How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a cheap, no-fuss replacement cord to bring a pair of Beats by Dr. Dre headphones back to life, choose EARLA TEC Replacement Audio Cable; if you need a purpose-built wired sport headphone for running and gym sessions, choose JBL Endurance Run 3. They look similar on paper — both are wired, both have a 3.5mm plug, both have an in-line mic — but they exist for completely different jobs, and picking the wrong one will leave you disappointed.
• EARLA TEC Replacement Audio Cable — biggest strength: it's a repair part, not a new headphone. Two male 3.5mm plugs (one straight, one L-shaped) and a 1.4m TPU-coated cord let you revive Beats Solo/Studio/Pro/Detox/Mixr/Executive/Pill models instead of replacing them.
• EARLA TEC Replacement Audio Cable — biggest trade-off: the in-line remote only works on Apple iPod, iPad and iPhone. On Samsung or other non-Apple devices you get audio and the mic, but not the volume/track buttons.
• JBL Endurance Run 3 — biggest strength: it's built for movement. FlipHook lets you wear it in-ear or behind-the-ear, TwistLock claims a secure, non-painful fit, and the IP65 rating handles dust and sweat.
• JBL Endurance Run 3 — biggest trade-off: it's a complete headphone at 8 ohms with 8mm drivers, so it's tuned for bass-forward workout listening rather than neutral, critical listening — and the single-button remote is simpler than a full three-button control.
• Who each pick is for: EARLA TEC for anyone who already owns Beats headphones with a dead or damaged cable; JBL Endurance Run 3 for anyone who needs a fresh, sweat-resistant pair for training.
This is a spare part, and that's the whole point. If your Beats by Dr. Dre Solo, Studio, Pro, Detox, Mixr, Executive or Pill headphones still sound fine but the cable has frayed, crackled or lost a channel, this cord is the cheapest way back to a working setup. It ships with two male 3.5mm plugs — one straight, one L-shaped — which matters because the angled plug is the one that survives being jammed into a phone in your pocket, while the straight end seats properly in the headphone cup.
The cable itself is 1.4m and TPU-coated, which the spec sheet describes as soft, tangle-free and durable. In practice, that's the sensible material choice for something that lives coiled in a bag: TPU has a rubbery give that resists the stiffening and cracking you get from cheap PVC cords. The grey round finish is understated and won't clash with most Beats colorways.
Buy it if: you own Beats headphones with a dead cable and you're mostly on an iPhone or iPad. Skip it if: you're on Android and expect the remote to work, or if you actually need new headphones rather than a repair.
JBL Endurance Run 3: Who It's For
This is a finished product, and it's clearly designed around one scenario: moving. FlipHook is the headline feature — a flexible two-way design that lets you wear the buds either in-ear or hooked behind the ear. That's genuinely useful, because behind-the-ear routing is what keeps a cable from whipping around when you're sprinting or jumping rope, while in-ear is what you want for a commute or a desk session. One pair, two very different wearing styles.
Then there's TwistLock, which JBL describes as the combination of soft ear tips and ergonomic shaping that keeps the buds sealed and stable without hurting. You get three sizes of ear tips plus an enhancer in the box, so there's some room to dial in the fit. The housing uses silicone or similar soft material, and the whole thing weighs 16.8g — light enough that it shouldn't tug during a run.
The IP65 rating is the spec I'd point to first for anyone training outdoors. IP65 means dust-tight and protected against water jets, so sweat, rain and the general grime of a gym bag are all within its comfort zone. That's a meaningful difference from a bare replacement cable, which has no such protection and isn't meant to be soaked.
Sound-wise, JBL Pure Bass comes from a single 8mm dynamic driver with 8-ohm impedance and a 20Hz–20,000Hz range. Eight ohms is very low, which means these are easy to drive from a phone — you'll get volume without pushing the source hard. The tuning is bass-forward by design, which suits high-tempo playlists and podcasts you want to feel rather than analyze.
Controls are deliberately minimal: one in-line button with a microphone for calls, and a long press summons your phone's native voice assistant (Google Assistant or Siri). Magnetic buds snap together for cable management around your neck when you're between sets.
Buy it if: you want a dedicated wired sport headphone that stays put, shrugs off sweat and doesn't need charging. Skip it if: you want multi-button track and volume control on the cable, or you're after a flat, analytical sound.
• Best for repairing existing Beats headphones → EARLA TEC Replacement Audio Cable. It exists only to replace a broken cord on Solo, Studio, Pro, Detox, Mixr, Executive and Pill models.
• Best for working out → JBL Endurance Run 3. IP65 dust and water resistance plus TwistLock and FlipHook are built for sweat and movement.
• Best for iPhone users who want cable controls → EARLA TEC Replacement Audio Cable. Volume, track skipping and Siri activation all work on Apple devices.
• Best for Android users → JBL Endurance Run 3. Its single-button remote and voice assistant support aren't locked to Apple hardware the way the EARLA TEC remote is.
• Best cable management → JBL Endurance Run 3. Magnetic buds clip together around your neck; the EARLA TEC cord relies on its tangle-free TPU coating alone.
• Best for a hands-free call on the go → either, with caveats. Both have an in-line mic, but EARLA TEC's button set is richer on Apple devices while JBL's is one-button simple everywhere.
• Best if you need new headphones, full stop → JBL Endurance Run 3. The EARLA TEC cable is useless without a pair of Beats to plug it into.
• Best for sound you can feel → JBL Endurance Run 3. The 8mm dynamic driver and Pure Bass tuning are aimed at bass-forward listening.
My Verdict
The cable's audio and microphone work with non-Apple devices, including Samsung Galaxy models. However, the in-line remote buttons — volume, track skipping and voice assistant — only function on Apple iPod, iPad and iPhone.
Yes. It carries an IP65 rating, which means it's dust-tight and resistant to water jets, so rain and heavy sweat are within its design limits. Just don't submerge it.
They're not really comparable — the EARLA TEC cable has no drivers of its own and simply passes through whatever your Beats headphones produce. The JBL Endurance Run 3 has its own 8mm dynamic driver tuned for JBL Pure Bass, so it delivers a bass-forward signature on its own.
It depends on what you already own. If you have working Beats headphones with a dead cable, the EARLA TEC cord is the cheaper fix. If you need a full set of sport headphones, the JBL Endurance Run 3 does more for the money. Check the current price on Amazon for each before deciding.
