What customers say about "Key Specs"
JBL Endurance Peak True Wireless Bluetooth in-Ear Sport Headphones - Black
  • This in-ear headphones has exceeded all my expectations regarding sound quality.
  • Besides having an unbelievable sound quality, it is very comfortable to use, the battery life is great and the controls are very accurate.
  • I have had these headphones for two and a half months and use them 5 to 6 times a week at the gym. The battery life is amazing. I still have 2 bars left from the initial charge.
  • Great waterproof ear buds. I cycle a lot and these keep a secure fit and lasting battery on longer rides.
  • They last about 60 days of poor service, and battery life of about 2 hours. Never again will I trust this company and their products, what a disappointment.

What customers say about "Features"
JBL Endurance Peak True Wireless Bluetooth in-Ear Sport Headphones - Black
  • They are comfortable to wear and stay in place quite well. I have small ears so I need something to go over my ear to hold them in place and these work very well for me.
  • I've owned these headphones for a few months and they're incredible. If you don't play music on them while they aren't charging in the case, they automatically shut down to save battery.
  • Completely waterproof and just an all around awesome product. I love these.
  • The storage/charging case that the buds come with is also well-made and the whole system is easy to use, including the touch controls on the master bud (right) and Bluetooth pairing.
  • The bluetooth drops out constantly even after I replaced it. If I am in the gym or walking around town the bluetooth is very spotty.

What customers say about "Power"
JBL Endurance Peak True Wireless Bluetooth in-Ear Sport Headphones - Black
  • These things kick! Would totally recommend to any of my friends. Charging case is also very cool and well made. Fast charging!
  • Charging case is a bit awkward but does a good job with some configuration, i think all in all can recommend!
  • Thoroughly enjoy these headphones! Great sound quality, and they stay in my ears! Love the mobile charging case too! Great battery life and quick charging!
  • The JBL Peak earbuds are great, but the first time I got them the left earbud wouldn’t charge and pair with the master earbud.
  • The sound is low and awful - zero bass - the charging box doesn't work after a couple months making them useless trash.
