If you want a lightweight neckband pair built for long calls and TV audio with almost no delay, choose Avantree Neckband Headphones Earbuds; if you need a dual-mode over-ear headset that jumps between 2.4GHz gaming and Bluetooth for your phone, choose Ozeino 2.4GHz.
• Avantree's biggest strength: A 24–28g neckband design with magnets that hold the earbuds together, plus up to 20 hours of playtime — built for all-day wear.
• Avantree's biggest trade-off: Bluetooth 4.1 only. For low-latency TV audio with traditional TVs you need a compatible Avantree transmitter, and the NB16 pairs only with specific transmitter models.
• Ozeino's biggest strength: Dual 2.4GHz and Bluetooth 5.3 connectivity with a 50mm driver and up to 40 hours of battery — one headset that covers console, PC, and phone.
• Ozeino's biggest trade-off: It's an over-ear gaming headset with RGB lighting and a flip mic. That's a lot of headset if you just want something discreet for phone calls.
• Pick Avantree if you want a light, tangle-free neckband for phone calls, workouts, and TV with minimal audio delay.
• Pick Ozeino if you want one wireless headset that handles PS5, PC, laptop, Mac, and mobile — with gaming-grade low latency thrown in.
The Avantree NB16 is a neckband-style in-ear headphone. The earbuds are magnetic, so they snap together and hang around your neck when you're not listening — no loose wires swinging around, no digging in a pocket. There's an inline remote for calls and music, which keeps the controls in a place you can find by touch. At roughly 24–28g, this is about as light as a wireless headphone gets, and the flex-form neckband plus the included ear tips and wingtips are aimed squarely at a secure, forget-you're-wearing-it fit.
The headline number is battery: up to 20 hours of continuous talk or music, with a 2-hour charge time. That's a full workday of calls with room to spare, and it's why I'd point commuters, remote workers, and gym-goers here first. Bluetooth range is a standard 10 meters, impedance is 32 ohm, and the frequency response spans 20Hz–20,000Hz — a normal, full-range profile for music and voice. The chipset is Bluetooth 4.1, which is older, and it's worth being honest about that.
The real catch is TV audio. The NB16 connects directly to Bluetooth-enabled smart TVs, but for traditional TVs with optical or AUX ports you'll need a compatible Avantree transmitter — and only specific ones. Per the spec sheet, the NB16 pairs with the older HT4186/HT41866, the Audikast series (excluding Audikast 3), and Oasis/Oasis Plus. If you have the newer 418P-3, HT4186-Q, or HT41866-Q transmitters, you'd need the NB16-Q model instead. So if your plan is "plug into any old TV and go," check your transmitter first. If you want a light neckband that just works with your phone, this is a clean pick. It ships with a carrying case and a 2-year warranty.
The Ozeino OW810 is a different animal entirely. It's an over-ear wireless headset with a flip microphone, RGB gradient lighting, and dual connectivity: a 2.4GHz USB dongle (with both USB-A and USB-C ports) and Bluetooth 5.3. That dual-input design is the whole point — you can run 2.4GHz for your PS5, PS4, or PC to get under 30ms latency, then switch to Bluetooth for your laptop, Mac, or phone without swapping headsets. The spec sheet frames the 2.4GHz link as lossless with less than 30ms delay, which is the number that matters in competitive games.
The audio side leans gaming. A 50mm dynamic driver, 36 ohm impedance, and a 20Hz–20,000Hz range — the larger driver is aimed at bass and positional accuracy, so you can pick out footsteps, reloads, and dialogue. The mic is noise-cancelling and flexible, and the controls are laid out for quick volume, mute, and call answering. Battery is rated up to 40 hours, and it supports charging while playing, so a long session doesn't get cut short. There's also a 3.5mm jack, meaning you can go wired if you want.
Who should buy it? Anyone who wants one headset to cover console, PC, and mobile, and who values low-latency wireless for games. If you're a phone-first user who mostly makes calls and listens to music on the go, the Ozeino is heavier and more conspicuous than you need — it's over-ear with lighting and a boom mic. And note the Bluetooth version field reads "5" while the feature copy says 5.3; either way, it's a modern Bluetooth generation versus Avantree's 4.1.
• Best for phone calls and everyday Bluetooth → Avantree Neckband Headphones Earbuds. The inline remote, magnetic earbuds, and 24–28g weight make it the more natural phone companion.
• Best for battery life → Ozeino 2.4GHz. Up to 40 hours versus Avantree's 20, and it can charge while you play.
• Best for low-latency gaming → Ozeino 2.4GHz. The 2.4GHz dongle with under 30ms delay is built for PS5, PS4, and PC.
• Best for TV with minimal audio delay → Avantree Neckband Headphones Earbuds, but only with a compatible Avantree transmitter. Check the model list before you commit.
• Best for discreet, lightweight wear → Avantree Neckband Headphones Earbuds. No boom mic, no RGB, just a neckband you can forget about.
• Best for one-headset-everywhere flexibility → Ozeino 2.4GHz. Dual 2.4GHz and Bluetooth 5.3 covers console, PC, laptop, Mac, and mobile.
• Best for wired fallback → Ozeino 2.4GHz, thanks to the 3.5mm jack.
• Check the current price on Amazon for both before deciding — the design differences matter more than the sticker, but your budget still decides.
If your priority is Bluetooth headphones for your phone — calls, music, workouts, and light TV use — I'd buy the Avantree Neckband Headphones Earbuds. In my opinion, the 20-hour battery, magnetic earbuds, and 24–28g neckband make it the easier everyday companion, as long as you're fine with Bluetooth 4.1 and you confirm your transmitter model if TV audio is the goal. I'd only steer you to the Ozeino 2.4GHz if gaming and multi-device switching are the point — that's where its 2.4GHz mode, 50mm driver, and 40-hour battery earn their keep. Two good headsets, two different jobs.

Turn the headphones on and put them in pairing mode. On your phone, open Settings, go to Bluetooth, and select the headphone's name from the list. The Avantree NB16, for example, pairs as "Avantree NB16" and enters pairing mode automatically on first use, with the LED flashing red and blue.

You don't need the phone to disconnect. Power the headphones off, or move out of Bluetooth range (about 10 meters on the Avantree NB16). You can also toggle Bluetooth off on the phone itself — no app is required for either headset.

Power the headset on and hold it in pairing mode until the indicator flashes. Then open your phone's Bluetooth menu and select the device. The Ozeino OW810 also supports a 2.4GHz dongle mode for PC and console, but for phone use you'll want its Bluetooth mode.
