear’s & these don’t. I really like them!

Easy to use fits good, very little bass . Battery life is 4to 5 hours . Charger case works fine . Overall easy out of the box. Wish they had a better bass Range to complement the great mid and high range

Third JBL earbuds I have purchased for gifts. Love them

15 August 2021

Bought this thinking would be best for my iPhone and honestly when it did wanted to connect it was good quality with the sound and just perfect only flaw was it did not wanted to stay connected to my iPhone and quickly got discomfort from using them for a while but if you have an android or any...

The quality and appearance of this fine product works like a charm without all of the hassles of making connections to your calls or what have you and yes it's a must have product no question.

10 March 2022

So I bought a little over a month and I hardly use it, not because I don’t wanna but the thing pair properly, only the left side pair, which sucks, and they’re no proper solutions on YouTube to help.

These headphone fit well and have great sound quality, but they are generally difficult to use. They don't connect to my phone consistently, I had to reset them several times to correct the balance (the left ear phone was super quite, the right super loud ), and they occasionally don't connect to...

I have used many different types of headphones and these are so nice. They are convenient, they work well and I love how they automatically turn on when you put them one. The case/charging station is really nice.

I love my new head phones!! Great sound, perfect fit . They don’t wiggle out when running.

2 May 2021

These are ridiculous to charge. They don’t fit well into the charging case, so it’s easy to think they are charging when they are not. They are also not comfortable. After 4 hours (at work) they start to hurt the back of my ears, and are not as easy to wear as the previous Endurance Peak model.
