How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a rugged, fully waterproof pair of in-ear sports buds with active noise cancelling and app control for teens, choose JBL Endurance Race 2; if you need an over-ear hook design with the newest Bluetooth, a bigger driver and longer charging range, choose PEFUPEW Earbuds. Both are built for movement, but they solve the same problem in very different ways — and for teens bouncing between gym class, running and gaming sessions, that difference matters more than any spec sheet headline.
• JBL Endurance Race 2 — biggest strength: IP68 waterproof and dustproof earbuds with a wing-enhancer and Twistlock fit, plus Active Noise Cancelling and Smart Ambient awareness. Biggest trade-off: the charging case is only IPX2 water-resistant, so you must dry the buds before docking them, and there's no over-ear hook.
• PEFUPEW Earbuds — biggest strength: an over-ear hook shape that spreads pressure off the ear canal, a larger 14.2mm driver for deeper bass, four ENC mics and Bluetooth 5.4. Biggest trade-off: passive noise isolation only — no active noise cancelling.
• Choose JBL Endurance Race 2 if you want true in-ear stability, real noise cancelling and a companion app for tuning how much of the world you hear.
• Choose PEFUPEW Earbuds if you prefer a hook-style fit, want the longest wireless reach and the newest Bluetooth generation, and don't need app control.
The Endurance Race 2 is the more "engineered" sports bud of the two. Its headline is the IP68 rating, which means it's fully dustproof and can survive being submerged deeper than a meter in both fresh water and sea water. That's a genuinely unusual level of protection for a true wireless earbud, and it's the reason I'd point a sweaty, rain-soaked runner or a swim-adjacent athlete toward it. The charging case is a different story: it's only IPX2 water-resistant, and JBL is explicit that you should dry the buds and the case before charging. That's a real ownership habit you have to build, not a marketing footnote.
The fit story is the second reason to pick it. JBL uses an ergonomic wing enhancer with Twistlock technology, which twists into the ear for a better seal and more stability, and JBL ships two enhancers plus three sizes of ear tips in the box. For anyone who has ever had a bud pop out mid-sprint, that's the whole point. Battery is quoted at 12 hours per charge with another 36 hours in the case for 48 total — with ANC off — and 10 minutes on the included USB-C cable gets you roughly four hours back. JBL explicitly recommends using only the included cable, which is worth respecting if you care about longevity.
Where it pulls ahead for a lot of buyers is the feature set around awareness. Active Noise Cancelling filters out distracting noise, and Smart Ambient lets you dial in how much of the outside world you hear — useful when you're crossing a street or want to hear a coach. Everything is touch-controlled and there's an app for further control. Bluetooth 5.3 with a 10-meter range is current and reliable, if not the newest standard.
PEFUPEW Earbuds: Who It's For
The PEFUPEW C605 takes the opposite approach: instead of cramming stability into the ear canal, it hangs the bud on a flexible, soft ear hook that sits over the ear. The brand's own framing is that this reduces ear canal pressure and suits long-term wear without discomfort. That's the single most persuasive argument for this pair. If in-ear buds make your ears ache after 30 minutes, the hook design is a structural fix, not a tuning tweak.
On paper it also wins the connectivity race. It runs Bluetooth 5.4, which the brand claims increases connection speed substantially over the previous generation, with a quoted audio transmission delay of just 40 milliseconds and a 15-meter range. That low-latency figure is the interesting one for teens, because it's the kind of number that actually matters when audio and video need to stay in sync — streaming, mobile play and casual gaming all benefit from a tighter delay. It won't replace a dedicated low-latency gaming headset, but for a pair of sport buds it's a thoughtful inclusion.
