How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a pair of earbuds that stay locked in your ears through sweat, rain and heavy lifting, choose Redzoo Headphones V5.0; if you need over-ear headphones with active noise cancellation, a huge 48-hour battery and Hi-Res audio for long listening sessions, choose Wentronic Y01.
• Redzoo's biggest strength: a sport-first design — in-ear ear-hook fit, IPX7 waterproofing and 16 hours of playtime make it a natural gym companion.
• Redzoo's biggest trade-off: it's an in-ear earbud with no active noise cancellation, so it won't isolate you from a noisy commute the way an over-ear ANC pair will.
• Wentronic Y01's biggest strength: active noise cancellation, a 40mm dynamic driver with a 20Hz–40kHz range and up to 48 hours of playback in a foldable over-ear shell.
• Wentronic Y01's biggest trade-off: over-ear headphones are bulkier and warmer to wear, and they aren't built around a secure sport fit or water-resistance rating.
• Pick Redzoo if your priority is a stable, sweat-proof fit for running, gym work and outdoor training.
• Pick Wentronic Y01 if your priority is immersive, noise-cancelled listening at a desk, on a plane or during long work sessions.
The Redzoo Headphones V5.0 (model "Flame") is built around one idea: staying put while you move. The in-ear, ear-hook design with a rounded tip is meant to hold its position during strenuous activity, and it ships with four eartip sizes (XS, S, M, L) so you can dial in a proper seal. That seal matters — a good fit is what lets the 11mm dynamic driver deliver the "Bass+" sound the design is aiming for, and it also helps with passive isolation when you're training.
On the technical side, you get Bluetooth 5.0 with a quoted 10-metre range, SBC and AAC audio support, and multipoint pairing so you can stay connected to two devices at once. The CVC6.0 microphones are there for voice calls, and the media controls are push-button. Battery life is quoted at up to 16 hours of music or talk time from a 2-hour charge, and the headphones report their remaining battery level on your phone's screen — a small detail that's genuinely useful mid-workout.
The standout spec for its intended use is IPX7. That's a waterproof rating, not just "sweat-resistant," and combined with an internal nano-coating it's designed to shrug off sweat, heavy rain and all-weather training. It's also worth noting the practical stuff: a 2-year warranty, a lightweight 0.11 kg build, and a note from the brand that packaging has changed, so you may receive either the older red box or the newer blue one — same product either way.
Wentronic Y01: Who It's For
The Wentronic Y01 is the opposite philosophy: comfort and immersion over athletic grip. It's an over-ear headphone with oval, leather-covered earpads and a foldable frame, finished in pink. The 40mm dynamic driver covers a 20Hz–40kHz frequency range — a notably wide figure that's the basis for the Hi-Res audio claim — so this is a pair aimed at people who care about how music and detail sound, not just whether it stays in during a sprint.
The headline feature is active noise cancellation. Unlike passive isolation, ANC actively reduces the noise around you, which is exactly what you want on a plane, a bus or in a shared office. Battery life is quoted at up to 48 hours from a 2-hour charge — three times the Redzoo's figure — which makes it a realistic choice for a multi-day trip without hunting for a charger. Bluetooth 5.3 handles the wireless side, and dual-device pairing is supported, so you can hop between a laptop and a phone.
One genuinely useful extra: it has a 3.5mm jack and ships with a 3.5mm audio cord. That means you can run it wired when the battery is flat or when a device has no Bluetooth — something the Redzoo can't do, since it has no jack at all. In the box you get the headphones, the audio cord, a charging cable and a manual. Warranty is 1 year.
Who should buy it: commuters, remote workers, students, travellers and anyone who wants a comfortable over-ear fit with noise cancellation for hours at a time. Who should skip it: if you train hard and sweat heavily, an over-ear leather-padded headphone isn't the right shape or material — there's no water-resistance rating here, and it will feel warm and bulky during a workout.
• Best for workouts and running → Redzoo Headphones V5.0. The ear-hook in-ear fit plus IPX7 waterproofing is purpose-built for movement and moisture.
• Best for noise cancellation → Wentronic Y01. Active Noise Cancellation is a feature the Redzoo simply doesn't have.
• Best for battery life → Wentronic Y01. Up to 48 hours versus up to 16 hours.
• Best for long-haul travel → Wentronic Y01. ANC plus 48 hours plus a foldable frame is a travel-friendly combination.
• Best for all-weather outdoor use → Redzoo Headphones V5.0. IPX7 and nano-coating versus no stated water resistance on the Y01.
• Best for wired fallback → Wentronic Y01. It has a 3.5mm jack and includes an audio cord; the Redzoo is wireless-only.
• Best for audio detail on paper → Wentronic Y01. A 40mm driver with a 20Hz–40kHz range reaches further than the Redzoo's 20Hz–20,000Hz.
• Best for a discreet, lightweight carry → Redzoo Headphones V5.0. At 0.11 kg in an in-ear format, it disappears into a pocket.

In my opinion, these two aren't really competitors — they're answers to different questions. If I trained regularly and wanted one pair that could survive sweat, rain and a heavy gym session without shifting, I'd buy the Redzoo Headphones V5.0. Its IPX7 rating and ear-hook fit are the exact things that matter when you're moving, and the 2-year warranty is a nice reassurance. But if my listening happens at a desk, on a commute or on a plane, I'd take the Wentronic Y01 without hesitation: active noise cancellation, 48 hours of battery, a wider frequency range and a wired option make it the more versatile everyday headphone. Decide which of those two lives is yours, and the choice makes itself.
how to headphones work
Both of these are wireless Bluetooth headphones, so they work the same way in principle: an internal amplifier drives a dynamic driver that turns electrical signals into sound. The Redzoo uses an 11mm dynamic driver over a 20Hz–20,000Hz range, while the Wentronic Y01 uses a 40mm dynamic driver over a wider 20Hz–40kHz range. The Y01 also works passively over a 3.5mm cable, whereas the Redzoo is Bluetooth-only.
how to headphones on iphone
Pairing either model with an iPhone is a standard Bluetooth process: put the headphones into pairing mode and select them from the Bluetooth menu in Settings. Both use Bluetooth — version 5.0 on the Redzoo and 5.3 on the Wentronic Y01 — and both support connecting to two devices, so you can keep a phone and a laptop linked at the same time. The Redzoo also reports its battery level on your phone's screen.
how to headphone mode off
If you mean turning off active noise cancellation, that only applies to the Wentronic Y01, which has an ANC mode you can switch off via its button controls when you want to hear your surroundings. The Redzoo has no noise-cancelling mode at all — it relies on the physical seal of its in-ear tips for passive isolation, so there's nothing to toggle.
how to headphones
If you're asking how to choose between them, match the headphones to the job. Pick the Redzoo for sport, sweat and weather thanks to its IPX7 rating and secure ear-hook fit. Pick the Wentronic Y01 for quiet, comfort and endurance listening thanks to its active noise cancellation and up to 48-hour battery. Check the current price on Amazon for both before deciding.
