• JBL Vibe Flex True — biggest strength: open-ear design with signature deep bass, IP54 water/dust resistance and 32 hours total battery (8 + 24 in the case), so it stays comfortable and aware during workouts and city walks.
• JBL Vibe Flex True — biggest trade-off: no noise cancellation at all, and an open-ear shape means outside noise leaks in by design — that's the point, but it's not for blocking out a plane cabin.
• LORELEI QC60 — biggest strength: hybrid active noise cancellation plus a 60-hour battery and foldable over-ear comfort, built for travel and long desk sessions.
• LORELEI QC60 — biggest trade-off: it's a full-size over-ear headphone at 0.5 kg, so it's bulkier to carry and it seals you off from your surroundings rather than keeping you aware.
• Pick JBL Vibe Flex True if you want lightweight earbuds for running, cycling, commuting on foot, or any situation where hearing what's around you matters.
• Pick LORELEI QC60 if you want to silence engine drone, office chatter or a noisy room and wear one pair all day without recharging.
The Vibe Flex True is a pair of open-ear wireless earbuds, and the open-ear part is the whole story. Instead of plugging your ear canal, the earpiece sits outside it, so ambient sound comes through naturally. In my opinion that makes these the better pick for anyone who has ever felt uneasy wearing sealed earbuds while crossing a street, biking a trail or running near traffic. You get your music, but you also get the world.
On the sound side, JBL leans hard into its deep bass tuning. The drivers are dynamic, the frequency range runs 20Hz to 20,000Hz, and impedance sits at 16 ohm — low enough that a phone drives them easily. There's also a companion app where you can dial in your preferred sound, which is genuinely useful if you want more low-end thump or a flatter balance. The bass won't have the same chest-thump isolation as a sealed design simply because nothing is plugging your ears, but JBL's tuning is aimed squarely at punchy, energetic low frequencies.
Practical details matter here too. Battery is rated at up to 8 hours per charge with another 24 in the case, for 32 hours total. The earbuds carry IP54 water and dust resistance and the charging case is IPX2, so rain, sweat and splashes are fine. Bluetooth 5.3 lets you use either earbud alone or both together, and it supports streaming to multiple listeners. A dual-mic setup handles calls and voice assistant access.
Who should skip it? Anyone whose main goal is blocking noise. There's no ANC, no ambient-aware mode, no talk-through — none of that exists on this model. If your commute is a loud train or your office is an open floor plan, the open-ear design works against you.
The QC60 is a different animal entirely: a foldable, over-ear Bluetooth headphone built around hybrid active noise cancellation. The ear cups fully cover your ears with memory ear pads, and the hybrid system targets low and mid-frequency noise — the exact range where airplane engines, car engines and general commuting rumble live. If your goal is to make a noisy environment quiet, this is the design that does it.
Battery is the headline number: 60 hours of playtime on a single charge from an 800mAh battery. And if you somehow drain it, there's a 3.5mm stereo audio cable in the box so you can keep listening wired while it charges. That combination is rare and genuinely handy on a long trip.
Comfort engineering is clearly a priority. The protein ear pads rotate inward up to 100° and fold inward up to 120°, the headband is multi-level adjustable, and the whole thing folds down for packing. It's listed at 0.5 kg, which is on the heavier side for a headphone — worth knowing if you're sensitive to weight on your head over several hours, though the folding design and padded cups are aimed at making long sessions bearable.
Who should skip it? Anyone who wants something pocketable, or who needs to stay aware of their surroundings. Over-ear ANC headphones are the opposite philosophy from open-ear buds.
Side-by-Side: Which Should You Choose?
• Best for noise cancellation → LORELEI QC60. Hybrid ANC is its core feature; the JBL has none.
• Best for staying aware of your surroundings → JBL Vibe Flex True. The open-ear design lets ambient sound in on purpose.
• Best for battery life → LORELEI QC60. 60 hours versus 32 hours total on the JBL.
• Best for workouts and sweaty outdoor use → JBL Vibe Flex True. IP54 on the buds and IPX2 on the case; the QC60's sheet lists no water resistance rating.
• Best for long flights and travel → LORELEI QC60. ANC plus folding design plus a wired backup cable is a travel kit.
• Best for portability → JBL Vibe Flex True. Earbuds in a compact case versus a 0.5 kg over-ear headphone.
• Best for calls and voice assistant use → JBL Vibe Flex True. Dual mics with voice assistant support; the QC60 has a built-in mic but its sheet emphasizes noise cancellation and music.
• Best for all-day desk or office wear → LORELEI QC60. 60-hour battery and over-ear padding suit a full workday; the JBL's open design won't mask office noise.
My Verdict
Yes — JBL's tuning is explicitly built around deep, punchy bass, with dynamic drivers and a 20Hz–20,000Hz range, plus an app to adjust the sound. Because it's open-ear, the bass won't feel as sealed-in as an over-ear design, but the low-end emphasis is there.
Yes. It uses hybrid active noise cancellation with memory ear pads that fully cover the ears, aimed at low and mid-frequency noise like engines and commuting rumble.
The LORELEI QC60 lasts longer at 60 hours per charge. The JBL Vibe Flex True gives up to 8 hours per charge plus 24 more from the case, for 32 hours total.
Yes — it ships with a 3.5mm stereo audio cable, so you can plug in and keep listening when the battery is low.
