I find the JBL Endurance Zone earbuds great for running. I wear them snugly over my ears and can hear everything around me thanks to the open-ear design. However, I have to get used to this, and they're not always comfortable.
Open-ear design The Endurance Zone earbuds have an open-ear design. This means they don't block your ear canal. They sit just in front of it, so you don't feel isolated from your surroundings. I especially notice this at lower volumes. While running, I can hear people talking to each other and cars approaching well in advance. This is a big advantage if you live in a busy city. At volumes above 50 percent, I find this more difficult. I also have to get used to the design. I know the earbuds are secure because of the ear hooks, but it doesn't immediately feel that way. The earbuds have a matte finish. This makes them feel comfortable and prevents dirt from sticking to them.
Good sound Open-ear earbuds often produce less deep bass, but this isn't the case with the Endurance Zone earbuds. I hear solid bass and clear treble in most music genres. For example, I can follow the entire bassline of a pop song, and I can hear every guitar part when I'm listening to rock music. In most genres, the bass, midrange, and treble are also well-balanced, and I enjoy clear sound. The earbuds struggle a bit more with intense music, where a lot is happening simultaneously. Think of metal, where you hear various guitar effects, the drummer hits hard, and the bass is even more prominent. In those cases, I find the sound balance less good, and I miss some details.
Long battery life These earbuds have a decent 8-hour battery life. There are earbuds with a longer battery life, but I find this more than enough. I use them all week during my runs without having to charge them. The wireless charging case provides another 24 hours of battery life, and after just 10 minutes of charging, the earbuds already have enough power for another 3 hours of listening time. In short, I'm not worried about the battery life of the Endurance Zone earbuds at all.

Fantastic earplugs. It takes a little getting used to putting them in at first.
But after that, they're perfect.
I often wear just one at work, but I also wear two. You can still hear your surroundings clearly. And by that, I mean when people talk to you, you can hear them clearly. And the sound is good too.

The purple JBL Endurance Zone does what it's supposed to, but it stands out in a few areas. The case looks a bit cheap in this color, though it functions perfectly. The earbuds connect quickly and without hassle to your phone, and the sound is decent for everyday podcasts or audiobooks.
However, when running along busy roads, the sound almost disappears due to ambient noise. Safe, but less pleasant if you want to keep your audio. The fit is otherwise comfortable enough for athletic sessions.
