How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a true-wireless sport earbud with deep bass, dual-ear independence and a familiar app-free Bluetooth experience for land workouts, choose JBL Endurance Peak II; if you need headphones that survive being fully submerged and play music without a phone at all, choose QMHL Swimming Headphones. That's the whole decision in one line. Everything below explains why those two paths split where they do.
• JBL Endurance Peak II — biggest strength: 30 hours of total playback (6 in the buds, 24 in the case), JBL Pure Bass tuning and an IPX7 sweatproof/waterproof build in a true-wireless ear-hook shape.
• JBL Endurance Peak II — biggest trade-off: No built-in memory and no on-board MP3 mode, so it always needs a connected Bluetooth device, and there's no active noise cancellation.
• QMHL Swimming Headphones — biggest strength: IP68 waterproofing rated for full submersion up to 2 meters, plus 32GB of built-in memory for roughly 8,000 songs so you can swim without carrying a phone.
• QMHL Swimming Headphones — biggest trade-off: Bone conduction means open-ear sound with no bass isolation, no noise cancellation, and it isn't a true-wireless design.
• Who each is for: JBL Endurance Peak II for gym, running and everyday Bluetooth listening; QMHL for lap swimming and phone-free water sessions.
The Endurance Peak II is built around one idea: keep the music going through a hard workout. JBL's Pure Bass tuning is the headline, and it's paired with a dynamic driver running a 20Hz–20,000Hz frequency range at 16 ohms. In practice that means a warm, bass-forward sound that's meant to push you through a set rather than deliver studio-flat accuracy.
The PowerHook design is the other half of the story. It's an ear-hook shape you adjust to your own ear, so the buds hang on rather than relying purely on a seal. That matters for running, lifting and anything bouncy. Dual Connect is the feature I'd point a frequent caller to — either earbud works independently for calls, volume and voice assistant, so you can pop one out and keep going. Touch controls handle media, and the whole thing is IPX7, which covers sweat and rain without drama.
On battery, you get 6 hours in the buds and 24 more in the case for 30 total. The case itself charges over USB-C, and the charge time is listed at 6 hours. The fit note is worth repeating because JBL calls it out directly: if the tips don't match your ear canals, sound quality and call performance suffer, so it's worth cycling through the three included tip sizes.
QMHL Swimming Headphones: Who It's For
The QMHL pair starts from a completely different premise. Its IP68 rating means it can be fully submerged to about 2 meters, which is the spec that separates it from almost every "waterproof" sport earbud. If your workout is in a pool, that's the feature that matters most.
The second pillar is the 32GB of built-in memory. That's room for roughly 8,000 songs stored on the headphones themselves, so you can swim, run or ride with no phone, no armband and no Bluetooth pairing at all. For lap swimmers who've been taping a phone into a waterproof pouch, this is the whole point.
Sound comes through bone conduction, not through your ear canal. The driver is a bone conduction type running 20Hz–20,000Hz at 8 ohms. Because nothing plugs your ears, you stay aware of traffic, other swimmers and your surroundings — a real safety advantage outdoors, and a real limitation in a noisy gym, since there's no noise cancellation and no bass seal. The frame is titanium with metal and plastic enclosure materials, and the controls are physical buttons rather than touch, which is easier to operate with wet hands.
Battery is listed at up to 10 hours of playback or talk time, with a quick-charge feature that gives you 2 hours of use from 15 minutes of charging; a full charge takes about 2 hours. Bluetooth 6.0 handles the wireless side when you do want it. The age range is listed as 8–120, and the package includes noise-cancelling earplugs, a cable and a user manual.
Who should buy it? Swimmers, surfers and anyone who wants phone-free audio in or near water. Who should skip it? Anyone who wants deep bass, isolation from a noisy environment, or the fully wireless feel of two independent buds.
Side-by-Side: Which Should You Choose?
• Best for phone-free listening → QMHL Swimming Headphones. 32GB of internal memory and no required pairing beats a Bluetooth-only design for pool or trail sessions.
• Best for bass and music energy → JBL Endurance Peak II. JBL Pure Bass with a 16-ohm dynamic driver is tuned for impact; bone conduction trades that punch for open-ear awareness.
• Best for total battery endurance → JBL Endurance Peak II. 30 hours combined (6 + 24 in the case) versus up to 10 hours on a single charge.
• Best for a fast top-up → QMHL Swimming Headphones. 15 minutes of charging returns 2 hours of playback, which is handy if you forget to charge the night before.
• Best for hands-free calls and voice assistants on either ear → JBL Endurance Peak II. Dual Connect lets either bud run the show independently.
• Best for staying aware of traffic and surroundings → QMHL Swimming Headphones. Open-ear bone conduction keeps your ears uncovered by design.
• Best for touch controls and a fully wireless fit → JBL Endurance Peak II. Touch control and a true-wireless ear-hook shape suit gym and road work.
If I had to pick one, it comes down to where you sweat. In my opinion, the JBL Endurance Peak II is the better buy for the majority of people, because most workouts happen on land and the 30-hour combined battery, Pure Bass tuning and true-wireless ear-hook design cover gym, running and commuting in one package. But if you actually swim, my recommendation flips hard to the QMHL Swimming Headphones — IP68 submersion and 32GB of built-in memory solve a problem the JBL simply isn't designed for. Buy for your environment, not for the spec sheet.
No. It carries an IPX7 rating, which JBL frames around sweat and rain. The QMHL pair is rated IP68 and explicitly designed to be submerged to about 2 meters, which is the rating you want for pool use.
Yes. They include 32GB of built-in memory — roughly 8,000 songs — so you can load your music and swim or run with no phone and no Bluetooth connection at all.
The JBL Endurance Peak II wins on total runtime with 6 hours in the buds plus 24 in the case. The QMHL gives up to 10 hours per charge but adds a quick-charge feature that returns 2 hours of playback in 15 minutes.
The JBL. Its Pure Bass tuning and 16-ohm dynamic driver are built for low-end impact. Bone conduction in the QMHL keeps your ears open, which is great for safety but doesn't deliver the same bass weight. As for what either costs today, check the current price on Amazon before you commit.
