Is the charging cable included with the JBL Endurance Peak 4?
No, the charging cable is not included. The box contains the earbuds, the charging case, an enhancer, three sizes of ear tips, the warranty leaflet and the quick start guide. So you will need a USB cable — the one from your phone will do the job.
Does the IP68 rating also protect the charging case?
No, and the difference matters: the earbuds are IP68, the case only IPX2. In other words, the earbuds withstand sweat, rain, salt water and sand, while the case only tolerates a few drops. Keep it dry, in your bag.
How many hours do the Endurance Peak 4 last with noise cancelling on?
8 h from the earbuds alone, with noise cancelling on, and 32 h in total with the case. With it off, this rises to 12 h and 48 h. The 48 h figure often highlighted therefore assumes noise cancelling is off: 8 h is the figure to remember for everyday use.
How long do they last on phone calls?
Up to 5 h with noise cancelling on, 6 h with it off. The mic and voice processing use more power than simply playing music, which explains the gap. A 10-minute quick charge also gives you 4 h of listening.
Do the earbuds stay in place during an intense workout?
That is the heart of this model: JBL oval tubes combined with the TwistLock locking design, with an ear hook made of liquid silicone with memory wire that bends to fit every ear shape. Each earbud weighs 10.5 g, i.e. 21 g for the pair.
How do calls hold up when running outdoors on a windy day?
Three mics per ear, six in total, pick up your voice and remove noise coming from elsewhere, while a beamforming algorithm reduces the background noise. The windproof design also limits the distortion caused by air friction: this is precisely the use case it is designed for.
Can you find the Endurance Peak 4 if you misplace them?
Yes, through Google Finder, which locates them from an Android device. The case also has a lanyard hole so you can attach it to a bag: the best way to avoid putting it down somewhere and forgetting it.
Can they be connected to two devices at the same time?
Yes, multipoint connection handles two Bluetooth devices simultaneously: a workout video on your tablet no longer stops you from taking the call coming in on your phone. Google Audio Switch also switches automatically between Android devices.
Is pairing quick on Android?
Yes: the Endurance Peak 4 support Google Fast Pair and pair with an Android device in a single tap. The connection uses Bluetooth 5.4, with the A2DP, AVRCP and HFP profiles.
What can you adjust in the JBL Headphones app?
The level of adaptive noise cancelling and ambient mode, and the sound profile to suit the intensity of your session — light, moderate or intense activity, or a custom setting. A relax mode also offers five soundscapes, from ocean waves to a crackling fire. Personi-Fi 3.0 maps your hearing profile there too.
Can you hear traffic without taking the earbuds out?
Yes, that is what Ambient Aware mode is for: it lets outside sounds back in and even lets you talk to someone without removing the earbuds. Four noise-sensing mics handle the adaptive noise cancelling, and the levels can be adjusted in the app.
How good are the Endurance Peak 4 drivers?
10 mm dynamic drivers, 16 ohms, 108 dB sensitivity at 1 kHz over a frequency response of 20 Hz to 20 kHz, with sound pressure capped at 95 dB. JBL Spatial Sound also widens the stereo image, whether for a film or a workout.
Can they handle the heat of a workout in full sun?
The stated maximum operating temperature is 45 °C, and the earbuds are specified as resistant to high temperatures as well as high humidity. Together with the IP68 rating, this covers most conditions of an outdoor workout.
Are these JBL earbuds new and under warranty?
Yes, new and genuine, with the invoice serving as the warranty document for
1 year. Full specifications are given in the manufacturer's
datasheet.
