How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a playful, colourful on-ear headphone you can wear all day and still hear the room around you, choose Riwbox WT-7S; if you need to switch off aeroplane engines, traffic and open-plan chatter with proper active noise cancelling, choose BYDGUMEI L90.
• Riwbox WT-7S — biggest strength: a genuinely huge 60-hour playtime off a one-hour charge, plus LED lights on both earcups that pulse with your music and can be switched off to stretch the battery further.
• Riwbox WT-7S — biggest trade-off: it uses sound isolation only, so it muffles noise passively but does not cancel it, and the on-ear design presses against the ear rather than sitting around it.
• BYDGUMEI L90 — biggest strength: hybrid active noise cancellation that the spec sheet says filters up to 90% of low-frequency ambient sound, with three selectable modes for traffic, outdoor and indoor environments.
• BYDGUMEI L90 — biggest trade-off: the battery figures are quoted in ANC mode rather than a single always-on number, and ANC does not work when you switch to the AUX cable.
• Who the Riwbox WT-7S is for: students, kids and teenagers who want a fun, lightweight, foldable headset for PC, tablet, TV and travel.
• Who the BYDGUMEI L90 is for: commuters, office workers and long-haul travellers who want quiet, memory foam comfort and USB-C charging.
The WT-7S is built around personality first, practicality second — and that is not a criticism, it is the whole point of the product. Both earcups carry LEDs that flash up and down in time with whatever you are playing, which is why the spec sheet lists students, kids and teenagers as the target buyer and calls it a good gift for family. If you want a headphone that looks like a piece of kit rather than a black slab, this is the one.
Underneath the lights it is a sensible everyday wireless headset. Bluetooth 5.3 handles the pairing and remembers your device afterwards, so you are not re-pairing every morning. The 40mm dynamic drivers, 32-ohm impedance and 20 Hz–20 kHz frequency response are mainstream numbers — good for pop, podcasts, YouTube and gaming audio, not aimed at critical listening. There is a 3.5mm jack and a cable included, so when the battery eventually runs dry you can keep going wired. Volume, track skipping and call handling run through push buttons on the earcups, and the built-in microphone covers calls and online classes.
The battery is the quiet headline: 60 hours of average life from roughly one hour of charging, and you can turn the LED effect off in Bluetooth mode to keep more of that for music. At 6.4 ounces it is light enough for a school day, and it folds for a backpack.
BYDGUMEI L90: Who It's For
The L90 is the opposite philosophy: it exists to make the world quieter. It uses hybrid active noise cancellation with dual noise-detection microphones, and the manufacturer states it filters out up to 90% of low-frequency ambient sound. You also get three selectable ANC modes — traffic, outdoor and indoor — which is more granularity than most buyers expect at this level. That makes it a natural fit for trains, planes, buses and noisy offices.
Comfort is the second pillar. These are over-ear headphones with oval earcups filled with memory foam, so they surround the ear instead of pressing on it, and the lightweight structure is explicitly pitched at long meetings. Controls are touch-based on the earcup rather than physical buttons, and AI call handling is part of the feature set. Charging is USB-C, and the box includes an AUX cable, a travel pouch and a USB-C cable.
Audio is handled by a 40mm rubidium iron boron dynamic driver with a silk diaphragm, quoted as reproducing punchy bass and crisp treble and extending up to 40kHz for clarity — a high-resolution framing rather than a bass-heavy one. Impedance is 16 ohms, which generally means it is easy to drive from a phone or laptop. Battery life is quoted as up to 50 hours in noise-cancelling mode, and a short charge is said to give several hours of listening, which is genuinely useful if you forgot to plug it in the night before.
Side-by-Side: Which Should You Choose?
• Best for battery life → Riwbox WT-7S. A quoted 60 hours on a one-hour charge, and you can disable the LEDs to squeeze out more.
• Best for noise cancelling → BYDGUMEI L90. Hybrid ANC with three modes and a claim of up to 90% low-frequency reduction; the Riwbox offers passive isolation only.
• Best for long-wear comfort → BYDGUMEI L90. Over-ear memory foam cups distribute pressure better than on-ear pads over a full working day.
• Best for kids, teens and gifting → Riwbox WT-7S. The flashing LEDs, pink finish, folding design and light 6.4-ounce build are squarely aimed at younger users.
• Best for flights and commuting → BYDGUMEI L90. This is exactly the scenario ANC was invented for, and the included travel pouch fits the use case.
• Best for desktop and TV use → Riwbox WT-7S. The 3.5mm jack and included cable make it easy to plug into a PC, tablet or TV without re-pairing.
• Best for phone-driven listening → BYDGUMEI L90. Touch controls and a 16-ohm impedance make it straightforward to drive from a handset.
• Best for wired-only listening → Riwbox WT-7S. The L90 loses ANC over AUX, so if you plan to stay wired, the Riwbox gives you more of what you paid for.
In my opinion, the BYDGUMEI L90 is the better buy for most adults. Active noise cancelling with three modes, over-ear memory foam comfort, USB-C charging and a high-resolution 40mm driver cover the situations where headphones actually earn their keep — commuting, flying and concentrating at a desk.
I would only steer you to the Riwbox WT-7S if the person wearing them is a kid or teenager, or if you specifically want the LED light show, the lighter on-ear fit and the longer quoted battery. It is a fun headphone, and it does its job well — it just is not trying to silence the world. Check the current price on Amazon for both before deciding, since that is the one variable that can flip this call.
FAQ
Riwbox quotes around 60 hours of average battery life from roughly a one-hour charge. BYDGUMEI quotes up to 50 hours with noise cancelling on. Both are long enough that charging becomes a weekly rather than daily chore.
Both include a 3.5mm cable and jack. On the Riwbox WT-7S, wired mode is simply a way to keep listening when the battery runs out. On the BYDGUMEI L90, note that ANC and AUX connections are not compatible, so you lose noise cancelling when wired.
The BYDGUMEI L90 is the over-ear option with memory foam earcups and a design explicitly aimed at long meetings, so I would pick it for extended wear. The Riwbox WT-7S is lighter at 6.4 ounces but sits on the ear, which some people find less comfortable after a few hours.