Audio hardware is bigger here too: a 14.2mm dynamic driver versus the much smaller 6.8mm unit in the JBL, with a three-layer composite diaphragm the brand says boosts bass and reduces distortion. Four ENC microphones are used to cut background noise on calls — that's call clarity, not music noise cancelling. And that distinction is important: the PEFUPEW uses passive noise cancellation and sound isolation, so it blocks sound by sealing your ear, with no active circuitry. Battery is quoted at 48 hours total, with up to 8 hours per bud at 50% volume and 4–5 extra charges in the case, plus USB-C fast charging and a dual LED display that shows remaining charge.
Who should buy it: hook-style fans, people with sensitive ear canals, teens who want the newest Bluetooth and a low-latency connection for streaming and casual gaming, and anyone who wants to glance at a case and see the battery level. Who should skip it: commuters who genuinely want active noise cancelling, and anyone who prefers a compact in-ear bud without a hook.
• Best waterproofing and dust protection → JBL Endurance Race 2. IP68 on the buds is a genuinely tough rating; the PEFUPEW's IP7 covers sweat and rain but not submersion.
• Best fit for sensitive or ache-prone ears → PEFUPEW Earbuds. The over-ear hook takes pressure off the ear canal, which is its core design argument.
• Best noise control → JBL Endurance Race 2. Active Noise Cancelling plus Smart Ambient awareness beats passive isolation for commuting, gyms and busy streets.
• Best connectivity and latency → PEFUPEW Earbuds. Bluetooth 5.4, a 15-meter range and a quoted 40ms delay make it the more future-proof link.
• Biggest driver and bass hardware → PEFUPEW Earbuds. A 14.2mm dynamic driver against 6.8mm in the JBL — a meaningful size gap on paper.
• Best for calls in noisy places → PEFUPEW Earbuds. Four ENC microphones are dedicated to voice pickup, versus JBL's general "crystal clear calls" positioning.
• Best charging convenience → PEFUPEW Earbuds. A 1.5-hour charge time and a dual LED case display versus JBL's 2-hour charge and no display.
• Best app control and tuning → JBL Endurance Race 2. Touch control plus an app gives you more ways to shape how the buds behave.
If you're shopping for a teen who wants one pair to cover workouts, school commutes and the odd gaming session, the honest split is this: the JBL is the more protective and more feature-rich athletic tool, while the PEFUPEW is the more comfortable, more connected all-rounder. Note that neither is marketed as a gaming headset, so if gaming is the primary use, treat the PEFUPEW's low latency as a bonus rather than a substitute for a dedicated set.
In my opinion, I'd buy the JBL Endurance Race 2 for a teen who actually trains — the IP68 rating, the Twistlock wing fit, the 48-hour total battery and the combination of Active Noise Cancelling with Smart Ambient awareness make it the more complete sports headphone, and the awareness modes are a real safety plus for anyone running outdoors. I'd choose the PEFUPEW Earbuds instead if comfort is the deciding factor, if ear-canal pressure has been a problem before, or if you want the newest Bluetooth and a low-latency connection for streaming and casual gaming. The one thing I'd flag to any buyer: check the current price on Amazon before deciding, because that's the variable that most often flips this call.
FAQ
How to use sports headphones
How to wear running headphones
Hook-style buds like the PEFUPEW Earbuds loop over the ear and rest outside the canal, which the brand says reduces ear canal pressure. In-ear designs like the JBL Endurance Race 2 rely on a wing enhancer and ear tips in three sizes to lock into the ear — pick the tip size that gives you a firm seal without discomfort.
How to pair jlab sport headphones
I can't speak to JLab here — this comparison covers JBL and PEFUPEW. For the PEFUPEW Earbuds, the brand states they automatically connect after being taken out of the charging case, so enable Bluetooth on your phone first. For the JBL Endurance Race 2, use Bluetooth 5.3 pairing within its 10-meter range.
How to charge impact sport headphones
Both pairs charge over USB-C. The PEFUPEW Earbuds quote a 1.5-hour charge time with a dual LED display showing remaining battery, while the JBL Endurance Race 2 takes about 2 hours and gives roughly four hours of playback from a 10-minute top-up — and JBL recommends using only the included cable.
