The JBL Endurance Peak II True Wireless are sports-oriented headphones with a distinctive ear-hook design that helps them stay on your ears during your workouts. Their bass-heavy sound profile adds an extra thump and punch to your favorite music. While they don't have an ANC feature, they do an amazing job passively isolating against background noises, so you don't hear chatter from people working out around you in the gym. Unfortunately, they may not be comfortable enough to wear for long listening sessions, especially if you have smaller ears. However, they're very portable, and their charging case makes it easy to recharge when you're on-the-go.

Test Results
The JBL Endurance Peak II have a distinct sports-oriented design that's similar to the JBL Endurance Peak True Wireless. They have dense, rubberized earbuds and thick ear hooks for stability. You can get them in 'Black', 'White', 'Blue', and 'Coral'.
The JBL Endurance Peak II are reasonably comfortable. They don't go too deep into your ear, which is nice. Also, the bendable wire on the ear hook lets you adjust the headphone based on your preferences. However, they're a bit bulky, and they can feel uncomfortable after long periods of use. Also, since you can automatically turn them off by moving the ear hook to touch the back of the headphones, listeners with small ears may accidentally turn off the headphones when trying to tighten their fit, which is inconvenient. If you're looking for more comfortable truly wireless headphones, try the JBL Live Pro+ TWS True Wireless or the Skullcandy Push Active True Wireless.
These headphones have passable controls. You can tap either bud to answer/end a call, and double-tap them to decline a call. Tapping the left bud once skips ahead to the next track while tapping twice skips backward to the previous track. Tap and hold either bud for two seconds to mute/unmute the microphone. You can slide up on the right bud to turn the volume up and down to turn the volume down. Tap the right bud once to play/pause, and double-tap to activate the voice assistant. However, the touch-sensitive controls don't have any audible feedback, and the sensitive surface is very small. As a result, when attempting to adjust the volume, sometimes the buds play/pause music instead.
The JBL Endurance Peak II are remarkably portable. They're small and lightweight, and they should fit easily into your pocket or bag. There's also a portable charging case to help protect them when you're on-the-go.
The case is decent. It's mostly made of plastic, but it doesn't feel quite as solid and durable as the materials used for the JBL Endurance Peak True Wireless' case. There's an LED light to show the battery level, and a locking mechanism to keep the case closed.
The JBL Endurance Peak II are well-built. They're mostly made of plastic, and the ear hooks are made from a hard, malleable silicone material that feels solid and durable. They also have an IPX7 rating for water resistance, though we don't test for this.
The JBL Endurance Peak II are impressively stable. They have a dual-locking mechanism to keep them from falling off your ears. You can wear them during your workouts, and they should stay in place.

The JBL Endurance Peak II have a bass-heavy sound profile. The extra thump and punch in the bass range is suitable for listening to bass-heavy music genres like hip-hop and EDM. The rest of the range is quite flat and balanced, so vocals and lead instruments are clear and present.
These headphones have excellent frequency response consistency. Once you get a proper fit and seal, you should be able to get consistent bass and treble delivery each time you use them.
These headphones have fair bass accuracy. The entire range is overemphasized, so audio has an extra thump and punch suitable for bass-heavy genres like EDM.
These headphones have superb mid accuracy. The entire range is flat and balanced, so vocals and lead instruments are clear and present in the mix.
The JBL Endurance Peak II have very good treble accuracy. Vocals and lead instruments are clear and detailed. However, the overemphasized mid-treble can make sibilants like cymbals piercing or painful.
The JBL Endurance Peak II have good peaks and dips performance. The slight dip across the low-mid and mid-mid ranges nudges vocals and lead instruments towards the back of the mix. The slight peaks in the high-mid and low-treble can make those same instruments a little honky or bright. The peak in the mid-treble makes sibilants sound piercing.
These headphones have excellent imaging. Their weighted group delay falls below the audibility threshold, resulting in tight bass and transparent treble. Also, the L/R drivers of our unit are well-matched in amplitude, phase, and frequency response. As a result, objects like voices and instruments are accurately placed and localized within the stereo image. However, these results are only valid for our test unit, so your experience may vary.
Like most in-ear headphones, they have a terrible passive soundstage performance. By design, they bypass the outer ear, which is one of the key components in creating a speaker-like soundstage. Instead, the soundstage is perceived as small and located within the listener's head. Their closed-back design means that their soundstage doesn't feel as open as that of open-back headphones like the Apple AirPods (2nd generation) Truly Wireless.
These headphones don't have any virtual soundstage features.
These headphones have an amazing weighted harmonic distortion performance. Even at higher volumes, audio reproduction is clean and pure.
These are the settings we used to test these headphones. Our results are only valid when using these settings.
The JBL Endurance Peak II have amazing noise isolation. They don't have an ANC feature, but they can passively isolate against a lot of background noise. They should be able to block out some bass-heavy background noises like bus and plane engines, as well as higher-frequency sounds like people talking nearby and the hum of an AC unit.
These headphones have an outstanding leakage performance. Escaping audio sounds very thin, and it isn't very loud. You can listen to your audio at loud volumes without really bothering those around you.
The JBL Endurance Peak II have an integrated microphone.
The microphone's recording quality is satisfactory. Your voice doesn't sound very deep or full-bodied, but whoever's on the other end of the line should be able to understand you.
The microphone has a middling noise handling performance. It struggles to separate your voice from background noise, even if you're calling from a moderately noisy environment like a busy street.
The JBL Endurance Peak II have a decent battery performance. They only last 6.6 hours off of a single charge, which may not last through your 9-5 workday. Fortunately, they have an auto-off timer to help conserve battery life, and you can automatically turn them off by moving the ear hook to touch the back of the headphone. Also, you can listen to audio using one earbud while the other charges, which is convenient.
These headphones don't have a companion app. However, if you're looking for app support, you'll want to take a look at their predecessor, the JBL Endurance Peak 3 True Wireless, instead.
The JBL Endurance Peak II have reasonable Bluetooth connectivity. They don't support NFC or multi-device pairing, which can be disappointing if you switch your audio source often. Their latency is likely too high to be suitable for watching videos or gaming. However, some apps compensate for latency, so your real-world experience may vary.
These headphones are Bluetooth-only.
These Bluetooth-only headphones can't be used with a wired connection. They come with a USB-C cable for charging their case.
