How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want all-day ANC earbuds with a six-mic ENC setup for calls and a 60-hour charging case, choose TOZO NC9; if you need an over-ear headset with 40mm drivers, a retro look, wired backup and up to 200 hours of standby, choose ROEL-PLAY Over Ear.
• TOZO NC9 — biggest strength: Hybrid active noise cancellation rated to a maximum 45dB reduction depth, six microphones with ENC for calls, and a charging case that shows remaining battery.
• TOZO NC9 — biggest trade-off: It's an in-ear design, so it blocks your ear canal and relies on ear tips (six sizes included) rather than resting on your head; the ANC figures also drop hard once ANC is on (40H total instead of 60H).
• ROEL-PLAY Over Ear — biggest strength: 40mm dynamic drivers in an over-ear shell, Bluetooth 5.4, a foldable frame, and a 3.5mm jack for wired listening when Bluetooth isn't an option.
• ROEL-PLAY Over Ear — biggest trade-off: Its noise control is sound isolation, not active noise cancellation, and the Bluetooth range is listed at 10m versus 20m on the TOZO.
• Who each is for: TOZO NC9 for commuters, gym-goers, call-heavy workdays and anyone who wants ANC plus a waterproof rating; ROEL-PLAY Over Ear for people who prefer over-ear comfort, retro styling and a wired fallback.
The NC9 is built around two jobs: quiet and calls. Hybrid active noise cancellation with a maximum reduction depth of 45dB is the headline, and there's a Transparent Mode when you'd rather hear traffic, announcements or a barista than your playlist. That combination is exactly what you want for a commute, an open-plan office or a flight.
The call side is where the "ENC" part of this comparison really lives. Six microphones work with ENC ambient noise reduction to filter background sound, which is the setup you want if you spend your day on meetings rather than just listening. Sound comes from 10mm dynamic drivers with OrigX Acoustic 2.0 tuning, and the TOZO app gives you 32 EQ options plus the option to share a custom EQ in the app's sharing zone. Touch controls handle playback and noise modes, and the app covers both.
Battery is the other reason to pick these. The case is rated for up to 60 hours total with ANC off and 40 hours with ANC on, with single-use playback of 14 hours (ANC off) and 10 hours (ANC on) after a full charge in about 1.5 hours. The case also displays remaining battery so you're not guessing. Add Bluetooth 5.3, a 20m range, 60ms audio latency for video and gaming, an IPX8 waterproof rating, six sizes of replaceable ear caps and a 32-ohm impedance, and this is a do-everything pair of earbuds.
Who should skip it? If you dislike things sitting inside your ears, if you want a headband-style set you can slide on and off, or if you want a wired option as a backup, the NC9 isn't that product. It's earbuds, full stop.
The ROEL-PLAY Over Ear goes the other direction: it's a retro-styled over-ear headset with leather-grain texture, matte metal accents and a brown finish, plus a metal telescopic arm you can adjust to fit. If you've ever wanted headphones that look like something from a few decades ago instead of another slab of black plastic, that's the whole pitch here, and the foldable design means it packs down instead of taking over your bag.
Sound comes from a professionally tuned 40mm dynamic driver with balanced three-frequency output and a spatial stereo effect that's aimed at music, video and games. Bluetooth 5.4 handles the wireless side with quick pairing and a stable 10m connection, and low latency keeps audio from lagging behind the picture during gaming or streaming. The controls are push-button rather than touch, which some people genuinely prefer because you can feel what you're pressing.
That 3.5mm jack matters more than it looks. It means the ROEL-PLAY works as a wired headset too, so you're not stuck if you want to plug into a laptop, an in-flight system or anything without Bluetooth. Battery is stated as up to 200 hours of standby with a 2-hour full charge, and the ergonomic over-ear shape is made for long wear sessions. Noise control is sound isolation — the passive kind you get from the ear cups pressing around your ears, not active cancellation.
So who should skip it? Anyone who needs real ANC, anyone who wants earbuds for the gym or rain, and anyone who wants app-based EQ tuning. There's no app control listed here and no IP rating, so treat it as an indoor, casual, desk-and-travel headset rather than a workout companion.
Side-by-Side: Which Should You Choose?
• Best for calls and online meetings → TOZO NC9. Six microphones with ENC ambient noise reduction is the more call-focused setup of the two.
• Best for over-ear comfort and retro style → ROEL-PLAY Over Ear. 40mm drivers, adjustable metal telescopic arm, foldable frame and leather-grain brown finish.
• Best for long sessions away from a charger → ROEL-PLAY Over Ear. Up to 200 hours standby on a 2-hour charge, versus 60 hours total playback for the TOZO case.
• Best for the gym, rain and sweat → TOZO NC9. IPX8 waterproofing and six ear tip sizes; the ROEL-PLAY has no water-resistance rating listed.
• Best for gaming and video sync → a split decision. TOZO quotes 60ms latency with Bluetooth 5.3; ROEL-PLAY claims low latency on Bluetooth 5.4 with a 10m range versus the TOZO's 20m.
• Best for wired fallback → ROEL-PLAY Over Ear. Its 3.5mm jack is the only wired option between the two.
• Best for sound customization → TOZO NC9. 32 EQ options and an EQ sharing zone through the TOZO app, plus app-based noise control.
In my opinion, the TOZO NC9 is the stronger buy for most people, because it covers the widest range of real situations: ANC for commuting, six-mic ENC for calls, IPX8 for weather and workouts, app EQ for tuning, and a case that tells you how much battery is left. I'd pick the ROEL-PLAY Over Ear instead if over-ear comfort, retro styling and a wired 3.5mm option matter more to you than noise cancellation — it's a genuinely appealing desk-and-travel headset, just a more specialized one. Check the current price on Amazon for both before you commit, since value swings with whatever each is going for that day.
FAQ
how to use wireless headphones mic on pc
how to use mic on wireless headphones
Just wear them and talk — the microphones are built into the headset, so there's nothing to plug in. On the TOZO NC9 the six mics work with ENC to reduce surrounding noise; on the ROEL-PLAY the ENC mic does the same job with sound isolation around your ears. Keep the mic reasonably close and avoid covering it with a hand or scarf.
can you use bluetooth headphones as a mic
Yes. Any Bluetooth headset with a built-in microphone — which both of these are — can act as a microphone as well as a speaker. Your device simply needs to treat it as a headset rather than headphones only, which is a setting in most operating systems. Both models list Bluetooth as their wireless technology, so voice input works over that connection.
do all bluetooth headphones have a microphone
No. Bluetooth is a wireless audio standard, not a promise of a microphone; plenty of Bluetooth headphones are listen-only. What matters is whether the maker specifies mic technology, and here both do: the TOZO NC9 lists six microphones with ENC, and the ROEL-PLAY Over Ear lists an ENC mic. If calls are your priority, look for that wording rather than assuming.
