About the JBL Endurance PEAK

I can't stress how much I appreciate truly wireless earbuds during workouts — there's no cable to get in your way or to get caught on gym equipment. And the sweat-proof JBL Endurance PEAK earbuds are designed to fit securely and comfortably while you move. Music plays wirelessly from your phone via Bluetooth.

Value-packed, 100% wire-free workout 'phones

I can't stress how much I appreciate truly wireless earbuds during workouts — there's no cable to get in your way or to get caught on gym equipment. And the sweat-proof JBL Endurance PEAK earbuds are designed to fit securely and comfortably while you move. Music plays wirelessly from your phone via Bluetooth.

An around-the-ear hook stablizes each earbud, while JBL's patented TwistLock® system secures them in your ear. You put each earpiece in and twist. You'll spend more time working out and less time having to adjust your headphones. 

Strong sound for motivational music

JBL has fine-tuned their sound signature to please the most amount of people — from their so-called "entry-level" headphones on up. We've visited their parent company, Harmon, and you wouldn't believe the amount of research that goes into honing their acoustics.

I haven't heard these particular earbuds, but as a whole, JBL headphones deliver a satisfying, mids-focused sound. They tune their headphones to deliver clear vocals and hard-hitting bass. Those are two sound traits that can really help push you to run or exercise just a little bit more.    

Extra-soft and sweat-proof to survive the toughest training

JBL's specially made ear tips feel soft and comfortable for your entire workout — no matter how long you go. You get three different-sized flexible silicone 'buds, so you can find the right fit. They're designed to avoid nerves and pressure points inside the ear that cause pain or discomfort.

And these earbuds can handle sweat and rain — in fact, they're IPX7-rated waterproof. So you can keep the music going when you're hitting a grueling trail outdoors.

A carrying case that recharges your earbuds wirelessly

The JBL Endurance PEAK earbuds offer up to four hours of on-the-go music listening on a full charge. When it's time to refuel, you just click them into the included charging carrying case. This pocket-sized case can bank up to 24 hours of power to recharge your earbuds. 10 minutes inside the case gives you an hour of wireless use.

Product Research


Overview: The JBL Endurance PEAK ear buds are truly wireless in-ear headphones with no connecting cables. Each ear bud has a built-in rechargeable battery, plus touch controls for power, music playback, and phone calls. The Endurance PEAK ear buds come with three pairs of silicone ear tips, a pair of enhancers to provide an optimum airtight seal, and a hard, clam-shell charging case.

Drivers: The JBL Endurance PEAK ear buds are equipped with 10mm dynamic drivers that deliver the JBL Signature Sound with a wide frequency range of 16Hz-22kHz.

Water Resistant: The Endurance PEAK ear buds are IPX7-certified to protect the internal components from water and sweat. This splashproof design keeps them performing in the rain or during a workout.

Bluetooth: The ear buds connect to your smartphone or tablet via Bluetooth 4.2 (2.402-2.480 GHz). The ear buds support A2DP (V1.3), AVRCP (V1.5), and HFP (V1.6).

PowerHook/TwistLock: The Endurance PEAK ear buds have a flexible and secure ear hook design that keeps them in your ears even during rigorous activity. When the end of the right ear hook is pulled out of its resting position, the ear bud automatically powers on and goes into pairing mode. The ear hooks feature TwistLock technology for extra comfort and stability when wearing. When inserting the ear buds, twisting them backward helps to securely lock them in place.

LED Indicators: Each ear bud has an LED to indicate the charging and pairing status. In addition, there are four LEDs on the charging case to show the charging status in 25% increments (4 LEDs-100% charged, 1 LED-<25% charged).

Mono Call Mode: When you answer a phone call, the JBL Endurance PEAK will automatically switch from stereo to mono mode on the right ear piece for a more natural-sounding phone call. When the call ends, the ear buds automatically switch back to stereo mode.

Touch Controls: The JBL Endurance PEAK features intuitive touch controls on the right ear bud that lets you play/pause, change tracks, take calls, mono/stereo modes, and control volume.

Ear Tips: The ear buds comes with three pairs (S, M, and L) of silicone rubber ear tips, ensuring you get an airtight fit regardless of the shape or size of your ear. In addition, a pair of ergonomic "enhancers" are included to give you a more secure fit for rigorous activities.

Rechargeable Batteries: Each of the JBL Endurance PEAK ear buds contains a 3.7-volt 75mAh Lithium-Ion rechargeable battery. The charging case contains its own 3.7-volt 1500 mAh rechargeable battery for over 24 hours of total backup charge. Fully charged ear buds provide up to 4 hours playback time. The ear buds charge in the case in less than two hours. A 10-minute quick charge will give you approximately 1 hour of playback time. The ear buds charge in the provided case with the supplied Micro USB cable.

Customer Q&A

5 questions already asked

can they be worn comfortably with glasses?
[ Kevin  Apr 27, 2020 ]
6 answers
yes i put the ear buds in, then put my glasses on
[ michael  Apr 29, 2020 ]  Staff
Yes, I wear them 6 hours a day with thick safety glasses and a hard hat on and they are still very comfortable after a year.
[ CHRISTIAN  Apr 28, 2020 ]  Staff
They do go over the ear, so I would imagine they would not be ideal.
[ Robert  Apr 28, 2020 ]  Staff
Comfort is really subjective. However, I have no complaints wearing them with my glasses.
[ NICHOLAS  Apr 27, 2020 ]  Staff
Not sure because my husband never wore these with his glasses, and we ended up returning for a pair of Bose in-ear headphones. But, if for some reason you get these and they don't work out with wear with your glasses, Crutchfield has amazing customer service and a easy, hassle free return/exchange program!
[ Jennifer  Apr 27, 2020 ]  Staff
Not really as the temple area (the part that wraps around the ear) is a little stiff. I wear glasses and have to take them off in order to use this product. I like the product overall as it remains on your head as you exercise and wish the temples were a little softer for people who wear glasses.
[ ROBERT D  Apr 27, 2020 ]  Staff
Can these headphones be used with a computer (SKYPE) for meeting or telephone communications?
[ Glenn  Jan 14, 2020 ]
1 answer
They operate via Bluetooth, so any device that has BT will be able to pair with these.

They should. They paired fine/easy to my iPhone. Crutchfield has an awesome, easy, 60 day return policy in case they don't for some reason. If you're considering these to use for music, I'd recommend Bose's earbuds instead. The sound quality is much richer with bose. You really hear the highs, lows, and depth of base in Bose; missing in the JBL in my opinion.
[ Jennifer  Aug 28, 2019 ]  Staff
Yes they will, I use them every day with my watch
[ martin  Aug 27, 2019 ]  Staff
I don't know. Did you call Crutchfield? They should be able to provide the answer.
[ NICHOLAS  Aug 27, 2019 ]  Staff
Are they made of rubber? I have a rubber allergy
[ Pause  Jun 25, 2019 ]
1 answer
Hi Pause, thanks for your question! The JBL Endurance Peak wireless earbuds are made of silicone.
[ Jess  Jul 02, 2019 ]  Staff
Can i use just one ear piece?
[ Will  Mar 15, 2019 ]
2 answers
Yes, just leave the other one off. You can't though only turn one on and not the other.
[ Jennifer  Aug 28, 2019 ]  Staff
As long as its the right one you are willing to use, then yes! That can work My Bio:
