If you want a purpose-built workout headphone with a secure two-way fit and dust/water protection, choose JBL Endurance Run 3; if you need two pairs of simple, versatile wired earbuds for everyday listening across lots of devices, choose iKeloah 2.
• JBL Endurance Run 3 — biggest strength: A sport-first design. FlipHook lets you wear it in-ear or behind-the-ear, TwistLock keeps it planted during hard sessions, and the IP65 rating means sweat, dust and rain aren't a dealbreaker.
• JBL Endurance Run 3 — biggest trade-off: It's a single-pair, single-purpose buy. You get one set of buds tuned and shaped for movement, not a spare pair to leave at the office.
• iKeloah 2 — biggest strength: You get two pairs in one box, with a 3.5mm plug that works across phones, tablets, laptops, PCs, consoles and MP3/MP4 players, plus an in-line remote and mic.
• iKeloah 2 — biggest trade-off: No official water- or dust-resistance rating is listed, so I wouldn't treat it as a gym-and-rain headphone the way I would the JBL.
• Who each is for: Pick JBL Endurance Run 3 if your listening happens while you move. Pick iKeloah 2 if you want cheap, flexible everyday earbuds and a backup pair.
The Endurance Run 3 is built around one idea: staying in your ears while you punish them. The FlipHook design is genuinely unusual — you can wear these either seated in your ear canal or hooked behind the ear, and you switch based on what feels stable for you. That flexibility matters more than it sounds. Some people can't keep a standard bud seated during burpees; the behind-the-ear option fixes that.
Then there's TwistLock, which JBL describes as the mechanism that keeps the buds locked in place with proper ear sealing and no discomfort. I can't verify comfort for your specific ear shape, but the design intent is clear: soft silicone tips in three sizes (the box includes spare tips) plus a locking fit. If your current earbuds pop out mid-run, this is the category of headphone designed to solve that.
The durability story is the IP65 rating. That's dust-proof and water-resistant, which covers sweat, light rain and general grime. It's the single most important spec here for anyone training outdoors. Add the 8mm dynamic driver tuned for JBL's Pure Bass signature, and you get a low-end-forward sound meant to push tempo rather than reveal fine detail.
The practical stuff: an in-line one-button remote with a microphone for calls, a long-press to trigger Siri or Google Assistant, and magnetic buds that click together so the cable doesn't flail around your neck between sets. It's wired, using a 3.5mm jack, and weighs about 16.8g. No battery, no charging case, no pairing — plug in and go. Buy it if your workouts are the main event. Skip it if you want earbuds for desk work and Netflix marathons, or if your phone has no headphone jack and you don't want an adapter.
The iKeloah 2 is a different philosophy entirely: breadth over specialization, and two pairs instead of one. The listing is a 2-pack of white in-ear wired earbuds with a 3.5mm plug, a built-in microphone and an in-line volume/media remote.
The pitch is compatibility. The 3.5mm plug is described as internationally certified and rust-resistant, and the brand lists support for iPhones, iPads, iPods, Android phones, laptops, PCs, gaming consoles and MP3/MP4 players. Note the "Apple MFi Certified" claim in the title — treat that as the manufacturer's own statement about the plug, not an endorsement of anything else. The point for a buyer is simple: if a device has a 3.5mm port, these should work.
Inside, iKeloah points to a built-in DAC chip and metal-plated connectors, with the goal of avoiding buzzing, popping and poor-contact issues that plague cheap wired buds. The cable is TPE with an oxygen-free copper core, which the brand says improves conductivity and reduces signal distortion. I can't measure any of that, but the design choices are aimed at the right problems for budget wired audio.
The fit is a standard ergonomic in-ear shape with noise isolation — the seal blocks ambient sound passively, and the brand says long sessions shouldn't cause ear discomfort. The remote handles play/pause, track skipping, volume and calls. Impedance is 16 ohm, so it's easy to drive from a phone or laptop without a headphone amp.
Buy it if you want a couple of pairs to scatter between a bag, a desk and a car, or you need wired buds for older devices and consoles. Skip it if you're specifically shopping for a sweat-and-rain headphone — there's no IP rating listed, so I wouldn't rely on it for hard outdoor training.
• Best for intense workouts → JBL Endurance Run 3. TwistLock, FlipHook and IP65 are all there for movement.
• Best for sweat, dust and light rain → JBL Endurance Run 3. The IP65 rating is the deciding spec.
• Best for fit flexibility → JBL Endurance Run 3. In-ear or behind-the-ear, your call.
• Best for multiple devices and multiple people → iKeloah 2. The 3.5mm plug covers phones, tablets, laptops, PCs and consoles, and you get two pairs.
• Best for keeping a spare pair around → iKeloah 2. Two sets in the box means one can live in a bag permanently.
• Best for voice assistant access → JBL Endurance Run 3. A long press of the button wakes Siri or Google Assistant.
• Best for cable management between sets → JBL Endurance Run 3. The magnetic buds clip together around your neck.
• Best for the desk-and-commute crowd → iKeloah 2. Lighter, simpler, and the in-line volume control is handy for laptop use.
One thing neither sheet tells you is price, and that's where these two will likely diverge the most in your decision. Check the current price on Amazon for both before you commit — the gap is usually the tiebreaker when the feature sets are this different.
In my opinion, the JBL Endurance Run 3 is the better buy for anyone whose primary use is training. The IP65 rating, TwistLock retention and FlipHook two-way fit are concrete engineering answers to real workout problems, and no amount of compatibility breadth replaces a headphone that stays in your ear and survives sweat. I'd choose the iKeloah 2 only if my priority is having two cheap, flexible pairs for desks, bags and older devices — and I'd accept that they aren't built for hard, sweaty sessions. If you train regularly, buy the JBL.
FAQ
The brand states the 3.5mm plug works with iPhones, iPads, iPods, Android smartphones, laptops, PCs, consoles and MP3/MP4 players. Just confirm your device actually has a 3.5mm headphone jack, since many newer phones don't.
Both list sound isolation, and both are in-ear designs that rely on a physical seal. The JBL adds three sizes of ear tips in the box, which gives you a better chance of getting a proper seal — and a good seal is what actually blocks outside noise.
The iKeloah 2 is a 2-pack, so you receive two pairs of earbuds. The JBL Endurance Run 3 is a single pair, but it ships with an enhancer, three sizes of ear tips and a warranty card.
That depends on what you're buying for. If you want workout-specific features in one pair, JBL is the stronger value. If you want two usable pairs for everyday listening, iKeloah is. Check the current price on Amazon for both, since pricing shifts over time.
